hspice capacitance

I heard there is some options can be set to do.

Added after 22 minutes:

In HSPICE manual, it says options captab can help. I used it, but nothing happened. Anybody can tell me?
 

hspice captab

use cap(node) instruction and AC sweep
if does not work i have another idea.

captab hspice

Could explain more? I don't understand.
Or could tell me which chapter in hspice manual I can find.

Thanks a lot
 

.option captab

Indeed,my simulation result is also no responce when I add option cadtab.
Maybe our Hspice version do not support it??
 

hspice node capacitance

hi
in "hspice_sim_analysis.pdf" (hspice 2004 user manual)
page 309 (7-25)

Nodal Capacitance Output
SYNTAX:
CAP(nxxx)
For nodal capacitance output, HSPICE prints or plots the
capacitance of the specified node nxxxx.
EXAMPLE:
.print ac CAP(5) CAP(6)
 

hspice capacitance information

cap() is so good
much better than captab
 

hspice captap

.option captap,and see the output file
 

spice option captab

as jinxingsun said,in .option line add this: "Captab",then in output .lis file ,hspice will list the cap of each node
