How do I read cover-user information #1362
Comments
Original Redmine Comment Perhaps you are missing the save of the coverage data? See the examples/tracing_c files it does coverage. |
Original Redmine Comment Thank you so much for pointing me to this example - that solved the generation issue! Running verilator_coverage I can also get the total statistic number, but no details. Is there also a method/tool to create graphical visualization of the coverage points in the coverage.dat file? |
Original Redmine Comment Perhaps you forgot to give the --annotate option? At present output is always ASCII. Patches for improving to add e.g. HTML output would be welcome. Closing as think no problem here, but ask more if needed. |

As part of measuring coverage and validation quality, I have now successfully added SVA cover points and an SVA bind file to the compilation of the Verilog design that I am currently working with.
I believe that I have also enabled the coverage by adding --assert and --coverage-user to the flags when I call verilator.
However, when I run the coverage enhanced design with test cases that should activate the cover points, I still do not see any generated coverage output.
Can somebody please tell me what I am missing:
Thanks,
Flemming
