Description<br />

Sets the charge error tolerance when<br />

LVLTIM = 2 is set.<br />

Capacitance added from each node to<br />

ground.<br />

Sets the maximum iteration-to-iteration<br />

current change through voltage defined<br />

branches (voltage sources and inductors).<br />

Sets the minimum conductance allowed<br />

for in a transient analysis time sweep.<br />

Conductance added from each node to<br />

ground.<br />

Sets the maximum current through<br />

voltage defined branches (voltage<br />

sources and inductors).<br />

Sets relative current tolerance through<br />

voltage defined branches (voltage<br />

sources and inductors).<br />

Sets the relative error/tolerance change<br />

from iteration to iteration to determine<br />

convergence for all currents in diode,<br />

BJT, and JFET devices.<br />

Used in the local truncation error<br />

timestep algorithm (LVLTIM = 2).<br />
