?name s_name
|
Name of the scheme. Value is a quoted symbol.
|
|
?ringAtCenter g_ringAtCenter
|
|
|
Routes a ring between the core area of the design and the surrounding pad instances. Values are t or nil. If nil, the ring is routed according to the setting of the ?relativeTo argument.
If no value is specified, uses the value of the prouteCoreRingAtCenter environment variable.
|
|
?relativeTo s_relativeTo
|
|
|
The location of the ring is relative to the specified location.
The values are the following:
‘insideIOPads
‘outsideCore
‘insideRegion
‘outsideRegion
With insideRegion or outsideRegion, also specify the region using the ?areaX/YLo and ?areaX/YHi arguments.
You must also specify a positive, non zero clearance using one of the following four arguments.
If no value is specified, uses the value of the prouteCoreRingRelativeTo environment variable.
|
|
?coreClearance f_coreClearance
|
|
|
Use when ?relativeTo is set to ‘outsideCore. Value is a positive, non zero floating number.
If no value is specified, uses the value of the prouteCoreRingCoreClearance environment variable.
|
|
?padClearance f_padClearance
|
|
|
Use when ?relativeTo is set to ‘insideIOPads. Value is a positive, non zero floating number.
If no value is specified, uses the value of the prouteCoreRingPadClearance environment variable.
|
|
?inAreaClearance f_inAreaClearance
|
|
|
Use when ?relativeTo is set to ‘insideRegion. Value is a positive, non zero floating number.
If no value is specified, uses the value of the prouteCoreRingInAreaClearance environment variable.
|
|
?outAreaClearance f_outAreaClearance
|
|
|
Use when ?relativeTo is set to ‘outsideRegion. Value is a positive, non zero floating number.
If no value is specified, uses the value of the prouteCoreRingOutAreaClearance environment variable.
|
|
?areaXLo f_areaXLo
|
Use to specify the region if ?relativeTo is set to either ‘insideRegion or ‘outsideRegion. Value is a floating number that must be within the prBoundary of the design.
If no value is specified, uses the value of the prouteCoreRingRTXLo environment variable.
|
|
?areaYLo f_areaYLo
|
Use to specify the region if ?relativeTo is set to either ‘insideRegion or ‘outsideRegion. Value is a floating number that must be within the prBoundary of the design.
If no value is specified, uses the value of the prouteCoreRingRTYLo environment variable.
|
|
?areaXHi f_areaXHi
|
Use to specify the region if ?relativeTo is set to either ‘insideRegion or ‘outsideRegion. Value is a floating number that must be within the prBoundary of the design.
If no value is specified, uses the value of the prouteCoreRingRTXHi environment variable.
|
|
?areaYHi f_areaYHi
|
Use to specify the region if ?relativeTo is set to either ‘insideRegion or ‘outsideRegion. Value is a floating number that must be within the prBoundary of the design.
If no value is specified, uses the value of the prouteCoreRingRTYHi environment variable.
|
|
?horiLayer t_horiLayer
|
The horizontal metal layer to use to route the core ring. Value is a layer string.
If no value is specified, uses the value of the prouteCoreRingHorizLayer environment variable.
|
|
?vertLayer t_vertLayer
|
The vertical metal layer to use to route the core ring. Value is a layer string.
If no value is specified, uses the value of the prouteCoreRingVertLayer environment variable.
|
|
?latticeStyle g_latticeStyle
|
|
|
Extend duplicate net segments to or from a lattice. Values are t or nil. If set to nil, the segments are concentric.
If no value is specified, uses the value of the prouteCoreRingLatticeStyle environment variable.
|
|
?netClearance f_netClearance
|
|
|
The minimum clearance between any two power nets. Value is a positive, non-zero floating number.
If no value is specified, uses the value of the prouteCoreRingNetClearance environment variable.
|
|
?netWidth f_netWidth
|
The total width of the nets to be routed. Value is a positive, non-zero floating number.
If no value is specified, uses the value of the prouteCoreRingNetWidth environment variable.
