Hi Jim

Thanks for fixing this.

Hi Jon,
Thanks for sticking with this one. Knowing which version of Questa you had made told me I needed to search harder in VendorScripts_Questa.tcl. I found the issue. It is fixed on Dev.

If you do not want to update to the Dev branch, you can edit the line in VendorScripts_Questa.tcl that says:
set SimulateOptions [concat $::VsimArgs…[Read more]

I am not sure what I am doing wrong. I am using the latest Questa base so I am using the VSIM/VOPT flow.
I compiled GLBL into my common_tb library where are the other design files are located. It just seems the issue is with the vsim command. Having coomon_tb.glbl makes it fail with the error shown in the previous post.

vsim -c -t ps -lib…[Read more]

Which version of Questa are you using?

Historically Questa offered either a vsim or a vopt/vsim flow. Up until 2025, OSVVM only supported the vsim flow, but supports both vsim and vopt/vsim flow.

The startup VendorScripts_Siemens.tcl supports the vsim flow. VendorScripts_Questa.tcl supports the vopt/vsim flow.

To choose which one you…[Read more]

To summarize I dont think its necessary to have GLBL in a seperate library. It seems as though I need to have GLBL in the vopt step but not in the vsim step. The following works, the only difference is that GLBL isnt included for the vsim step. If I use the script then it is included and the simulation wont start because of the error below.

Hi Jim

I compliled GLBL into its own librrary but that didnt help. It seems that I need GLBL included for the vopt step but not in the simulate step. I manually added -L xilinx_glbl to the vopt command and that seemed to work. But I am not sure how I make the script add the library to vopt.

Thanks

Jon

If you make this call:
SetSecondSimulationTopLevel glbl

Then OSVVM would do:
vsim -c -t ps -lib common_tb TbStream_SendGetBurst1_opt glbl -suppress 8683 -suppress 8684

That said, since a library is not specified for glbl, Questa will assume it to be in common_tb. So as a result, Questa may add the common_tb.glbl in their interpretation of…[Read more]

It seems that the issue is to do with the Questasim vsim command. The script is doing the following

vsim -c -t ps -lib common_tb TbStream_SendGetBurst1_opt common_tb.glbl -suppress 8683 -suppress 8684

If I remove the common_tb.glbl in the above the it runs.

Hi Senthil,
This is now fixed on the dev branch of OsvvmLibraries on GitHub. You can get the dev branch by doing:

git clone --recursive --branch dev https://github.com/osvvm/OsvvmLibraries
