ABSTRACT:
A computer aided design tool and method for designing IC layouts by recommending subcircuit layout constraints based upon an automated identification from a circuit schematic of subcircuit types requiring special IC layout constraints. Subcircuit types are identified on the basis of netlist examination, as well as cues from the layout of the circuit schematic.
