# 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. |
