Synopsys Acquires Ciranova

Synopsys Acquires Ciranova
by Daniel Payne on 07-30-2012 at 6:00 pm

Consolidation continues in the EDA industry with Synopsys announcing today that they acquired Ciranova, a provider of software to automate custom IC layout. Remember that Synopsys invested in Ciranova back in March 2008 and September 2010 (along with Intel Capital, Mentor Graphics and Alloy Ventures), so this deal has some … Read More


Parasitic-Aware Design Flow with Virtuoso

Parasitic-Aware Design Flow with Virtuoso
by Daniel Payne on 07-27-2012 at 12:01 pm

I learn a lot these days through webinars and videos because IC design tools like schematic capture and custom layout are visually oriented. Today I watched a video presentation from Steve Lewis and Stacy Whiteman of Cadence that showed how Virtuoso 6.1.5 is used in a custom IC design flow:… Read More


Libraries Make a Power Difference in SoC Design

Libraries Make a Power Difference in SoC Design

At Intel we used to hand-craft every single transistor size to eek out the ultimate in IC performance for DRAM and graphic chips. Today, there are many libraries that you can choose from for an SoC design in order to reach your power, speed and area trade-offs. I’m going to attend a Synopsys webinar on August 2nd to learn more Read More


How Do You Extract 3D IC Structures?

How Do You Extract 3D IC Structures?
by Daniel Payne on 07-18-2012 at 2:01 pm

The press has been buzzing about 3D everything for the past few years, so when it comes to IC design it’s a fair question to ask how would you actually extract 3D IC structures for use by analysis tools like a circuit simulator. I read a white paper by Christen Decoin and Vassilis Kourkoulos of Mentor Graphics this week and became… Read More


An Approach to 20nm IC Design

An Approach to 20nm IC Design
by Daniel Payne on 07-17-2012 at 10:10 am

Last month at DAC I learned how IBM, Cadence, ARM, GLOBALFOUNDRIES and Samsung approach the challenges of SoC design, EDA design and fabrication at the 20nm node. Today I followed up by reading a white paper on 20nm IC design challenges authored by Cadence, a welcome relief to the previous marketing mantra of EDA 360.

Here’s… Read More


Using Synopsys Analysis Tools for AMS Design

Using Synopsys Analysis Tools for AMS Design
by Daniel Payne on 07-11-2012 at 12:05 pm

I attended the Synopsys webinar today for a tool called Custom Explorer Ultra (CXU). Product details on the Synopsys web site are here. The CXU tool would be used by AMS designers that want to setup, control and view results from simulators like HSPICE, CustomSim or VCS on transistor-level and AMS designs.… Read More


SPICE Timing Correlation for IC Place and Route

SPICE Timing Correlation for IC Place and Route
by Daniel Payne on 07-10-2012 at 10:35 am

SPICE circuit simulation is used for transistor-level analysis while Place and Route tools are typically used to connect cells and blocks of an SoC, so why would there be a connection between these two EDA tools?

I read a press release today from ATopTech and Berkeley Design Automation that talked about how SPICE and P&R are … Read More


IC Design at Novocell Semiconductor

IC Design at Novocell Semiconductor
by Daniel Payne on 07-05-2012 at 12:09 pm

In my circuit design past I did DRAM work at Intel, so I was interested in learning more about Novocell Semiconductor and their design of One Time Programmable (OTP) IP. Walter Novosell is the President/CTO of Novocell and talked with me by phone on Thursday.… Read More


Managing Differences with Schematic-Based IC Design

Managing Differences with Schematic-Based IC Design
by Daniel Payne on 07-02-2012 at 2:41 pm

At DAC in June I didn’t get a chance to visit ClioSoft for a product update so instead I read their white paper this week, “The Power of Visual Diff for Schematics & Layouts“. My background is transistor-level IC design so anything with schematics is familiar and interesting.

The Challenge
Hand-crafted … Read More


Robustness, Reliability and Yield at DAC

Robustness, Reliability and Yield at DAC
by Daniel Payne on 06-26-2012 at 8:15 pm

On Wednesday at DAC I met with Bob Slee, distributor and Michael Siu, AE for MunEDA to get an update on what’s new. MunEDA has EDA software for:

  • Schematic porting
  • Nominal circuit analysis
  • Nominal circuit optimization
  • Statistical circuit analysis
  • Statistical circuit optimization
  • IP porting
  • Circuit model generation
