ERROR: [XSIM 43-3225] Cannot find design unit RTP_UL.RTP_UpLink_TM3 in library work located at xsim.dir/work

Jump to solution

Hi,

I am trying to simulate a large design, and one of my sources under the top module is mysteriously not present in the heirarchy of the scope window once simulation opens (It is the instance of RTP_UpLink_TM3), even though it is present in the sources heirarchy.

So, in order to try to investigate the problem further, I set the missing file (RTP_UpLink_TM3) as the top simulation module and ran simulation. Then I got this message:

ERROR: [XSIM 43-3225] Cannot find design unit RTP_UL.RTP_UpLink_TM3 in library work located at xsim.dir/work

RTP_UpLink_TM3 is part of a VHDL library in my design named RTP_UL. I verified several times that it is indeed set to that library. All of the sources are VHDL (not 2008). I tried resetting the simulation, deleting the entire simulation folder and restarting. I tried restarting Vivado several times. I tried reading all the other threads that looked similar to my problem.

If compilation failed, the design unit was not compiled to the desired library and probably the error.

Hi Raj,

Thank you for the help. I tried running this command on the RTP_UpLink_TM3 file, but the error did not go away.

Any other suggestions?

I was able to solve the problem. The problem was that some of my code (lower down in the hierarchy chain) was trying to open a memory init file that was not present.

Would anyone be able to provide an explanation of what xsim.dir/work is, and why that particular error might have been flagged?
