Abstract
A system for identifying and bounding the regions of a digital electronic logic design model that are affected by design revisions. The system is useful for improving the efficiency of incremental logic synthesis systems and includes procedures for recording the signals directly affected by user revision operations and for marking signals in the logic to identify those indirectly affected. A smart editor capable of parsing the formal register transfer language (RTL) in which the logic design is described is included in the system.
