Since power has become a critical factor in semiconductor chip design, the stress is towards decreasing supply voltage to reduce power consumption. However, the threshold voltage to switch devices cannot go down beyond a certain limit and these results in an extremely narrow margin for noise between the two. And that gets further… Read More
Mission Critical Role of Unmanned Systems – How to fulfill?
Do we ever imagine what kind of severe challenges mission critical unmanned systems in air, land and underwater face? They are limited in space and size; have to be light in weight, flexible in different types of operations and at the same time rugged enough to work in extreme climatic conditions. That’s not enough; amidst these … Read More
Cadence Grows VIP Business – What’s New?
VIPs (Verification IPs) are really important in this complex world of SoCs which involve various IPs, interfaces and continuously evolving protocols and standards, thus making the task of verifying an overall system extremely challenging. And the verification must be done in minimum possible run-time and memory consumption.… Read More
Power and Reliability Sign-off – A must, but how?
At the onset of SoCs with multiple functionalities being packed together at the helm of technologies to improve upon performance and area; power, which was earlier neglected, has become critical and needs special attention in designing SoCs. And there comes reliability considerations as well due to multiple electrical and … Read More
Signal integrity: more than just SerDes analysis
When Cadence acquired Sigrity in 2012, two motives were involved: get more competitive in state of the art signal integrity analysis, and grab a foothold into the other vendor’s PCB flows in an area that is developing as a real sore spot for digital designers.
Just as the days where PCB tape-out meant actually using tape are over, … Read More
Power, Signal, Thermal and EMI signoff
Increasingly the challenge with SoCs, especially for mobile, is not getting the performance high enough but doing so in a power-efficient manner. Handheld devices running multiple apps need high-speed processors that consume extremely low levels of power both in operating and standby modes. In the server farm, the limit is … Read More
