NAME

circuit - Tool to examine circuits.

SYNOPSIS

circuit [options] [--] cell sub-command arg1 ... argN

OPTIONS

-h, --help

Display a help message.

-v, --verbose

Turn on verbosity.

--no-color

Disable colored output.

DESCRIPTION

The circuit tool allows the user to examine a circuit in various ways. The circuit may have been generated by space(1ICD), for example, or it may have been entered manually using csls(1ICD).

The first (fixed) argument to circuit is always the name of the cell that is to be examined. This cell (obviously) should have a circuit representation in the database (you can check this by typing dblist -c).

The second (fixed) argument to circuit is the sub-command. The following sub-commands are available.

circuit cell adjacent NODE

The adjacent sub-command allows the user to list the nodes connected to a given node NODE. Please see the manual entry for circuit-adjacent(1ICD) for more details.

circuit cell admittance script

The admittance sub-command allows the user to determine the two-port admittance matrix for two given nodes in a network. Please see the manual entry for circuit-admittance(1ICD) for more details.

EXAMPLE

The following example shows how to obtain the (names of the) nodes adjacent to the given node named "SUBSTR".

    # circuit -v oscil adjacent SUBSTR
