I am generating code coverage results for a design, but for some reason there are a couple of modules that are missing in the coverage report. I am using the imc tool to generate coverage, and have "-coverage all" specified when simulations run. I am not using the deselect_coverage, and there are no pragmas in the rtl to turn coverage off.
Has anyone else seen cases where certain modules for some reason do not get coverage results? Or what can cause this.
