vfpPowerWireTypes

layoutXL.floorplan vfpPowerWireTypes string "((layerName|All (wireType|none)))"

Description

Defines the mapping between nets of signal type "power" and a wire type track. You can specify multiple pairs of metal layer and wire type tracks on which power net pins are to be placed during pin optimization.

• layerName refers to specific layer names. Type All to indicate all metal layers.
• wireType refers to the wire type track name defined in the technology file. Type none to indicate tracks of type "no wireType".

The default value is "".

None

Examples

envGetVal("layoutXL.floorplan" "vfpPowerWireTypes")

envSetVal("layoutXL.floorplan" "vfpPowerWireTypes" 'string "((All (vss)))")

In the above example, all pins on the power nets move to the "vss" track for all metal or poly layers after pin optimization.

envSetVal("layoutXL.floorplan" "vfpPowerWireTypes" 'string "((Metal2 (vss)) (Metal3 (vsse)) (Metal4 (vss)))")

In the above example, all pins on the power nets move to the "vss" track if the pin is on Metal2 or Metal4 layer, and move to the "vsse" track if the pin is on Metal3 layer after pin optimization.

envSetVal("layoutXL.floorplan" "vfpPowerWireTypes" 'string "((Metal1 (none)))")

In the above example, all pins on the power nets move to the "no WireType" wire type track if the pin is on Metal1 layer after pin optimization.
