-map_layer layer_mapping_file_name
Specifies the file that defines the layer mapping from Milkyway to GDSII.
The layer mapping file format is
MWObjType[MWNetType][PinCode]
MWLayer[:MWDataType] GDSLayer [GDSDataType]
Valid values for MWObjType are
* A for all types
* T for text
* D for data
Valid values for MWNetType are
* A for all types
* S for signal
* P for power
* G for ground
* C for clock
* U for up conduction layer (upper layer in a via)
* D for down conduction layer (lower layer in a via)
* X for power or ground wires or contacts with a "signal"
or "tie-off" routing type
Valid values for PinCode are
* P means that the pins on each CEL view cell being
processed, which might include child cells depending on
the value of the -child_depth option, are mapped
by this rule.
* T means that only the top-level pins (terminals) on the
current top-level cell are mapped by this rule.
* null
For example, to map the text associated with signal nets on Milkyway layer
10 with a data type of 20 to GDS layer 22 with a data type of 1, enter
TS 10:20 22 1
To map the geometry of METAL1 terminals to GDS layer 15:2 and map the geometry
of lower-level METAL1 pins (not terminals) to GDS layer 14:2, enter
DSP METAL1 14 2
DAT METAL1 15 2
By default, write_stream uses the layer information defined in the Milkyway
database. |
