Description
Runs power routing on the nets in the design.
Arguments
|
d_cvid
|
Database ID of the cellview on which power routing is to be performed. The database ID can be obtained using the geGetEditCellView SKILL function. The default value is the cellview of the current window.
|
|
?nets l_nets
|
A list of net names on which power routing is to be performed. If no net list is specified, it routes all the nets in the cellview.
|
|
?region l_region
|
A list specifying the lower-left and upper-right coordinates of the region where power routing is to be performed. If no region is specified, all nets inside the PR boundary or cell boundary are considered.
|
|
?layers l_layers
|
A list of layers to perform power routing. If no layer is specified, power routing is performed on all layers.
|
|
?options l_options
|
List of objects for power routing. If no object list is specified, nothing is routed. The valid object types are: createPath, createVia, createPin, connectPin, createFigGroup, sharedTrack, postFixTrim, and postFixMinLength.
|
|
?sharedTrack g_sharedTrack
|
|
|
Boolean value to specify whether the power router share a same track to different power net.
|
|
?net2WireTypes g_net2WireTypes
|
|
|
Specifies the wire type location mapping for power nets.
|
|
?postFixTrim g_postFixTrim
|
|
|
Boolean value to specify whether to do a post trim patch fixing after power routing.
|
|
?postFixMinLength g_postFixMinLength
|
|
|
Boolean value to specify whether to do a post minLength drc error fixing after power routing.
|
|
?postFixEolKeepout g_postFixEolKeepout
|
|
|
Boolean value to specify whether to do a post end of line spacing drc error fixing after power routing.
|
|
?logFile g_logFile
|
Specifies the name of a log file in which router messages are captured.
|
|
?appendToLog g_appendToLog
|
|
|
Specifies that new messages are appended to the log file if it already exists. If set to nil, the existing file is overwritten.
|
Value Returned
|
t
|
Nets were power routed successfully without any errors.
|
|
nil
|
Routing was unsuccessful due to errors.
|
Examples
The following example runs the Power Route command on all the wires and vias between M1 and M2.
vrtPowerRoute(geGetEditCellView() ?layers '("M1" "M2") ?options '("createPath" "createVia"))
The following example inserts vias between M1 and M2 on vss and vdd net.
vrtPowerRoute(geGetEditCellView() ?nets '("vss" "vdd") ?layers '("M1" "M2") ?options '("createVia"))
The following example runs the Power Route command on all the PG nets to create wires and vias and create a figGroup from M1 to M3 inside PR boundary.
vrtPowerRoute(geGetEditCellView() ?region?geGetEditCellView()->prBoundary->bBox ?layers '("M1" "M2" "M3") ?options? '("cratePath" "createVia" "createFigGroup")))
