Thank you Dave.
In Verilog I used currenttime as an input seed to $random
$random(currenttime); That is why I have to save the currenttime as seed.txt
In SystemVerilog if we pass a constant seed as runtime to $urandom(constant seed)
everytime when we run the simulation, only same set of random numbers are generated
Whereas if we use currenttime as seed, different random numbers are generated
at different runs. If we want this way even in SystemVerilog we have to
save the currenttime as seed.txt
Is there any better way to manage the seed, other than saving the seed as seed.txt
in simulation ?
We may need to pass different seed value as runtime argument if we want different random numbers.
