IC Layout and Connection Workflow with Cadence: From Architecture to Verification

The Cadence VLSI Placement and Routing (PnR) workflow encompasses a comprehensive suite of tools, enabling designers to transition from initial architectural architecture to final silicon closure. It typically begins with abstract floorplanning, where macro blocks and IP blocks are strategically positioned to optimize area, timing, and power. Following floorplanning, detailed placement algorithms within Cadence's Innovus or Tempus tools iteratively minimize wirelength and congestion, frequently incorporating design-for-manufacturing (DFM) considerations at an early stage. Routing then proceeds, establishing electrical connections between placed components, with Cadence’s VoltSure addressing electromigration and junction integrity. This includes handling advanced packaging and heterogeneous integration scenarios. Timing analysis and optimization—a crucial, iterative step—is continually performed alongside placement and routing to ensure the design meets strict frequency and setup time requirements. Post-route, physical verification checks—Verification, Matching, and parasitic modeling—are executed. Ultimately, the complete flow culminates in closure, ensuring a manufacturable design ready for tapeout, incorporating stringent industry standard compliance checks and quality assurance protocols.
