Abstract: As the chip manufacturing process is approaching the physical limits, multidie stacked 3DIC Chiplets design has become one of the best ways to continue Moore's Law. Integrity 3D-IC platform integrates design planning, physical implementation, and systematic analysis into one single management interface, providing a comprehensive solution for 3DIC design. In conventional die-by-die flow, after 3D structure is established,two or more dies are implemented phsically and independently. Besides, the tool supports concurrent multidie implementation flow with placement and routing simultaneously in two dies. This work uses Cadence Integrity 3D-IC to establish concurrent multidie implementation flow, including parallel two-die placement , 3D unit (Hybrid Bonding bump) position optimization, clock tree synthesis and routing. The results show the comprehensive performance of concurrent PnR flow is better than die-by-die flow.
