I am writing a random test with seed variable in system verilog.I want to run the same test with different seed so i want my sequence to be nondeterministic by seeding the $urandom function with an extrinsic random variable, such as the time of day. How can i know time of day in stytem verilog.
Perhaps you can generate the seed with a shell script, save it to a file, then read it in using $fread. Alternatively you could create your own PLI library that implements it.
