What are Munge files?

[Tnarg]

As far as I can tell a Munge file is a working copy of the fpga VI you are compiling.

Once the compile worker starts to compile the VI you can delete it.

As far as I can determine the compile process should delete the munge version of the file but it doesn't.

Where do you see "munge" files?

[Tnarg]

When I press run to compile an FPGA VI a window pops up "Generating Intermediate Files", the files that are used by the Xilinx Compiler.

The Munge File appears at this point. It's an exact copy of the FPGA VI I'm compiling except for the name which has "NI.Munge. prepended to the name.

The problem is this file overlays the original file so that if you don't notice the name change you can waste time editing the munge file instead of your file.

When you go to recompile your file you get a message stating that your file (the munge file) is not a project file.

See munge.rtf attachment.

Thanks for the information. The "munge" files are an intermediate copy of the source the LabVIEW FPGA compiler uses for processing. Normally users should NOT see these files. If there is some code you can share with NI and some steps to reproduce having the munge VI copy open that would be useful as it is certainly a bug.

I've tried compiling small programs and the munge file does not appear.

My project is fairly large (846 intermediate files, Xilinx 452 source files)

Total Slices: 43.8% (6281 out of 14336)
Slice Registers: 27.2% (7786 out of 28672)
Slice LUTs: 28.3% (8101 out of 28672)
Block RAMs: 50.0% (48 out of 96)

I work for the Canadian Department of Defence so I'm unable to share my project.

Hope this helps...

Hi Tnarg,

Can you create a program that does recreate the issue that can be shared?
