  • Non HTML coverage report generation using E-manager

    Hi, After my specman regression is complete, I am trying to generate a non-html coverage report using E-manager. When i explored the E-manager tool, I could only see HTML report generation options. Is it not possible to generate non-html reports? or atleast any work around to generate one from html?...

  • Re: assertion in e

    Another thing I forgot to mention. The event a_ev is a different thing from the expect a_ev. You've used a named expect (expect a_ev is ....). You're allowed to do that in e, since the event and the expect are 2 syntatically different things. Again, fo an on block on the expect, just use the...

  • Re: assertion in e

    Hello redrabbit, I think a basic spmn training class would be really helpful. Questions like this one and others you've submitted recently would be answered there... Specifically to the above, a_ev doesn't seem to be emitted anywhere, so as you rightly notice it doesn't ever happen. Looking...

  • Exclude functional coverage for particular test

    Hi All, I am running regression for my SOC and that list contains the register write-read test also, and because of that my vr_ad functional coverage is 100%. Is that any way/switch by which for register write-read testcase i can disable collecting the functional coverage in SPECMAN. Thanks...

  • Re: using an event inside a TCM

    Yes, events are definitely used in TCMs. However it's considered very bad practice to make hierarchical references like your sys.top.phase_monitor.data_valid.This is because you break all the re-use rules, assuming that the phase_monitor will always be located under sys.top an so on. This means your...

  • vr_ad reset check

    Hi all, When we define as vr_ad reg_fld for each reg_file we used to provide the reset value of each field. As i know the application for this is when we call reset() function for that reg_file it will overwritten with a reset value whatever we have assigned. My doubt here is can it be use for...

  • Re: "list of uint(bits:8)" versus "list of byte"

    So far as I recall, it doesn't matter. The only performance problem comes if you make the uint bigger than the number of bits in the CPU architecture, as that impacts the way the data gets stored.
