29.1.1 SystemVerilog API
The following criteria are used within this API.
1) This API shall be similar for all coverages
There are a wide number of coverage types available, with possibly different sets offered by different vendors. Maintaining a common interface across all the different types enhances portability and ease of use.
2) At a minimum, the following types of coverage shall be supported:
a) statement coverage
b) toggle coverage
c) fsm coverage
i) fsm states
ii) fsm transitions
c) assertion coverage
3) Coverage APIs shall be extensible in a transparent manner, i.e., adding a new coverage type shall not break any existing coverage usage.
4) This API shall provide means to obtain coverage information from specific sub-hierarchies of the design without requiring the user to enumerate all instances in those hierarchies.
