mfactor Property

mfactor integer x_integer

Description

Defines a one-to-many parallel relationship between a device in a schematic and multiple instances of the device in the layout.

You cannot use multiplication factors with components that cannot be used in parallel, such as voltage sources.

The mfactor property and mfactorSplit environment variable both work hierarchically. Any instance in the connectivity source hierarchy can have these properties, and the multiplicity is computed from the hierarchical path.

You can use the mfactorSplit environment variable to control whether the mfactor produces multiple layout devices or not. You can also use the lxMfactorSplit Property property on a given instance to override the global value given by the mfactorSplit environment variable.

Naming Convention

Devices specified using the mfactor property in the schematic (and those that are folded in the layout) are named instName.integer in the layout.

For example, if you have a schematic instance named P0 with

mfactor = 3

the layout instances generated are named as follows.

Schematic	Layout
`P0`	`\|P0.1 \|P0.2 \|P0.3`

Or, if the prefixLayoutInstNamesWithPipe environment variable is set to nil.

Schematic	Layout
`P0`	`P0.1 P0.2 P0.3`
