fpga device utilization file

[Keith GD-AIS]

When sbRIO complier is finished compling the FPGA code where does it put the FPGA device utilization file? And any other build files for that matter. I want to know how much of the FPGA I have used and how much I/O I have availible once the current code is done compiling. Thanks, Keith

When you compile your FPGA code, all of the information is in the compilation status window.  If you want to see it after the fact, then you will have to look at the logs.  While the FPGA code is compiling, you will notice in the summary at the bottom a directory.  That directory (on Windows 7 at least) is c:\NIFPGA\compilation\.  Here you can look at the code generation report, and the build results.  They aren't the prettiest reports to look at, but the information is there.

Post compile you can also view compilation results (in LabVIEW FPGA 2010) by right-clicking on the FPGA Build Specification and selecting Display Compilation Results.  Within the compilation status window that appears, you can then select the Final Device Utilization (map) report for a summary or the Xilinx Log for a more detailed utilization breakdown (including RAM, Mults, etc.) which needs to be manually parsed.  This method keeps you from digging in the FPGA compiler folders.

Prior to LabVIEW 2010 and the build specification for LabVIEW FPGA, these logs could be viewed by right-clicking on the FPGA VI in the LabVIEW project and selecting Target-Specific Properties... (obscure, I know) 🙂
