[SOLVED] Questasim error - (vish-4014) No objects found matching 'sim:/......'

[satishsa]

I am migrating to questasim 10.3c from an older version of the tool. I use a 3-step compilation process.

vlog
vopt
vsim

I noticed after the migration that I am unable to view any of my assertions in the wavefoem and am greeted with the message:

# (vish-4014) No objects found matching 'sim:/.................'

I did some investigation and saw that during my vopt compilation, I had the flag +acc=a set. Although this should work for PSL and SystemVerilog assertions (according to the manual), It wasn't.

I decided to just enable "+acc" which allows all flags. Less optimal, but should solve my problem. Nope, it did not.

At this point the only other choice I have is to not optimize using +novopt but I do not want to do this. Any idea why this isn't working as expected?

Thanks

Did you try vsim -assertdebug

Did you try any of the examples in the examples/systemverilog/assertions directory?

Thanks Dave for your reply

I do have -assertdebug in my vsim arguments.

I haven't tried the examples in the directory you mentioned. These assertions were viewable in Questasim 10.1 so I would assume Mentor would try and maintain the same functionality.

I found that rather than dragging the assertion from the objects window into the wave window, by going to View->Coverage->Assertions, I can easily view all assertions.

I guess this is the right way to do it anyway.

Hello Dave/Satishsa,

I am also facing the same issue.

I have migrated VE from 10.1 to 10.3e.
During this migration, I am seeing assertion loading issue.

I am using "+acc" argument in vlog command and -assertdebug argument in vsim command of Makefile.

Using this Makefile, I am able to see the assertion in waveform with 10.1 without any error whereas getting "vish-4014 No objects found matching" error with 10.3e.

I have gone through User reference Manual and found that if we use wildcard to load object, It will exclude assertions, variable etc object type.

After this I have removed "Assertion" from WildcardFilter setting of modesim.ini and run simulation. Now assertion is loaded into instance window.
But If I try to load assertion into waveform window then showing same (vish-4014) error.
Then I have removed * from add wave command in transcript window and tried to check. That time I am able to see the assertion in waveform window.

Please suggest if there is any generic way to overcome this manual process.

Also I have noticed that in 10.2C version with same Makefile and updated 10.2C modelsim.ini file (for WildacardFilter) ,
If I run simulation and add assertion into waveform window then without removing * from add wave command, I am able to see the assertion in waveform window.

Please suggest for this discrepancy.
