Glitch Free Combinational Clock Gating Approach in Nanometer VLSI Circuits

Project Code :TVMAFE182

Abstract

Low power design is gaining prominence due to the increasing need of battery operated portable devices with high computing capability. It is the critical issue in ASIC design, as featured size is scaled down. The reliability of integrated circuit depends on the heat dissipated in the circuit. A large fraction of the power consumed is due to the clock distribution network and the high switching activity at the nodes. Clock Gating is the well-known power-saving technique used to reduce the clock power. To save power, clock gating refers to triggering the clocks in a logic block only when there is work to be done. Every unit on the chip has a power reduction plan, and almost every Functional Unit Block (FUB) contains clock gating logic. In this paper, we explain the way of Glitch reduction for ISCAS 85 bench mark circuits using combinational clock gating principle. The functionality of bench mark circuits are verified using Xilinx   with RTL compiler.
