Description
Runs the ART spine generator and the spine router together.
Arguments
|
d_cvid
|
Database ID of the cellview. Can be obtained using the geGetEditCellView SKILL function.
|
|
layers l_layers
|
A list of routing layers.
|
|
spineLayer t_spineLayer
|
|
|
Specifies a spine layer.
|
|
createSpineSettings g_createSpineSettings
|
|
|
A DPL that specifies the settings for creating spines list.
list( nil 'enable nil|t)
|
|
routeSpineSettings g_routeSpineSettings
|
|
|
A DPL that specifies the settings for routing pins to spines.
list( nil 'enable nil|t
'twigSharingDist nil|value
'maxJogLength nil|value
'spinePinMaxDist nil|value
)
|
|
?nets l_nets
|
A list of net names to be routed. If no net 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 on which the function should operate.
|
|
?preferredLayers l_preferredLayers
|
|
|
A list of preferred routing layers.
|
|
?viaCost f_viaCost
|
The cost that the routing algorithm uses when considering creating a via. If the cost is 1, each via’s cost is equivalent to that of a pathseg with the same length and track width. If set to nil, the cost is determined by the routing algorithm.
|
|
?connectBothGates g_connectBothGates
|
|
|
Forces nets to connect to all the pins on the same poly gate, or to allow only one connection per gate.
|
|
?preferVio2Open g_preferVio2Open
|
|
|
Determines whether the router should generate wires with constraint violations or instead leave them unrouted. This is for the wires that cannot be routed without violation.
|
|
?postFixTrim g_postFixTrim
|
|
|
Automatically adds trim shapes to routed nets to fix end-of-line (EOL) constraint violations.
|
|
?postFixMinLength g_postFixMinLength
|
|
|
Automatically extend routed pathseg and via shapes to satisfy various min length constraints, such as minLength, minArea, minRectArea, etcetera.
|
|
?postFixEolKeepout g_postFixEolKeepout
|
|
|
Determines whether or not to fix end-of-line keepout DRC violations after routing.
|
Value Returned
|
t
|
Spine generation and routing was successful.
|
|
nil
|
Spine generation and routing failed.
