Application of error diagnosis technique to incremental synthesis
In an LSI design process, Engineering Change Orders (ECO's) are often given even after the layout process. This letter presents an approach to change the design to satisfy the new specification with ECO's by employing an error diagnosis technique. Our approach performs incremental synthesis using spare cells embedded on the original layout. Experimental results show that applying the error diagnosis technique to incremental synthesis is effective to suppress increase in delay time caused by ECO's.
