lsSingleRailInputPrefix

lp lsSingleRailInputPrefix string "int_" 

Description

For a single rail cell in case the modeling information is coming from 1801 special cell definition file, it would not contain information of the attribute input_signal_level corresponding to the liberty model. A virtual supply name, with the prefix int_, will be created from output supply of the single rail level shifter. The data ports of the single rail level shifter would thus be related to a supply set containing the virtual supply name and the name of the ground supply as related power and related ground.
