Hi, Thanks in advance for your insights and recommendations.
Overview:
I have several tests that I’d like to use to collect coverage on. E.g., let’s say I wanted to collect address coverage to a memory that I randomize in the test.
I intended on creating an address_coverage class. However, the ‘address’ attribute is set in my test, not in that class.
Question:
If using a coverage class, is there a preferred way to pass it the attribute that is to be covered? Some thoughts:
- I could copy the value to the class attribute before calling .sample(); this works but…
- I was hoping I could pass the attribute in my sample command, like …sample(memory_address) but I don’t see anything suggesting it can be done.
- Is there a clever way of using a reference link to assign the class’s attribute to my test attribute so I don’t have to manually every time I sample? E.g., in ‘C’ I could change the address of a variable.
Thanks for your suggestions,
Brian
p.s., I’m familiar with using subscribers to do this with TLM style transactions, but not using them here.
