Filter expressions

The following commands support filtering returned objects by property values: get_cells, get_clocks, get_lib_cells, get_lib_pins, get_libs, get_modes, get_nets, get_pins, get_ports, get_scenes, and get_timing_edges.

Supported filter expressions are shown below.

Expression	Description
property	Return objects with property value equal to 1.
property==value	Return objects with property value equal to value.
property=~pattern	Return objects with property value that matches pattern.
property!=value	Return objects with property value not equal to value.
property!~pattern	Return objects with property value that does not match pattern.
expr1&&expr2	Return objects that match expr1 and expr2.
expr1||expr2	Return objects that match expr1 or expr2.

Where property is a property supported by the get_property command. If there are spaces in the expression it must be enclosed in quotes so that it is a single argument.
