The Tale of Three Metrics
Meeting PPA (Performance, Power and Area) target is key to a successful design tapeout. These mainstream QoR (Quality of Results) metrics are rather empirical yet inter-correlated and have been expanded to be linked with other metrics such as yield, cost and reliability. While the recent CPU performance… Read More
Until recently, ICs at bleeding edge nodes like 7nm technology from foundries like TSMC were mostly targeted for high-performance-computing (HPC) and mobile applications or possibly high radix switches that needed the increased performance of advanced nodes. The momentum of Moore’s law and Moore-than-Moore saw foundries… Read More
While at the 54[SUP]th[/SUP] Design Automation Conference (DAC) I had the opportunity to talk with Ruben Molina, Product Management Director for Cadence’s Tempus static timing analysis (STA) tool. This was a good review of how the state-of-the-art for STA has evolved over the last couple decades. While the basic problem hasn’t… Read More
It requires lateral thinking in bringing new innovation into conventional solutions to age-old hard problems. While the core logic design has evolved adding multiple functionalities onto a chip, now called SoC, the structural composition of DFT (Design for Testability) has remained more or less same based on XOR-based compression… Read More
Yesterday was the first day of CDNLive. There were three keynotes. The first was by Lip-Bu Tan, Cadence’s CEO (and the Chairman of Walden International that he will be the first to remind you). The most interesting tidbit was that Cadence now has over 1000 people working on IP and that it represents 11% of their revenue. Then… Read More
Last month Cadenceannounced its fastest parasitic extraction tool (minimum 5 times better performance compared to other available tools) which can handle growing design sizes with interconnect explosion, number of parasitics and complexities at advanced process nodes including FinFETs, without impacting accuracy of … Read More
The semiconductor design sizes, these days, can easily be of the order of several hundred millions of cells, adding into the complexity of verification. Amid ever growing design sizes, it’s a must that the timing verification is done accurately. Normally Static Timing Analysis (STA) is done to check whether all clocks and signals… Read More
Yesterday Cadence had an all-day Signoff Summit where they talked about the tools that they have for signoff in advanced nodes. Well, of course, those tools work just fine in non-advanced nodes too, but at 20nm and 16nm there are FinFETs, double patterning, timing impacts from dummy metal fill, a gazillion corners to be analyzed… Read More
Cadence’s Signoff Summit will be held next week, November 21 at Cadence in San Jose.
This is the first of a series of all-day Signoff Summits from Cadence that focus on the multiple facets of design signoff. This first summit will include keynote addresses plus sessions covering the multiple solution components that comprise… Read More
I had time for lunch on Monday. That is to say, there was a Cadence panel session about Has Timing Signoff Innovation has become and Oxymoron? What Happened and How Do We Fix It?
The moderator was Brian Fuller, lately of EE Times but now Editor-in-Chief at Cadence (I’m not sure quite what it means either). On the panel were Dipesh… Read More
