Hi, I am using ncvhdl, ncelab, and ncsim to perform some VHDL simulations. I would like to know if doing the following would cause problems with the simulations: [QUOTE] ncelab -generic [one set of parameters] my_configuration ncsim my_configuration & ncelab -generic [another set of parameters] my_configuration ncsim my_configuration &[/QUOTE] I.e. can I elaborate the design, start simulating that, re-elaborate it with different parameters, and start another simulation in parallel? Will this cause any problems or inconsistencies?
