Note:
If the hierarchical antenna properties are not defined for all layers for a macro, Zroute
treats the data as incomplete, skips antenna analysis, and issues a ZRT-311 warning
message. If you get this error message, see SolvNet article 027178, “Debugging the
ZRT-311 Message.”
route.detail.default_gate_size
Specifies the gate size used for pins during antenna analysis if the gate size is not specified in the frame
view of the cell.
TYPE
float
DEFAULT
-1.0
DESCRIPTION
This application option specifies the gate size used for pins during antenna analysis if the gate size is not
specified in the frame view of the cell.
The range is from -1.0 to 1,000,000.00. The unit is the square of the unitLengthName specified in the
technology file.
The tool uses this option only when you set it to a value of 0.0 or greater and the frame view does not
specify the gate size for the pin. This option has no effect when the frame view specifies a gate size
value.
