i have to do coverage for 64 bit value parameter, but as i know specman doesn't support for 64 bit value  parameter coverage. please suggest me if any constuct are there to 64 bit value coverage.

  • Presumably you only care about certain ranges of values for your 64-bit field, so perhaps you can split the coverage into 2 or more different items that cover those ranges of interest? Here's an example:

    extend sys {
      a64 : uint(bits:64);
      event ev;
      cover ev is {
        item a1 : uint(bits:8) = a64[63:54];
      };
    };
