First of all, it's the MMSIM version that matters here, not the IC version. Given the level of detail you've provided, I would suggest: Make sure you're using MMSIM14.1 or MMSIM15.1 (or at a pinch, MMSIM13.1 Update release or later - so you'd have 13.1.1 in the simulator version) In the Setup->Environment in ADE add +diagnose onto the userCmdLineOption field. This will print detailed diagnostics as to what might be causing the timestep issues. Yes, under Setup->High Performance Simulation you can turn on "APS" which is the Accelerated Parallel Simulator option for spectre. That won't necessarily solve your convergence problems though (it might, but it most likely is something you need to diagnose carefully). Usually it's a circuit (or sometimes a model) problem.
