Charge Conservation Parameters (CAPOP=4)<br />

Name (Alias) Unit Default Description<br />

MOSFET Element Statement<br />

XQC - 0.5 Coefficient of channel<br />

charge share attributed<br />

to drain<br />

See “Using Charge Conservation Parameters (CAPOP=4)” in<br />

the <strong>Star</strong>-<strong>Hspice</strong> Manual.<br />

Gate Capacitance CAPOP=5<br />

Use CAPOP=5 for no capacitors and HSPICE will not<br />

calculate gate capacitance. For detailed information, see<br />

“Defining CAPOP=5 — Gate Capacitance” in the <strong>Star</strong>-<strong>Hspice</strong><br />

Manual.<br />
