place_cell¶
Synopsis¶
% place_cell -inst_name <inst_name> \
[-cell <library_cell>] \
-origin <point>] \
-orient (R0|R90|R180|R270|MX|MY|MXR90|MYR90) \
[-status (PLACED|FIRM)]
Description¶
Use the place_cell command to place an instance at a specific location within the design. This can be used to pre-place marker cells, ESD cells, etc. which have a known, fixed location in the design and should not be moved by the automatic macro placer.
One of the -inst_name, -origin and -orient options is required. If there is no instance <inst_name> in the netlist of the design, then the -cell option is required, and an instance of the specified <library_cell> will be added to the design. If an instance <inst_name> does exist in the design and the -cell option is specified, it is an error if the instance in the netlist does not match the specified <library_cell>.
Options¶
