Cove coverage in Questasim while Cosimulating with Simulink

Hi All,

I'm trying to get code coverage analysis report while cosimulation of generated HDL code through Questasim in Simulink. I'm getting blank results in coverage analysis section of Questasim. Can you please help me to get code coverage details ? Thanks in Advance.

Matlab: 2022b

Questasim: 2020.1

Hey Prashant,

Please ensure that you have enabled proper flags for your QuestaSim simulation. For example you could use the option "+fcover" to enable function coverage during the simulation.

You can save your report in a UCDB file and then generate the result in a html file.

vcover report -details -html result.ucdb 

I would suggest to first try to get code coverage report by following the example for generating code coverage report using QuestaSim:

I hope this helps!

Thank you for your answer Shubham.

Meanwhile I find an another way to enable code coverage. You can make the changes mentioned below in Simulation options of CoSimulation Wizard tool.

-t 1ns -coverage -voptargs="+cover=sbceft"

You will get code coverage in Questasim tool During cosimulation using this command.

Thank you again.
