RIM: Routing Into Macrocells and application to an arithmetic processor

Abstract

This paper presents first a silicon assembler and then a router. The two programs have to be described together since the router uses tracks, terminals and obstacles that are build by the assembler. Using tracks that run inside the macrocells dramatically reduces the area demanded for routing. An example of assembling and routing of a mathematicalfunctions processor [1,2,3] is provided at the end of the paper.
