The !fc Command: Control Capacitance Extraction Interface

Syntax: !fc keyword [arg ...]

This command is a prompt-line equivalent to some of the functionality of the capacitance extraction interface described in 16.17.1. This interface is also controlled from the Cap Extraction panel, which is produced by the Extract C button in the Extract Menu.

The first argument is a keyword, which must be present and must be one of those listed below. Additional arguments are specific to the keyword. The keywords perform an operation that is equivalent to pressing one of the buttons in the Cap Extraction panel.

dump [filename]
This will dump a unified list file using the name given in the argument, or the default name if no name is given. The default name is the name of the current cell with a ``.lst'' suffix.

This is equivalent to pressing the Dump Unified List File button in the Run page of the Cap Extraction panel. The format is compatible with the FasterCap program from FastFieldSolvers.com, and also the Whiteley Research version of FastCap, the latter requires use of the FcPanelTarget variable.

run [-i infile] [-o outfile] [-r resultfile]
If an infile is specified, that file will be taken as input to the capacitance extraction program, as if the Run File button in the Run page of the Cap Extraction panel was pressed and the infile specified in the text input area. Otherwise, the action is as if the Run Extraction button was pressed instead.

The outfile is the file used for standard output from the extraction program during the run. If not given, a temporary file will be used, and destroyed when the run completes, after copuying the content to the results file. If a name is provided, that file name will be used, and the file will not be destroyed.

If no name is given for the resultfile, a default name will be used. This file will contain input to and output from the extraction run.
