Webputed time steps to avoid setting small time steps before transient simulation start. •Allows HSPICE to take time steps no larger than (Tstop-Tstart)/20. • DELMAX automatically sets (Tstop-Tstart)/20 if there is no speciﬁc setting of DELMAX. The effect is that, for example, HSPICE can take larger time steps for ﬂat regions.

WebThen, in the first time step, the voltage source is set to the operating output voltage so an infinite current is drawn from it to charge the capacitor up to this operating voltage. The simulator cannot find a short enough time step to make this current finite, and a “time step too small convergence fail” message is issued. lady\\u0027s-thumb vx
