Description<br />

Used to convert DC model and element<br />

capacitors to a conductance to enhance<br />

DC convergence properties.<br />

DCTRAN is an alias for CONVERGE.<br />

See CONVERGE.<br />

The maximum iteration-to-iteration<br />

voltage change for all circuit nodes in both<br />

DC and transient analysis.<br />

The conductance in parallel with the<br />

current source used for .IC and<br />

.NODESET initialization conditions<br />

circuitry.<br />

A conductance that is placed in parallel<br />

with all pn junctions and all MOSFET<br />

nodes for DC analysis.<br />

Value is set by <strong>Star</strong>-<strong>Hspice</strong> during the<br />

autoconvergence procedure.<br />

Conductance added from each node to<br />

ground.<br />

For a parameter or temperature sweep,<br />

saves the results of the current analysis for<br />

use as the starting point in the next<br />

analysis in the sweep.<br />
