transistorWidthParamNames

layoutXL transistorWidthParamNames string "list_of_parameters"

Description

Lists the names of the schematic parameters used to specify transistor width.

The default is "w".

The transistor width value must be split among the generated parallel-connected devices during the following Connectivity commands.

Generate All From Source
Check Against Source
Update Layout Parameters.

Layout XL checks each schematic instance for one of the listed parameter names and updates the width values of the matching layout parameters such that

number of mfactored instances * mfactorSplit value = source parameter value

For cyclic split parameters, if the exact value is not matched, the closest value will be used instead.

This environment variable is also used by the Module Generator when adding dummy devices to MOSFETs or resistors with the modgenMakeMinDummies environment variable set to t.

Arguments

list_of_parameters

A list of parameter names each separated by a space. The list must be enclosed in quotation marks; for example,

"w"
