1. Let environment (runscripts) to generate seed for you (system time
etc)
2. Write it to the separate file in results directory
3. Read this file in the beginning of simulation run to get the seed
(using for example $readmemh in verilog)

Next time, you have an option to replicate simulation, using the same
seed file. Otherwise, overwrite it with another seed value.
