hello experts, we are playing Spectre simulator with very high precision circuits so naturally we need very tight tolerance setting, e.g., 'reltol 1e-6 'vabstol 1e-8 'iabstol 1e-14. on the other side, the translated digital signals or testbench signals not necessary to work for this hard at all. with the simulation running, it's easily run into convergence problem due to this unnecessory tight digital signals or testbench signals. so wonder if I can set design dependent tolerance so that the real critical analog circuit works with tight tolerance, but not anything else? thanks, David
