How do you read the FPGA bitfile version?

[D*]

I notice that there is a "Version Number" in the FPGA build dialog on the "Information" page.  So, the Version Number should be getting written to the .lvbitx file.  How does one read this version number back out from a .lvbitx later?

Unfortunately you cannot. If you open up the .lvbitx file in a text editor you will see an xml tag for the build version but it's never populated. Bug 811948 (CAR 494874) describes this incorrect behavior.

OOf. That CAR is older than my kids!

Hi,

I faced the same issue when trying to use the BuildSpecDescription to keep track and version our bitfiles for our CI system.

There is a workaround just found in the discussion here, if it helps.

Thanks,

Cris
