Want to know how NVIDIA signs off on power integrity and reliability on mega-chips? Read on.

PPA over-design has repercussions in increased product cost and potential missed schedules with no guarantee of product success. Advanced SoCs pack more functionality and performance resulting in higher power density, but traditional… Read More


The Transistor is the Foundation of TCAD to Signoff

The Transistor is the Foundation of TCAD to Signoff
by Paul McLellan on 06-04-2015 at 7:00 am

Image RemovedAt the most basic level, semiconductor design is all about transistors. Any report on a large microprocessor or mobile application processor is in awe about how many transistors it contains. Moore’s Law is all about the most economic way to manufacture transistors. Each process generation for the last decade and… Read More


A Complete Scalable Solution for IP Signoff

A Complete Scalable Solution for IP Signoff
by Pawan Fangaria on 10-20-2014 at 7:00 am

In an SoC world driven by IP, where an SoC can have hundreds of IP (sourced not only from 3[SUP]rd[/SUP] party but also from internal business units which can have a lot of legacy) integrated together, it has become essential to have a comprehensive and standard method to verify and signoff the IP. Additionally, these checks must … Read More


A Complete Timing Constraints Solution – Creation to Signoff

A Complete Timing Constraints Solution – Creation to Signoff
by Pawan Fangaria on 09-28-2014 at 10:00 pm

With the unprecedented increase in semiconductor design size and complexity design teams are required to accommodate multiple design constraints such as multiple power domains for low power design, multiple modes of operation, many clocks running, and third party IPs with different SDCs. As a result timing closure has become… Read More


Automatic RTL Restructuring: A Need Rather Than Convenience

Automatic RTL Restructuring: A Need Rather Than Convenience
by Pawan Fangaria on 08-22-2014 at 5:00 pm

In the semiconductor design industry, most of the designs are created and optimized at the RTL level, mainly through home grown scripts or manual methods. As there can be several iterations in optimizing the hierarchy for physical implementation, it’s too late to do the hierarchical optimizations after reaching the floor plan… Read More


Signoff Accurate Timing Analysis at Improved Run-time & Capacity

Signoff Accurate Timing Analysis at Improved Run-time & Capacity
by Pawan Fangaria on 04-18-2014 at 4:30 pm

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


Signoff Summit and Voltus

Signoff Summit and Voltus
by Paul McLellan on 11-22-2013 at 10:21 am

Image RemovedYesterday 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… Read More


DAC: Tempus Lunch

DAC: Tempus Lunch
by Paul McLellan on 06-06-2013 at 4:03 pm

Image RemovedI 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 … Read More


Atrenta: Mentor/Spyglass Power Signoff…and a Book

Atrenta: Mentor/Spyglass Power Signoff…and a Book
by Paul McLellan on 05-30-2013 at 7:00 am

Image RemovedToday Atrenta and Mentor announced that they were collaborating to enable accurate, signoff quality power estimation at the RTL for entire SoCs. The idea is to facilitate RTL power estimation for designs of over 50M gates running actual software loads over hundreds of millions of cycles, resulting in simulation… Read More


RTL Signoff Theater

RTL Signoff Theater
by Paul McLellan on 05-29-2013 at 11:00 am

Image RemovedWe have talked for years about RTL signoff, the idea that a design could be finalized at the RTL level and then most of the signoff would take place there. Then the design would be passed to a physical implementation team who would not expect to run into any problems (such as routing congestion, missing the power budget… Read More
