Open source EDA / electronics CAD software for Windows, macOS and Linux. Use schematic capture, design PCB layouts and view them in 3D, all forever free. If you do not need dark current compensation you can remove the second photodiode and leave the pads open. The software reads the data using a clock which is driven by the ADC. The clock frequency is the same as the sampling rate (20MSPS). PCB is a free, open source and interactive PCB editor available for Windows, Linux, Mac and UNIX systems. PCB includes many professional features like 16 copper layers, auto-router, trace optimizer, DRC etc. While PCB is the printed circuit board layout tool, gEDA is the free schematic capture software.
ProntoCAD-CONNECT is the importer engine featured in all Unisoft software modules and allows the importing of virtually any CAD, Gerber, Bill of Materials (BOM), CNC and mechanical drawing formats.

Importing Your CAD Files
Importing your CAD files is easy with the Unisoft software! The 'SMART OPEN' feature is your CAD EXPERT that does all the work for you finding and sorting out all the proper files in your project folder!
TO USE 'SMART OPEN': From the Unisoft software click FILE from the main menu, click SMART OPEN and a new window opens. In the new window browse to and select the directory that your project CAD or Gerber files are located in. A new window opens and select one of the files presented and your PC Board will be displayed.
The SMART OPEN feature looks at all the files for your project in the folder you select and then presents you with only the correct PC Board, CAD and Gerber files that can be imported into the Unisoft software with the most desirable CAD files at the top of the list.
MORE ABOUT CAD FILE IMPORTING:
The Unisoft software can import the wide assortment of CAD, Gerber, BOM and XY rotation files that EMS/CEM and OEM electronic manufactures encounter. Unisoft has a set of the best ECAD, Gerber and BOM importers in the world today. This software developed over the last 30 years imports all types of ECAD, MCAD and BOM formats.
Unisoft imports the ASCII text files created by CAD systems and supports revision levels dating back to the 1980's and this can be important because older versions of CAD systems are still in use and need to be supported. For example the PADS ASCII output .ASC file format dates back to the 1980's and Unisoft supports virtually all the variations PADS created through the years within that format.
Unisoft SMART OPEN feature outlined previously above, will scan all files in a folder and will automatically detect the CAD files which have correct content for importing into the Unisoft software. So for example if you have a folder containing 40 assorted CAD, Gerber, BOM and Drawing files for a PC Board project use the Unisoft SMART OPEN feature by clicking FILE from the main menu then click SMART OPEN and point to the directory folder with the files and click OK and you will be presented with a list of the CAD files you can import. In general look for at a minimum 'PCB pin x-y' in the field 'Contains this type of data'. If the file contains 'PCB pin x-y' data then usually with the Unisoft software this will be sufficient data to program your Assembly, AOI inspection and selective Soldering equipment; and also create process assembly sheets, kitting labels, costing reports, do first article and general inspection.
If you are having trouble finding the right type of CAD file to import into the Unisoft software then the table below lists PC Board CAD, Gerber and mechanical CAD file formats that maybe imported into the Unisoft software. You can use this table to match up the correct CAD file required to be imported. After you have installed the Unisoft software full samples of most of the CAD formats listed in the table below can be found by default in the directory c:program filesunisoftcad-import-file-samples-etc or c:program files(x86)unisoftcad-import-file-samples-etc . In that directory the sample files start with SAMPLE_ and the CAD System is in the name of the file, for example the file SAMPLE_PADS.ASC is a full sample of the PADS CAD system ASCII file. If you are having trouble finding the right type of CAD file then use these samples to match them to the CAD files your CAD department or your clients may have available for processing with the Unisoft software. For example if your company or client uses the OrCAD CAD system to design their PC Boards and they have not sent you the correct files then use the table below to have them send you the desired files. From the table below under the field 'CAD system' look for OrCAD and you will find two listings. Next under the field 'File label or type' you will find 'Min File' and 'GENCAD'. Under the field 'Contains this type of data' you will find that both have the same listing of 'PCB pin x-y,netlist,trace data'. The field 'Contains this type of data' indicates the PC Board data types contained in the file and usually the more types listed the better. In the case of OrCAD both the 'Min File' and 'GENCAD' files have full 'Contains this type of data' listings of 'PCB pin x-y,netlist,trace data' and either one will work fine for importing into the Unisoft software. Next look at the field 'Standard extension' and in the case of OrCAD they are .MIN and .CAD and if you have either of these files available you are ready to go; if not then request them from your client or your CAD department and do this by forwarding them the samples of the file formats you need and these samples are available by default in the directory c:program filesunisoftcad-import-file-samples-etc or c:program files(x86)unisoftcad-import-file-samples-etc . In the case of OrCAD the two files you would send them would be sample_orcad.min and sample_GENCAD.cad and these files should aid them in matching the correct file type you need.
STANDARD CAD FILES: Note that many CAD systems in addition to exporting their native format may export industry standard CAD formats such as GENCAD, GENCAM, FABMASTER, IPC-D-356, IPC-2581, etc. In most cases these files can be used in place of the native CAD files and are importable into the Unisoft software.
GERBER FILES: When CAD files are not available then Gerber files are often the only files available to Contract Manufacturers and OEM's. The Unisoft software can quickly translate these files into your required manufacturing files (see note 2 below).
X/Y CENTER & ROTATION FILES: When CAD files are not available then X/Y center & rotation files are often the only files available to Contract Manufacturers and OEM's. The Unisoft software can quickly translate these files into your required manufacturing files (see note 7 below).

BINARY FILES: The Unisoft software imports the ASCII files the ECAD systems export but it does not import their binary files. Binary PCB database files are the ECAD companies own proprietary binary format. These binary file formats are normally not public or documented and my violate copyrights. Also as an ECAD company releases new versions of it's software their binary format may change and it would be virtually impossible to modify the Unisoft software to accommodate these changes in a timely manner. For these reasons the Unisoft software does not import the binary files directly and only imports the standard ASCII files these ECAD systems export. TIP: If you try to open your CAD file with a TEXT editor and the characters are not standard ASCII text characters then it is most likely a binary file and not the ASCII CAD file and the Unisoft software will not be able to import it!
Note 1a:CAD files without explicitly defined component rotations: This CAD file does not have explicitly defined component rotations.
This CAD file has component pin information but no usable data about component rotations and in these cases Unisoft automatically calculates component rotations using standard zero degree package orientations.
Note 1b:CAD files with explicitly defined component rotations: This CAD file has explicitly defined component rotations.
This CAD file contains rotation information. When a CAD file is imported into the Unisoft software were the component rotations are explicitly defined in the CAD file then Unisoft assigns these explicitly defined rotations to the components.
In some cases it may be desirable to modify these explicilty defined component rotations. If this is the case then the RESET ROTATION feature can be used to change the rotation of the component package shapes in CAD files that have explicitly defined rotations. When the RESET ROTATION feature is used then the Unisoft software automatically calculates component rotations using standard zero degree package orientations.
Note 2:Gerber: Gerber data is basically a drawing file of the PC Boards pad information. Most of the systems listed above gerber data files. Gerber does not contain component, pin or netlist information. Wherever possible, from the table above, try to obtain CAD files with pin x-y,netlist,trace data. However as is the case with virtually all Contract Electronics Manufacturers [EMS/CEM] often the only data their clients provide are the gerber files. In this case the Unisoft GERBER-CONNECTION menu is used to quickly turn these raw Gerber files into intelligent data to program your Assembly, AOI inspection, ATE Test and selective Soldering equipment; and also create process assembly sheets, kitting labels, costing reports, do first article and general inspection.
Gerber files are exported by hundreds of different CAD and software systems. The first few lines of the GERBER file will look something like the sample below.
There is also a full sample of a GERBER file on your installation directory of the Unisoft software and by default it would be c:program filesunisoftcad-import-file-samples-etcsample-gerber.ger or c:program files(x86)unisoftcad-import-file-samples-etcsample-gerber.ger.
Note 3:Importing Cadence Allegro CAD files into the Unisoft software: Cadence Allegro is usually less straight forward then the other CAD systems in generating the necessary ASCII file that is then imported into the Unisoft software. The Allegro CAD system requires an extraction program in order to get the data out of the system. The extraction script exports ASCII files and therefore anyone needing PCB data from the Allegro database needs to use the Cadence Extraction program. Outlined below are two options to create the ASCII file.
Please note that the main Allegro binary database has a .BRD extension. The .BRD is in Allegro's own proprietary binary format that is not public or documented and Unisoft does not import this file directly. The Unisoft software imports the standard ASCII files this database can export.
Option #1 - Some Allegro systems (NT version for example) will allow you to export out an IPC-D356 ASCII file. IPC-D356 is created directly from the export menu on the Allegro CAD system and the Unisoft software can then import the IPC-D356 file.
To export IPC-D356 from the Allegro software click the EXPORT MENU then click IPC-D356 and the resultant .IPC file created can be imported into the Unisoft software. To import the .IPC file into the Unisoft software first start the Unisoft software and click the main FILE menu then select SMART OPEN and select the directory where the .IPC file is located, then select the .IPC file and click OK. A window will open, click OK and the PCB will be displayed.
Option #2 - Some customers that use ALLEGRO have been able to export the standard file format from ALLEGRO known as the Fabmaster 'extraction script'. We recommend this file format because it contains a large amount of the PC Board detail (pins, netlist, traces, etc.).
To export Fabmaster 'extraction script' from the Allegro software you need to download and run the skill file script to extract the Fabmaster 'extraction script' CAD data. The licensed Cadence Allegro user can go to 'Sourcelink' on the Cadence website and download the Fabmaster skill file to extract Fabmaster 'extraction script' CAD data. The skill file should contain information on how it should be run. The resultant Fabmaster 'extraction script' CAD file created can be imported into the Unisoft software. To import the file you can use the SMART OPEN feature in the Unisoft software and the PCB will be displayed. The other option to import the file is to make sure the file name is .FAB then start the Unisoft software and click the main FILE menu then select OPEN and select the directory where the .FAB file is located. Next click the pull down menu next to 'LIST FILE TYPES' and select 'FabMaster Files (*.FAB)' then select the .FAB file and click OPEN and the PCB will be displayed.
The first few lines of the file will look something like this:
Note if you are using an older version of Unisoft before year 2016 the following may apply. Newer versions will detect these differences automatically: If you have an ASCII file similar in format to the one above 'A!XXX!YYY!ZZZ!' but it does not import into the Unisoft software with the above mentioned methods then first change the file extension to .VAL and try to import it into the Unisoft software. If that does not work then change the file extension to .VA2 and try to import it into the Unisoft software. The format above 'A!XXX!YYY!ZZZ!' comes in many variations so if you still have issues then please contact Unisoft.
Note 4:Importing EAGLE PCB files into the Unisoft software:
Note that Eagle (CadSoft) was acquired by Autodesk in 2016 and so the export information below may change as the product is integrated into Autodesk..
----
EAGLE PCB system users can export GenCAD, IPCD356 and Fabmaster files that can then be imported into the Unisoft software. The Eagle PCB system uses 'User Language Programs' scripts to export data out. To download these user contributed scripts for GenCAD, IPCD356 and Fabmaster go to the Eagle website then click DOWNLOAD, then click ULP's — USER LANGUAGE PROGRAMS — and select the GenCAD, IPCD356 or Fabmaster download. Please follow any instructions provided on the Eagle website.
From either the schematic or board editor type the word 'run' (No quotation marks) and then press enter. A dialog will appear that will allow you to browse for the ULP you want to run, select the desired ULP and then click open. EAGLE will now execute the ULP.
Note 5:Altium Designer .PCBdoc / .PCB / .PRO: The .PCBdoc and the .PCB files from Altium Designer / Protel are normally file formats that the Unisoft software can import. Also other formats from Altium Designer that the Unisoft software can import is the Protel PCB 2.8 ASCII format.
PCBdoc/PCB: The .PCBdoc or .PRO file formats typically can be imported. To export these files from the CAD system click FILE then SAVE AS or FILE then SAVE COPY AS.
The .PCBdoc or .PRO top of the file header should look like the following:
Protel PCB 2.8: The Unisoft software can import from Altium Designer the Protel PCB 2.8 ASCII format. To export the Protel PCB 2.8 ASCII format from the SAVE AS menu on the Altium Designer CAD system choose the Protel PCB 2.8 ASCII format. This file will import correctly into the Unisoft software. The Protel file exported should have a .PRO extension but may have a .PCB file extension. If you use the preferred Unisoft SMART OPEN menu then it does not matter what the extension is. If you wish to open it with the Unisoft standard OPEN menu then the file should have a .PRO extension.
The Protel PCB 2.8 top of the file header will look something like the sample below.
There is also a full sample of this CAD file on your installation directory of the Unisoft software and by default it would be c:program filesunisoftcad-import-file-samples-etcsample_protel.pro or c:program files(x86)unisoftcad-import-file-samples-etcsample_protel.pro.
'PIN COORDINATE IS TOO LARGE' BOUNDARY LIMIT ERROR: If you are using Unisoft software version 5.11.11 or newer skip the following note because these newer versions of the software automatically adjust for the boundary limit error outlined here: If on importing the Protel PCB ASCII file into the Unisoft software you get the message 'Nothing to display!! Most likely a pin coordinate is too large. Failed.' then the PC board you are trying to import is usually outside the Unisoft software display size limits which is 65.536 inches by 65.536 inches (X=+32.767 to -32.767 and Y=+32.767 to -32.767). Usually the issue is that the PC Board when it was being designed on the CAD system was positioned towards the extreme corner of the CAD system display. So to fix this the CAD Designer simply needs to reposition the PC Board more towards the 0,0 origin of the CAD display and then regenerate the Protel PCB ASCII file. You should then be able to import this newly generated Protel PCB ASCII file into the Unisoft software. If you were to open the failing Protel PCB ASCII in a text editor you could actually see the coordinates that are too large. For example in the following file below on the fifth line we see the coordinate 36120000 and on rescaling this coordinate is 36.12 inches which is greater than our maximum limit of 32.767 inches.
Note 6:ODB++ (standard file format - Mentor Graphics/Valor ):
Importing into Unisoft: The Unisoft software can import the ODB++ format. ODB++ is not a single file format as most CAD type files but an array of files in multiple directories that usually have several levels of files. These files may or may not be in a single compressed file format such as .TGZ, .ZIP or .TAR . If compressed then to import the ODB++ file into the Unisoft software first make sure the single .TGZ, .ZIP or .TAR file that the ODB++ files are in is unzipped. Then when uncompressed you should see subdirectories with the names MATRIX, STEPS, FONTS, SYMBOLS, etc. Next from the Unisoft software click FILE from the main menu then click SMART OPEN and select the root directory where the ODB++ files are located then click OPEN and click OK. Click OK to close the Costing window and your PC Board is displayed.
About .TGZ and .TAR files: A file with the TGZ file extension is usually a GZIP Compressed Tar Archive file. TGZ files can be opened with most popular zip/unzip programs. Compressed archives are typically created by assembling collections of files into a single TAR archive, and then compressing that archive with gzip which then creates a .TGZ file. So basically most popular zip/unzip programs will work for opening .TGZ, .TAR and .ZIP files.
Note 7:X-Y Component center and rotation file: An X Y Center and rotation (XYR) file is any file containing component X Y center and rotation information. This type of file in most any format can be imported into the Unisoft software and is useful in creating Assembly and AOI machine programs. Our customers may find a file with similar data to that found in the XYR in their project CAD and BOM data folder. They can then use that file to import into the Unisoft software.
For example it may look like any variation of the following: Below are examples of files that contain reference designator, X/Y center and rotation formation in various formats. All of these files and more can be imported into the Unisoft software.
Please note that it is always preferable to use the other full CAD files listed above and not a XYR file as your first choice for importing into the Unisoft software.
For more details on XYR importing click here FEATURES and see 'Importing your X/Y Center, Rotation files'.
Note 8:OPTIONAL EXPORT OUTPUT: Generating this output may be an optional feature. Please check with the software provider for details.

There is also a full sample of this CAD file on your installation directory of the Unisoft software and by default it would be c:program filesunisoftcad-import-file-samples-etcsample_IPCD356.356 or c:program files(x86)unisoftcad-import-file-samples-etcsample_IPCD356.356.
Note 19: Unisoft is not aware of any full ASCII CAD file or any X,Y center rotation file export capabilities from this CAD system that can be used for import into the Unisoft software.
Since these data files are not available one other option is this CAD system can export Gerber's that the bareboard is made with. These Gerber files can then be imported into the Unisoft software and used to MAKE the component shapes on the PC board and at that point the files needed to program for your assembly, AOI and test equipment can be created. Also you can create assembly process documentation, kitting labels, do First Article Inspection, quoting, etc.
Refer to Note 2 above for additional information on Gerber files.
Note 20:AutoCAD DXF: AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs. AutoCAD .dxf files are a 'Design eXchange Format' files. This file type is only a drawing file. Unisoft can import and display these drawing files but they have little other value within the Unisoft software. For example you can not extract component, pin, x/y, netlist data, etc. from this type of file.
Note 21:ODB++ (Valor/Mentor Graphics software):
Exporting from the CAD System: From the Altium CAD system on the FILE menu select FABRICATION OUTPUT and select ODB++ FILE. You can now import this file into the Unisoft software. Note: Depending on the version of the Altium software, etc. this option may not be available.
Importing into Unisoft: The Unisoft software can import the ODB++ format. ODB++ is not a single file format as most CAD type files but an array of files in multiple directories that usually have several levels of files. These files may or may not be in a single compressed file format such as .TGZ, .ZIP or .TAR . If compressed then to import the ODB++ file into the Unisoft software first make sure the single .TGZ, .ZIP or .TAR file that the ODB++ files are in is unzipped. Then when uncompressed you should see subdirectories with the names MATRIX, STEPS, FONTS, SYMBOLS, etc. Next from the Unisoft software click FILE from the main menu then click SMART OPEN and select the root directory where the ODB++ files are located then click OPEN and click OK. Click OK to close the Costing window and your PC Board is displayed.
About .TGZ and .TAR files: A file with the TGZ file extension is usually a GZIP Compressed Tar Archive file. TGZ files can be opened with most popular zip/unzip programs. Compressed archives are typically created by assembling collections of files into a single TAR archive, and then compressing that archive with gzip which then creates a .TGZ file. So basically most popular zip/unzip programs will work for opening .TGZ, .TAR and .ZIP files.
When uncompressed you should see subdirectories looking something like those below.
Note 22: An export that maybe available from the Altium Designer CAD system is the IPC-2581 cvg file format. The first few lines of the IPC-2581 .cvg file will look something like the sample below. You can import this file into the Unisoft software.
