modelsim coverage

hi,

Firstly, u need to compile ur design file with ur selected coverage. For example,

ModelSim > vlog -cover bcst file_name.v

Here, ur coverage are b=branch, c=condition, s=statement and t=toggle.

then,

ModelSim > vsim -coverage file_testbench.v

next, run -all.

OR, u can enable it using GUI. U go to Compile > Compile Options and select the Coverage tab.
Another option, u just right-click on ur design file at "Project" and choose "Properties". Now, u can see coverage tab.

Hope it helps.

vsim coverage

Hi,

ModelSim Altera is not the same as ModelSim PE or SE version. I did check on Altera website.

The ModelSim Altera edition software is licensed as a single language—either VHDL or Verilog HDL for each active subscription—and only supports Altera gate-level libraries.

It can do behavioral simulation, HDL testbench and TCL scripting.

U can check on Altera website:
https://www.altera.com/products/software/products/model/eda-ms.html#question_1

Now, back to ur next Q. What should I do for coverage?
Dude, u can request for software upgrade ...buy ModelSim PE or SE version.

failure to license for coverage

Thanks buddy for ur interest....

I have modelsim PE version as well (node lock license), but it's code coverage is also disable.

Now questn is i have node lock license for PE version, still why that option is not present??
I think is there any option that i have to enable, which inturn enables code coverage??

And as far as evaluation version is concern, Is any modelsim's evaluation version allows to do code coverage??

regards..

modelsim toggle

Hi, thanks for the help point.

Anyway, in my office we use ModelSim SE Plus 6.1 working both OS Linux and Windows XP.
Did u try all the methods tht I gave u earlier to enable coverage option in PE? Was there any warning or error message?

Another thing, ModelSim PE with node lock license has a limitation. The limitation is it can only have one simulation invoked with a node lock license.

Thus, I assume tht someone already invoke the vsim and at the same time u r also trying to invoke. So, tht is why u can use the coverage option.

As for evaluation version, I not sure. It should allow all features unless u request for specific feature only. This is only my personal opinion.

coverage in modelsim

Hi no_mad

I have tried enabling option in modelsimPE, but it shows license error. I think coverage license is not included in that..

any way now i think only option is evaluation license wit special request of code coverage. Lets c if possible or not.....

Thanks!!!!!!!

u can try out some gnu tools like "covered" for code coverage.....other gnu tools are available for functional,toggle coverage as well...
