Abstract: A method for boundary port modelling that correctly handles back-to-back isolation intent, level shifter intent and voltage level association, by providing hard association of power domains to soft data objects, such as wires. The method includes identifying a boundary port in a detailed power intent (DPI) for a soft design object (SDO). A non-wire object is inserted in the SDO for the boundary port. In the DPI, a power domain of the boundary port is assigned to the non-wire object.
