Abstract

In this paper, analytical models for predicting interconnect requirements in field-programmable gate arrays (FPGAs) are presented, and opportunities for three-dimensional (3-D) implementation of FPGAs are examined. The analytical models for two-dimensional FPGAs are calibrated by routing and placement experiments with benchmark circuits and extended to 3-D FPGAs. Based on system-level modeling, we find that in FPGAs with more than 20K four-input look-up tables, the reduction in channel width, interconnect delay and power dissipation can be over 50% by 3-D implementation.
