.OPTION CAPTAB
Adds up all the capacitances attached to a node and prints a table of singleplate
node capacitances.
Syntax
.OPTION CAPTAB
Default 0
Description
Use this option to print a compiled table of single-plate node capacitances for
diodes, BJTs, MOSFETs, JFETs, and passive capacitors at each operating
point.
Note:
When .OPTION CAPTAB is used to estimate the equivalent capacitance of
the circuit nodes, HSPICE can give a zero capacitance values for some
nodes when a resistance is connected to that node. The reason for getting
0 is that the capacitance is a dynamic, frequency-dependent capacitance
and not a static capacitance. You need to run an AC analysis to see a nonzero
node capacitance.
