With the improving evolution in VLSI technology most of the digital circuits are becoming SOCs. However most of the SOC systems are synchronous designs and the issues like clock skew, power consumption and EMI are related to clock network. Asynchronous circuits can offer benefits like reduced power and improved performance. However implementing whole design with asynchronous design style is a challenge...
In today's nanometric VLSI designs achieving both power and performance targets is the top most priority for design closure. Globally asynchronous locally synchronous (GALS) architectures can offer less dynamic power and improved performance due to absence of global clock. In GALS SoC architectures each synchronous blocks runs on their local clocks. Synchronous blocks communicate with each other by...

A glitch compensation methodology is proposed in this paper which involves reducing the undesired switching of selected combinational cells from a place and routed standard cell layout in order reduce peak dynamic voltage or IR drop. The proposed methodology can be seamlessly integrated to existing physical design flow. A glitch is an undesired transition that occurs before intended value in digital...
As the technology continues to shrinks, leakage power is growing at exponential rate due to the aggressive scaling trends of channel lengths, gate oxide thickness, and doping profiles combined with an increasing number of transistors packaged in a single chip. During the physical implementation stages VLSI designs often needs be corrected due to the changes in specification or design rule constraints...
A glitch compensation methodology is proposed in this paper which involves in reducing the undesired switching of combinational circuits in order to save dynamic power. The proposed methodology can be seamlessly integrated to existing physical design flow. A glitch is an undesired transition that occurs before intended value in digital circuits. A glitch occurs in CMOS circuits when differential delay...
