NAME
extract_parasitics - extract parasitics
SYNOPSIS
extract_parasitics
[-ext_model_file filename]
[-corner_cnt count]
[-max_res ohms]
[-coupling_threshold fF]
[-debug_net_id id]
[-lef_res]
[-cc_model track]
[-context_depth depth]
[-no_merge_via_res]
DESCRIPTION
The extract_parasitics command performs parasitic extraction based on the
routed design. If there are no information on routed design, no parasitics are
returned.
OPTIONS
-ext_model_file: Specify the Extraction Rules file used for the extraction.
-corner_cnt: Defines the number of corners used during the parasitic extraction.
-max_res: Combines resistors in series up to the threshold value.
-coupling_threshold: Coupling below this threshold is grounded. The default value is 0.1, units are in fF, accepted values are floats.
-debug_net_id: Developer Option: Net ID to evaluate.
-lef_res: Override LEF resistance per unit.
-cc_model: Specify the maximum number of tracks of lateral context that the tool considers on the same routing level. The default value is 10, and the allowed values are integers [0, MAX_INT].
-context_depth: Specify the number of levels of vertical context that OpenRCX needs to consider for the over/under context overlap for capacitance calculation. The default value is 5, and the allowed values are integers [0, MAX_INT].
-no_merge_via_res: Separates the via resistance from the wire resistance.
