lxSeriesTerms Property

lxSeriesTerms string t_terminal_name

Description

Specifies the connectivity of schematic and lxCombination devices with sfactor greater than 1 and instance terminals greater than 2. Set this property on the schematic instance.

The Split mfactored devices option must be turned on in the Generation of the Connectivity form.

The environment variable does not support more than two terminals in series. To connect more than two terminals, expand them in the schematic and connect them in series or use a schematic Pcell to generate the series.

Cadence recommends that this property be set in the PDK. For some reason, if you set this in the middle of a Virtuoso session, it is recommended that you set Update Connectivity Reference Form to None and then again set to the schematic for the property to take effect.
