Solido Extracting capacitance of all nodes

.OPTION CAPTAB prints in the ASCII .chi output file the capacitance values which are placed in the AC matrix.

With AMSV 2023.1 and later releases, it is possible to extract capacitance of all nodes by using the following two commands:

.OPTION CAPTAB
.EXTRACT -R CAP_CTOT(*)

Combining these commands with .TRAN and .OP TIME= allows to extract all the nodes capacitance at a specific time.

Note

.option CAPTAB is not supported with ELDO PREMIER. Eldo will issue the following warning:

Warning 90: .OPTION CAPTAB is not supported with Premier.

and for each node in the circuit, the following message:

CAP_CTOT(<node>) cannot be measured. Check your input netlist.
Specifying the type of analysis might solve the problem.

You can experiment with this new syntax in AMSV 2023.1 and later releases downloading and using the small testcase KB000073495.tgz, derived from the Eldo example ram8k.cir.
