Hardware Acceleration of Gate Array Layout
Philip M. Spira, Carl Hage · Design Automation Conference · 1985
In this paper we describe the hardware and software of a system which we have implemented to accelerate the physical design of gate arrays. In contrast to nearly all other reported approaches, our approach to hardware acceleration is to augment a single-user host workstation with a general-purpose microprogrammable slave processor having a large private memory. One or more such slaves can be attached. We have implemented placement improvement on the system, achieving a 20 x speedup vs. a high-level host implementation. We give performance results, which are comparable to those reported elsewhere for mainframe implementations.
