As semiconductor process technology becomes more advanced, physical effects such as wiring delay and voltage drop, electromigration, signal integrity, crosstalk and process variability have become much stronger and have a significant impact on the performance of the resultant design.
This presents a significant challenge for a traditional design flow that begins with front-end logical design and then proceeds to back-end physical design. If the front-end process doesn’t take into account the impact of back-end effects, there will be many iterations between front-end and back-end design. This results in a longer and more costly design process that impacts time-to-market for the end product.
A hyper-convergent design flow allows widespread and easy sharing of front-end and back-end data in a unified design process to address these challenges. The process of using late-stage information to inform decisions made early in the design process is called a shift-left approach.
