    Coverage results over the time (RTL) Reply

    Is it possible to track the coverage results over the time? For bug detection, it is well accepted that the rate at which bug are detected approximates an exponential decay. That is at beggining is should be easier to detect bug, then it becomes more an more complicate. We can distinguish between easy and hard-to-detect bugs. The trends can be depicted in this chart:

     Can I register toggle or block coverage at RTL with timing information for printing a similar chart?

    Yes you can with Enterprise Manager.

    Do you know if it is just a matter of flags to be passed to ncsc_run and then I have to open the coverage-result file in Enterprise Manager? Or do I have to create a specific testbench (e.g., UVM, e, ...)?

     Thank you.

    You won't have to modify your testbench but you will need to collect your runs into the groupings to reflect the simulations over time.

    You'll want to work with your local Application Engineer to get some guidance on this.
