Each of these actions apply to a specified set of nets. <arg>net</arg> and <arg>pin</arg> are patterns which match one or more nets or pins; these patterns may be full names or regular expressions. If an exact match is found, it is the only match; if no exact match is found, then the pattern is tried as a regular expression.

If neither <arg>net</arg> nor <arg>pin</arg> are specified, all nets apply. If <arg>net</arg> is specified but not <arg>pin</arg>, all nets matching <arg>net</arg> apply. If both are specified, nets which match <arg>net</arg> and contain a pin matching <arg>pin</arg> apply.

<arg>freeze</arg>, <arg>thaw</arg> and <arg>forcethaw</arg> temporarily prevents changes to the netlist from being reflected in the GUI. For example, if you need to make multiple changes, you <arg>freeze</arg> the netlist, make the changes, then <arg>thaw</arg> it. Note that freeze/thaw requests may nest, with the netlist being fully thawed only when all pending freezes are thawed. You can bypass the nesting by using <arg>forcethaw</arg>, which resets the freeze count and immediately updates the GUI.
