Coverage For SPI, I2C? Which Points to add?

OVM
1

Hi,

I am new-bee to OVM, but fine with SV. I have been assigned work with writing Coverage for I2C and SPI interface.

But when see the protocol I2C has just 3 output lines and so for SPI hardly 4. I am pretty confused on what to write as coverage and coverpoint.

Can anyone spark an idea or give a sample for these protocl on which point to cover for coverage. Its an urgent task, help me.

Well USB 2.0 is only 2 wires, but all respectable vendors have never ending list of coverage for this.

We write coverage on transactions and not on signals in most of the cases.
