Hi Spartan,

Toggle Coverage is basically a check which tells the percentage of the I/Os of your module toggling with your test suite. If your test suite is exercising all the boundary signals of your module and none of the I/Os are tied or left dangling, then your toggle coverage will come up to be 100%.

Toggle coverage is generally needed in case of system level verification of your module. When your module is hooked up in the chip and you need to ensure that all the connections of the module within the chip are ok. This is basically to put focus on interface checking of your module in the chip.

Hope it makes sense.

what is toggle coverage

one cent:

toggle coverage is important for module internal verification.
the cases satified line coverage might not for toggle coverage, it implied the uncoverage is not triggered by pattern then you lost 50% coverage on the signal functionally.
ideally all the signals should be toggled by test-cases.

why toggle coverage is needed

yes, toggle coverage mostly checks all your subsystem connection!
