Physical Verification
Verifies the layout satisfies all foundry manufacturing rules (spacing, width, enclosure, density). Zero DRC violations required for tape-out. Tool: Calibre DRC
DRC - Design Rule Check
Verifies the layout satisfies all foundry manufacturing rules (spacing, width, enclosure, density). Zero DRC violations required for tape-out. Tool: Calibre DRC, Mentor.
LVS - Layout vs Schematic
Compares extracted netlist from layout with the reference schematic. Verifies all connections are correct and no opens/shorts were introduced during PD. Tool: Calibre LVS.
ERC - Electrical Rule Check
Checks for floating nodes, unconnected power/ground, improper biasing, ESD violations, latchup risk areas. Ensures circuit will function correctly electrically.
