autoAbutment
layoutXL autoAbutment boolean { t | nil }
Description
Turns on automatic abutment, which abuts prepared transistors so that they can share pins. Abutment is switched on for both automatic and interactive layout generation and during automatic placement using the Virtuoso custom digital placer.
The default is t, which means that devices that have not been abutted but are overlapping can be abutted. If the devices are already abutted, they are not reabutted.
Auto-abutment works only when automatic extraction is on, when the
extractEnabled environment variable is set to t.GUI Equivalent
Examples
envGetVal("layoutXL" "autoAbutment")
