What Does Cadence’s Aquisition of Denali Mean for Denali Customers?

May 14th, 2010

The short answer to the question posed in the title is: Nobody knows.  It all depends on Cadence.  It could be good, or it could be bad.  So what’s my point?

FMF has always, since 1995, provided models as standards compliant source code.  One of the advantages to our users is that no matter what happens to FMF, you can keep using our models forever.  There are no run time licenses.  There is no compiled code to be recompiled with the next OS upgrade.  There is nothing tying a model to a particular release of a simulator.  Nothing provides the long term security of having the source code.

Now you won’t (and we haven’t) get rich with this business model.  FMF was started by engineers trying to solve the model scarcity problem.  We all had day jobs that involved designing electronic systems and we were trying to make those jobs easier.  We were also working in an industry that had 20-year product life cycles.  Stability was a requirement.  I realize that is not true in every industry.

There are other advantages to open source models.  I talk about them else elsewhere on these pages.  For now, we are reminded that long term usability is one important advantage.

End of the System Verification Forum

January 31st, 2010

The System Verification Forum previously found elsewhere on this website has been shut down.  Last year the level of spam became intolerable.  The site was changed to make posting more difficult.  This resulted in a 90% reduction in spam but a 100% reduction in relevant posts.  Therefor, I have decided to discontinue the forum.  In its place, please feel free to post comments to this blog.

Consumer Electronics Show

November 12th, 2009

I just signed up for the 2010 Consumer Electronics Show in Las Vegas, January 7-10 and thought I should remind you about it too.

Since this blog is aimed at engineers, you may be wondering why I would mention a consumer show.  So, here are my reasons for going -you can judge if they apply to you.

1.  It is a lot of fun.  There are miles of exhibits, lots of cool demonstrations, and some sessions like “Last Gadget Standing” to appeal to the geek in each of us.

In case that doesn’t justify getting out of the office:

2.  It is informative.  You can see what new and exciting products your competitors are working on and how close they are to production.  It may even give you some ideas for your own work.

Still not enough?

3.  CES Partner Sessions.  There are 24 (count them) concurrent conferences and summits ranging from the “Cable Conference” to “Technology and Emerging Countries”.  One of them may be important to your industry.  I will be at the Digital Health Summit because I am working on a project related to that.

4.  Las Vegas is a fun place with “interesting” places to spend your evenings.

Registration is just $100 till January 2.

See you there.

OpenSource World 2009

August 14th, 2009

OK, this is not verification related but it should be of interest to engineers.  On Wednesday and Thursday I attended OpenSource World (formerly Linux World) at Moscone West in San Francisco.  I missed the show last year but it was significantly smaller this year than in 2007.  The exhibit area in particular was a fraction of its previous size.  However, there were still over 100 presentations in 9 tracks.  The ones I attended were all well worth the time.

There was one keynote address that surprised and impressed me.  It was given by Deborah Bowen, the California Secretary of State.dbowen_20090812

Secretary Bowen spoke about a number of issues but mostly about security issues surrounding electronic voting machines.  This was a conference of software developers and and network administrators.  I would expect a politician foolish enough to stand in front of this group and talk about anything technical, much less an issue about which they are likely to harbor strong opinions, would come away bruised and looking like a buffoon.  This is why I was so surprised that Secretary Bowen proved so technically competent and able to field the most detailed questions.  She explained the vulnerabilities that had been uncovered in various voting machines leading to their decertification and what would be required for a new machine to be certified.  She also told a great story of how her office decided to try using cloud computing to handle the peak election night loads on the Secretary of State’s website.  The result was that instead of spending $800,000 on computer upgrades, they paid a $7 bill to Amazon for EC2 usage.

At times like these, it may be difficult to believe but, we actually do have someone intelligent in Sacramento.

Flash Summit Off to Great Start

August 11th, 2009

The Flash Memory Summit at the Santa Clara Convention Center got off to a great start today.  The three day agenda is packed with interesting talks on all aspects of flash memory.  According to Tom Coughlin, registration so far has topped 1200, a new high.  The fact that half the registrations came in just the last two weeks, Tom takes as a sign people are  becoming more optimistic about the economy.

This is the packed house that received Ed Doller’s keynote talk at 11:30.  Ed again spoke enthusiastically (that is his job) about Numonyx‘ soon-to-be-released Phase Change Memory (PCM).  He was able to give a few more details this time and told us specifications are available under non-disclosure.

The program for the rest of the conference sounds wonderful.  Unfortunately, I have other business at the OpenSource Wold (formerly Linux World) Conference in San Francisco tomorrow and Thursday.
