Digital logic chips synchronize all logic operations by using a clock signal connected to flip-flops or latches, and the clock is distributed across the entire chip. The ultimate goal is to have a clock signal that arrives at the exact same moment in time at all clocked elements. If the clock arrives too early or too late from the PLL… Read More

White Paper: A Closer Look at Aging on Clock Networks
We all know that designers work hard to reach design closure on SOC designs. However, what gets less attention from consumers is the effort that goes into ensuring that these chips will be fully operational and meeting timing specs over their projected lifetime. Of course, this is less important for chips used in devices with projected… Read More
Unexpected Help for Simulation from Machine Learning
I attend a lot of events on machine learning and write about it regularly. However, I learned some exciting new information about machine learning in a very surprising place recently. Every year for the last few years I have attended the HSPICE SIG dinner hosted by Synopsys in Santa Clara. This event starts with a vendor fair featuring… Read More
Multi-Level Debugging Made Easy for SoC Development
An SoC can have a collection of multiple blocks and IPs from different sources integrated together along with several other analog and digital components within a native environment. The IPs can be at different levels of abstractions; their RTL descriptions can be in different languages such as Verilog, VHDL, or SystemVerilog.… Read More
Maybe Clockless Chip Design’s Time has Come
There have always been novel technologies vying to compete with conventional design practices. It is hit or miss on the success of these ideas. In the 90’s I recall speaking to someone who was convinced that they could effectively build computers based on multilevel logic. This, as we know did not pan out. But there have been many … Read More
Expert Tool to Easily Debug RTL and Reuse in SoCs
SoC design these days has become a complex and tricky phenomenon involving integration of multiple IPs and legacy RTL code which could be in different languages, sourced from various third parties across the globe. Understanding and reusing RTL code is imperative in SoC integration which needs capable tools that can accommodate… Read More
CEO Interview: Jason Xing of ICScape Inc.
I recently had the opportunity to interview Jason Xing, Ph.D., CEO and President of ICScape, Inc. Below is a subset of the nearly two hour long interview.
How did you first become involved in EDA?
My EDA career started in the mid-90s when I started working on my PhD thesis at the University of Illinois in Urbana-Champaign. My thesis… Read More
