This is part of the "LSCS" infrastructure - the netlisting and simulation are separated into different processes, which allows better management of the resources (netlisting requires a background virtuoso, whereas simulation doesn't need a virtuoso sitting around consuming memory whilst the simulation runs). With single jobs, there's "single job optimisation" turned on in most cases and so the netlisting is done in the foreground - when you have multiple points, it always starts a background process to run netlisting. You didn't mention which IC sub-version you're using - this will be in the Help→About menu. Does it work if you change to "ICRP" on the Job Policy form? Can you run (from the command line) "virtuoso -nograph" ? Regards, Andrew
