Recursive Function Smoothing of Half-Perimeter Wirelength for Analytical Placement

Abstract

Inspired by recent success of analytical placers that use a logarithm-sum-exponential (LSE) to smooth half-perimeter wirelength (HPWL), the authors consider in this paper two alternative smoothing methods for HPWL by recursive extension of two-variable max functions. A limited memory quasi-Newton solver is applied to solve the objective function combining… (More)
