I'm switching gears this week from my regular SPB technical product posts to focus on an annual Cadence event - Cadence Innovation Day.

Today Cadence will honor the 2008 recipients of the Excellence in Innovation Awards. This year, 35 winners will be celebrated amongst their peers from all geographies and organizations - 13 of this year's recipients are from locations outside San Jose.

Adam Sherer is one of this…

On Tuesday this week we are celebrating "Innovation Day" here at Cadence, honoring inventive engineers across the company. 

I must admit that most of the time I get so bogged down with the latest customer questions or figuring out how to help people learn about the latest features that I forget about all those folks in R&D whose raison d'etre is to come up with new and better ways of doing things.  And…

Your kids may be going house to house for treats, but you can get a big OVM sugar rush from Cadence's OVM World contributions.  Each delectible nugget is wrapped in documentation that helps you savor all the goodness. So reach into the bowl and indulge in these methodology sweets!

Callback Mechanism

From day 1 the OVM has employed a factory mechanism for both simple reuse and multi-language consistancy.  While factories…

Is it their raw power?  Is it the cheerleaders?  Why are verification engineers like football players?  It's because they know how to squeeze the maximum performance out of their resources to win the verification game. Charlie Dawson, Senior Engineering Manager at Cadence, has been leading teams that build performance into our products for years and has taken some time to put the whole game in perspective.  Read more…

Here's a simple but useful tip that shows how to write to the log file using the Encounter command "Puts"...

In TCL, the "puts" command is use to write information to the console -or- to a file.  For example:

encounter 63> puts "hi"
hi

-or-

encounter 64> set outfile [open test "w"]
file18
encounter 65> puts $outfile "hi"
encounter 66> close $outfile
encounter…

Color assignment in Allegro PCB Editor has been accomplished with either a class/subclass color assignment or a color assignment done with the highlight command. With designs becoming more complex, it's desirable to be able to assign colors, including custom colors to independent objects.

Database elements may be displayed using either the class/subclass color or a single color assigned to an element, also known…

Specmaniacs rejoice: long time Verification Alliance partner AMIQ has just added OVM e compliance checking to their "DVT" integrated development environment (IDE). Here is a 4 minute video demo with the highlights of this new capability:

To get the full scope of the DVT tool and AMIQ as a company, recall the 5 minute general demo of the tool in an earlier post,…

Cadence and Mentor have dedicated teams to the development and support of the OVM and you, our user community, have literally tens of thousands of developers dedicated to developing reusable VIP with it.  But where do “you” and the OVM meet?

Sometimes the “you” is obvious – the OVM World Forum.  With 1100+ unique threads and 4500+ posts, the OVM Forum is by far the most active testbench and…

Sorry I've been missing from this space for so long.  I've been busily working on a number of projects to try to help get the word out about all the features I have been (and will be) blogging about.  I've also been becoming an expert on making video demos, some of which I'll try to feature here too.  Ask your Cadence rep about the new VSE L/XL and ADE XL/GXL interactive Quick Start Guides.  (If they don't…

These tips are applicable to the Encounter Digital Implementation System.

Back in the good old days, I remember asking designers at the beginning of a silicon virtual prototyping evaluation "Where is your timing constraints file?"  Note the singular form of the word file- was it really that simple?  Didn't seem so easy at the time.  While the complexity of timing constraints in terms of their content has increased…

Believe it or not, sometimes a marketing guy just needs to say less. It's true. It does happen. Sometimes we do just get right to the point. Yeah, we do blather on sometimes but ... oops, there I go again. Just listen to John. He has 10 great reasons to adopt the OVM.

If video fails to play please click here.

Question? You can post them here or send them directly to John at john.aynsley@doulos.c…

As clock and data frequencies increase and high-speed systems become ever more densely populated, the distribution of power becomes a major challenge for package power/ground design. To ensure that high-speed systems continue to deliver the required performance at these new signal frequencies, power distribution impedance has to be controlled over a wider range of frequencies. This can be accomplished through careful…

One of the great things about working here at Cadence is having the opportunity to test and preview new features and functionality before public release.  The newly released 9.2 version of Incisive Enterprise Simulator contains a new streamlined signal tracing function in SimVision.

I thought you might like to see a preview demonstrating the new capabilities for tracing signals directly within the source browser, as well as updates…

[For those of you that didn't / can't make it to a ClubT last week/this week, here is a meaty technical article from guest bloggers Matan Vax (R&D Architect), Yuri Tsoglin (R&D), and Dean D'Mello (CoreComp Architect)]

When subtypes let you add properties and behavior to a struct or a unit when one or more enumerated/boolean fields take on specific values. The fields that define when subtypes…

Last week Cadence announced a new product called Incisive Enterprise Verifier (IEV) that combines simulation and formal technologies in unique and interesting ways. I am very excited about IEV for two good reasons. The first is simply that it's the product I've been most involved with during my time at Cadence, so I have a personal stake in its success. The bigger reason is my vision that IEV will be the primary tool…

Last week we announced Incisive Enterprise Verifier (IEV). What is cool about IEV is that it integrates formal analysis and simulation engines in unique ways that provide users with more power. One of the great things about IEV is that it is easy to use and get value quickly. It is all about helping to reduce the overall verification time.

Take a look at the press release, and read Richard Goering's blog …
