Naked and Afraid – THE SEARCH FOR CAPITAL, Mon. May 5

Thursday, May 1st, 2014

Whether you are an entrepreneur or even thought about being one, you know that there are two things to worry about – time and money.

Everyone is welcome at the upcoming installment of the popular EDAC – Jim Hogan Emerging Companies Series, where Jim and other panelists (Amit Gupta, President and CEO, Solido Design Automation, Inc. and Vishal Kapoor, Principal, Three Legged Stool, LLC.) will discuss the sources of money – from crowdfunding to institutional investment to intrapreneural capital. The panel will debate the opportunities and risks associated with those sources and which one might be right for you.

Every entrepreneur believes that they know their product, but often only from a technical capability perspective. How you position, communicate and sell your product may be more important than it’s underlying capability. Without having a keen understanding of what you are building, how capital efficient it is and who needs it, the chances of getting that capital are significantly diminished.

Video Update: New Ascent XV Release for X-optimization, ChipEx show in Israel, DAC Preview

Thursday, April 17th, 2014

I stopped in at EELive! show in San Jose on April 2, 2014 and spoke with Sanjay Gangal, President of Internet Business Systems and EDACafe.com about the latest release of the Ascent XV X-verification system and its latest design reset optimization features. I also gave a preview of the activities at the ChipEx conference in Israel on April 30, 2014 and the Design Automation Conference in San Francisco on the dates of June 2-4, 2014.  Click on the picture to play the interview.

Design Verification is Shifting Left: Earlier, Focused and Faster

Thursday, April 10th, 2014

Recently, we have seen announcements by the Big Three EDA Companies about new initiatives in the area of SoC verification.  Synopsys for example, has started talking about Verification Compiler and how it is introducing static and formal checks for the first time, and relies on the Verdi debugging environment (acquired from SpringSoft) to tie it all together.  Real Intent has been delivering solutions focused static and formal for several years now (and also relies on Verdi for Debug).  The industry really started taking notice of this static verification trend in 2013 at DVCon and we have seen it grow through DAC 2013 in Austin.   We are now talking about designs crossing the billion-gate threshold and what can be done to not only control this explosion of complexity, but also to achieve sign-off for RTL code.

RTL and gate-level simulation theoretically can be used to fully test a billion-gate SoC, but the cost of complete RTL testing is beyond what design teams can afford. To reduce the testing cost and the risk of missing critical tests, abstract modeling and pre-simulation static analysis of RTL have now become imperative in SoC design flows. Integration of heterogeneous IP and design units require confirmation of protocols, power budgets, testability and the correct operation of multiple interfaces and clock domain crossings (CDC).

X-Verification: A Critical Analysis for a Low-Power World (Video)

Thursday, March 27th, 2014

The problem logic designers have with X’s is that RTL simulation is optimistic in behavior and this can hide real bugs in your design when you go to tapeout.  Some engineers point out that we have always had to deal with X’s and nothing has really changed.

In fact, today’s SoC employ different power management schemes that wake-up or suspend IP.  As any designer knows, when powering up logic, any X’s must be cleared on reset or within a specific short number of cycles afterword.   The situation is now much more uncertain for designers whether all possible power scenarios are considered and all X’s will be cleared correctly.

Sorting all of this out with your simulator is too much and will be too late in the design process.  So, the temptation is to supply a reset to all the flops in your design, but this will be costly in terms of precious routing density and power usage. Ideally, you would have a static tool that could analyze the rest scheme of your design and then suggest a minimum sub-set of flops that need reset lines.  This week, on March 25, Real Intent unveiled major enhancements in its  Ascent XV product for early detection and management of unknowns (X’s) in digital designs, which address this issue.

RTL SOC Verification Goes Better with Synopsys VCS and Verdi

Thursday, March 20th, 2014

Real Intent will exhibit its Ascent™ and Meridian™ products for advanced SoC sign-off at the SNUG® Designer Community Expo (DCE) – part of the Synopsys® Users Group (SNUG) Silicon Valley event March 24-26 – and also will make a presentation at the first Verdi Interoperable Apps (VIA) Developers Forum there. At the DCE, Real Intent will showcase its Meridian CDC and Ascent XV working with Synopsys’ industry-leading VCS® verification solution as a part of the IC Verification community.  Real Intent’s Ascent products find elusive bugs and eliminate sources of uncertainty that are difficult to uncover using traditional Verilog or VHDL simulation, leading to both improved QoR and productivity of design teams. Meridian products accelerate sign-off verification of clock domain crossings and SDC in 500+M gate SoC designs.

At the VIA Developers Forum, myself and Mathew Yee, Sr. Application Engineer will present and highlight the features and benefits of Real Intent’s product integration with the comprehensive Verdi debug environment and its application to particular debug challenges such as clock domain crossing (CDC) verification.

Engineers Have Spoken: Design And Verification Survey Results

Thursday, March 13th, 2014

This blog was originally published in SemiEngineering.com and I wanted to make sure EDACafe readers saw it as well.  I have also added some more content versus the original.  Enjoy!

Previously I have blogged about the verification surveys that Real Intent runs at tradeshows throughout the year.  We find it useful to track trends in tool needs and reveal what are the pain points designers are feeling.  I last reported to you, a year ago, in the blog article Clocks and Bugs, where I focused on clock-domain crossing (CDC) errors causing re-spins.

This year, I would like to add some additional highlights and trends that I see from new survey data.

DVCon Panel Drill Down: “Where Does Design End and Verification Begin?” – Part 3

Thursday, February 27th, 2014

At last year’s Design and Verification Conference (DVCon) in San Jose, Real Intent sponsored a panel on “Where Does Design End and Verification Begin?”  In this Part 3 we are continuing with the questions from the moderator and answers by the panelists.

The panel was moderated by Brian Hunter, Cavium, Inc. and panelists:

Pranav Ashar – Real Intent, Inc.
John Goodenough – ARM, Inc.
Harry Foster – Mentor Graphics Corp.
Oren Katzir – Intel Corp.
Gary Smith – Gary Smith EDA

Below are links into the video recording where the question is asked and the immediate replies and comments by the panelists.  Starting with Questions 15 the panelists shared several interesting insights about gaps with verification test-sets, and higher level modeling and had a lot of back and forth with the other members.
