Webb24 maj 2024 · A work-around I have done in Questa-Sim in the past is generating a random root seed R in a script/makefile, and then create necessary simulation folders corresponding to this generated seed. Finally, invoke the simulation command from the script, and pass R as argument using -sv_seed R flag. Share Cite Follow edited May 25, … WebbSystemVerilog has randomize(),pre_randomize() and post_randomize() built-in functions for randomization. Calling randomize() causes new values to be selected for all of the random variables in an object. To perform operations immediately before or after randomization,pre_randomize() and post_randomize() are used. Randomize() don\u0027t work on vacation
