How To Design a TSMC 20nm Chip with Cadence Tools

How To Design a TSMC 20nm Chip with Cadence Tools
by Paul McLellan on 05-07-2013 at 8:10 pm

Every process node these days has a new “gotcha” that designers need to be aware of. In some ways this has always been the case but the changes used to be gradual. But now each process node has something discontinuously different. At 20nm the big change is double patterning. At 14/16nm it is FinFET.

Multi-level abstraction accelerates verification turnaround

Multi-level abstraction accelerates verification turnaround
by Pawan Fangaria on 05-02-2013 at 8:30 pm

Often a question is raised about how SystemC improves verification time when the design has to go through RTL in any case. A simple answer is that with SystemC, designs can be described at a higher level of abstraction and then automatically synthesized to RTL. When the hands-on design and verification activity is at a higher level,… Read More


Cadence ♥ TSMC

Cadence ♥ TSMC
by Daniel Nenni on 04-19-2013 at 6:00 pm

TSMC has been investing in the fabless semiconductor ecosystem for 25+ years and that is why they are the #1 foundry and lead this industry (my opinion). I’m a big fan of joint webinars. Not only is it collaboration open to the masses, it is a close collaboration between the two sponsoring companies. Having worked on the TSMC… Read More


Variation-aware IC Design

Variation-aware IC Design
by Daniel Payne on 04-15-2013 at 4:18 pm

We’ve blogged before about Layout Dependent Effects (LDE) on SemiWiki and how it further complicates the IC design and layout process, especially at 28nm and lower nodes because the IC layout starts to change the MOS device performance. There’s an interesting webinarfrom Cadence on Variation-aware IC Design, … Read More


Two New TSMC-Cadence Webinars for Advanced Node Design

Two New TSMC-Cadence Webinars for Advanced Node Design
by Daniel Payne on 04-15-2013 at 3:43 pm

Foundries and EDA vendors are cooperating at increasing levels of technical intimacy as we head to the 20nm and lower nodes. Cadence has a strong position in the EDA tools used for IC design and layout of custom and AMS (Analog Mixed-Signal) designs. They have created a series of webinars to highlight the design challenges and new… Read More


Cadence Sues Berkeley Design Automation

Cadence Sues Berkeley Design Automation
by Paul McLellan on 04-10-2013 at 10:03 am

Cadence has brought a suit against Berkeley Design Automation for, as far as I can see, integrating their AFS circuit simulator with the Virtuoso Analog Design Environment (ADE) without using the (licensed) Oasis product. Since BDA is (actually was) a member of the Cadence Connections program, they have to abide by the contract… Read More


Manage your IC’s Stress for right performance

Manage your IC’s Stress for right performance
by Pawan Fangaria on 04-09-2013 at 9:30 pm

As we have moved towards lower process nodes to improve performance of ICs with higher density and functionality, many manufacturing effects have appeared which can render ICs useless, even though the layout design could be correct as per traditional design rules. What is more worrisome is the variability of these effects which… Read More


Signal integrity: more than just SerDes analysis

Signal integrity: more than just SerDes analysis
by Don Dingee on 03-29-2013 at 1:00 am

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


Mixed-Signal SoC verification has integrated solution

Mixed-Signal SoC verification has integrated solution
by Pawan Fangaria on 03-21-2013 at 8:10 pm

These days when we talk of SoC verification, what comes to our mind immediately is VirtualPlatform. Of course with the increasing size, complexity and different styles of designs, it is very much a need.

However, that is supported by actual verification engines and methodologies which are varying considerable with digital, … Read More

A tour of today’s Mixed-Signal solution
by Pawan Fangaria on 03-18-2013 at 10:00 pm


Mixed-Signal design is one of the very initial design methodologies, pioneered by Cadence with its lead in custom design; now taking centre space in the world of SoCs. Its growth is surmountable as it finds its place in most of the high growth electronics like smart phones, automotive applications, networks and communications,… Read More
