Recognition of logic blocks in CMOS circuits
… technique to divide a given circuit into smaller subcircuits. This is followed by the extraction of logic expressions at the output nodes of subcircuits. From these logic expressions, gates are recognized. Functional blocks in the circuit are recognized based on rules which define such blocks in …
