Overview

Expertimental system to get optimum placement in standard cell LSI design

Features

This experimental system is constructed to examine the efficiency of parallel processing applied to LSI design problems and to search and develop a parallel algorithm.

The Parallel Simulated Annealing(SA) algorithm, developed by ICOT, is adopted to obtain optimum configurations. Parallel SA is obtained by expanding sequential SA that are known to solve the combinatorial optimization problem.

Configuration

Functions

Decides the physical position of each cell in standard cell LSI design with the aim to minimize the total estimated wire length in the chip.
Displays the result cell placement graphically and also the estimated value and approximate channel density.
Parameters can be set to arbitrary values to search and examine the performance of parallel SA algorithm.
Monitors the procedure of parallel SA by displaying the energy on a line graph.
Suspension and the re-execution can be done if necessary, and allow the user to edit a placement using the graphic interface.
