hi... i have asn assignment in apb slave dut. i read the apb amba specification. i have a doubt what could be the test cases used here? according to me i feel pwdata, pwrite, prdata and pready are the test cases. here we are giving the values for penable, psel and paddr is already defined. so is my observation correct?
I'm sorry but I don't understand what you are asking. What do you mean by "test cases" ?
PWDATA, PWRITE, PRDATA and PREADY are signals, not "test cases".
Are you trying to test something, and don't understand how to use the signals, or are you trying to test the APB protocol itself (and if so, why) ?
