Tcl Format

The most important part to take note of are: sta::define_cmd_args - which defines what is printed when a user types help command in the OR shell; as well as sta::parse_key_args - which defines what keys/flags the command actually parses.

Let us use check_antennas command for an example.

Specification

sta::define_cmd_args "check_antennas" { [-verbose]\
                                          [-net net]}

proc check_antennas { args } {
  sta::parse_key_args "check_antennas" args \
    keys {-report_file -net} \
    flags {-verbose -report_violating_nets}
...
}

Do not compile

If you add ;# checker off behind the command’s sta::define_cmd_args {} and sta::parse_key_args {} the function will not be compiled in the Manpages and included in the doctests.

sta::define_cmd_args "check_antennas" { [-verbose]\
                                          [-net net]} ;# checker off

proc check_antennas { args } {
  sta::parse_key_args "check_antennas" args \
    keys {-report_file -net} \
    flags {-verbose -report_violating_nets};# checker off
...
}
