modelling. [Couriersud] Added global NETLIST.DEFAULT_MOS_CAPMODEL parameter. Setting this to zero disables using capitance modelling in mos models. On a per mos device basis this can be achieved by adding CAPMODEL=0 to the model definition, e.g. MOSFET(X, "NMOS(CAPMODEL=0)") Improve MOSFET convergence by using log-stepping.
