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.
This fixes a rounding issue in the ptime code. This bug surfaced when I
tested netlist with picosecond resolution in ptime.
This will have a small impact on every driver using netlist. For
breakout, it required to adjust the color overlay.
