ERROR:HDLParsers:851

[穆易]

When I Compile my FPGA Program,I got a error below ERROR:HDLParsers:851 - "C:/NIFPGA85/srvrTmp/LOCALH~1/FPGASY~1/rvi_FPGAMINUSIgnitionControl_vi_FPGACompileCopy1.vhd" Line 881. Formal Clk of SubVICtlOrInd with no default value must be associated with an actual value. xflow-Program Xst returned error code 6 Aborting flow execution

Hello,

Please look inside the VI called 'FPGA-IgnitionControl.VI' that contains a indicator named 'resetFire' that is not wired to anything. I believe that one is causing the issues you are experiencing. Please wire something to it and then recompile your application. Hope this helps!

thanks for your advice, jimmie. the problem is solved.

but at the end of compiling,I got another error:

Error:XFlow-bitgen:管道已结束

Error:XFlow:42-Aborting flow execution

Hello,

I am not sure what the non-English words refers to above I am afraid but I found some information about the XFlow:42 error. I would guess that is due to the fact that your FPGA is too big and cannot fit on your FPGA target and that you might need to optimize the code in respect of resource usage. We have some information on what to think about when it comes to minimize the resource usage.

If you open up your Compile Server (C:\Program Files\National Instruments\LabVIEW 8.5\rvi\compileServer.exe) and press on the button that says ‘Compile List’ you will find a history list of all your compilations. Find the latest one, the one that failed with the error above, and look at the resource usage (slices, multipliers and such).

Finally you can also get similar issues if you have no disk space left on your development machine. Delete the files in these folders:

X :\NIFPGA85\clntTmp and X :\NIFPGA85\srvrTmp, where X is the drive on which you installed LabVIEW and the FPGA Module, to save space on the hard drive.
