Every now and then, a colleague asks me, ‘How do I get Toggle coverage for a 32-bit timer counter?’.
It’s hard to get into the internal code when 3rd party IPs are encrypted, and even if I can, I don’t have any ideas off the top of my head.
Please help. How do I get toggle coverage for a 32bit timer counter? Do I simply check toggle coverage for a certain range and exclude or waive the rest?
First of all, you should never have to do code/toggle coverage on encrypted IP–that’s the job of the IP provider. You can check on the connections to it. It’s also wasteful to build a 32 bit counter if you only need 10 bits of it. Tools can give you toggle coverage quite easily. Check your user manual.
