Architectures and CAD Tools for 3D FPGAs

Architecture-Level Exploration of Alternative Interconnection Schemes Targeting 3D FPGAs: A Software-Supported Methodology

In current reconfigurable architectures, the interconnection structures increasingly contribute more to the delay and power consumption. The demand for increased clock frequencies and logic density (smaller area footprint) makes the problem even more important. Three-dimensional (3D) architectures are able to alleviate this problem by accommodating a number of functional layers, each of which m...

On Biased and Non-Uniform Global Routing Architectures and CAD Tools for FPGAs

This paper is organized as follows

As Field-Programmable Gate Array (FPGA) power consumption continues to increase, lower power FPGA circuitry, architectures, and Computer-Aided Design (CAD) tools need to be developed. Before designing low-power FPGA circuitry, architectures, or CAD tools, we must first determine where the biggest savings (in terms of energy dissipation) are to be made and whether these savings are cumulative. I...

Issues of Wirelength Cost Models in Routing-Constrained FPGAs

Contrary to prevailing consumer conceptions of efficient silicon use, previous research efforts have shown that designing routing-poor FPGAs may yield significant area gains. In this paper we show that conventional wirelength-centric placement tools are unable to deal with the challenges that routing-limited CAD problems present. We believe that this problem is present given today’s architectur...

Realizing Low Power FPGAs: A Design Partitioning Algorithm for Voltage Scaling and A Comparative Evaluation of Voltage Scaling

With an exponential rise in logic density and performance, FPGAs are becoming essential components in various electronic systems. However, increased logic density and more importantly programmability of FPGAs cause increased power dissipation, which limits deployment of FPGAs in power constrained consumer electronic products such as mobile systems. Voltage scaling is a well-known tool to reduce...
