Once a chip is taped out, changes in design are not possible – Silicon is unforgiving, does not allow postproduction modifications. In contrast, software can be updated after release, but chips remain fixed. Static Timing Analysis (STA) signoff serves as a crucial safeguard against silicon failures.

The relentless advancement of mobile phone technology continues to push boundaries, demanding SoCs that deliver ever-increasing performance while preserving extensive battery life. To meet these demands, the industry is progressively embracing lower technology nodes with current designs being taped-out at 5nm or below.… Read More
Synchronous circuits dominate the electronic world because clocking eases the design of circuits compared to asynchronous circuits. At the same time, clocking also introduces its share of challenges to overcome. No wonder, a tremendous amount of time and effort have been spent over the years on developing and implementing … Read More
At the recent Design Automation Conference, Cadence presented their methodology for incorporating performance degradation measures due to device aging into a static timing analysis flow. [1] (The work was a collaborative project with Samsung Electronics.) This article reviews the highlights of their presentation.

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
At SemiWiki we’ve been blogging for several years now on the semiconductor design challenges of FinFET technology and how it requires new software approaches to help chip designers answer fundamental questions about timing, power, area and design closure. When you mention the phrase Static Timing Analysis (STA) probably… Read More
In Chaucer’s Canterbury Tales, the second of the tales told by the pilgrims is The Miller’s Tale. Since this is a family blog, I’ll leave you to research the tale yourself. But FinFETs hide another Miller’s Tale, due to Miller capacitance, sometimes called the Miller effect. This is significant since in FinFET designs Miller capacitance… Read More
When I hear the phrase Static Timing Analysis (STA) the first EDA tool that comes to mind is PrimeTimefrom Synopsys, and this type of tool is essential to reaching timing closure for digital designs by identifying paths that are limiting chip performance. Sunil Walia, PrimeTime ADV marketing lead spoke with me by phone on Thursday… Read More
