9. Physical Design Verification

Physical design verification plays a crucial role in the VLSI design process by ensuring that the physical layout of a chip meets design specifications and manufacturing rules. Key methods include Design Rule Checking, Layout Versus Schematic, and Electrical Rule Checking. The tape-out process, which involves generating GDSII files, marks the transition from design to fabrication and requires final verifications to prevent costly manufacturing errors.
