Placement replication was introduced in Allegro PCB Editor SPB16.2. At that time, the application was limited to replication of component placement. The SPB16.3 release introduces the support of etch circuits (shapes, clines, vias) as well as ease of use improvements associated with basic move, mirror and rotate functions. Once replicated circuits are placed, physical changes such as moving components or modifying etch…

As an ex-design engineer now working in EDA, I am often privileged to see advanced design methodologies from many of my customers. I would like to reflect on the recent trends that I am seeing around signoff analysis for digital ASIC designs.

For the majority of ASIC designs, signoff analysis includes executing parasitic extraction that feeds static timing analysis, signal integrity analysis and power rail IR drop…

"As a New Media evangelist...I've been able to categorize those reactions into three different personality types: The 'Get-Its,' the 'Traditionals,' and my favorite group, those 'Running with Scissors'" -Ron Ploof

When I was out in California recently, I had a chance to sit down with author Ron Ploof.  Ron has worked at Cadence…

In MMSIM 7.2, two new parameters have been added to the Spectre nport primitive: datatrunc and causality. In MMSIM 7.1, passivity checking was added. The nport now has causality correction, passivity checking and enforcement, and the ability to remove...

I love top 10 lists.  Not so much for the drama of the count-down, but for arguments that inevitably fall out of any prioritization.  So here is my verification top 10 in '10, let the rants begin!

10. VHDL 1076-2009 Support.  Huh? How did this get here? Given the breadth of IES (Incisive Enterprise Simulator) use across the industry we have requirements from every imaginable source so calling out VHDL is a great example…

What's good about it is that we don't need to reflect occasionally.

We can reflect on our lives often. During this Christmas and Hanukkah time, many Judeo–Christian people celebrate the spirituality of the season by reflecting on family, friends, and colleagues and the blessings of our lives throughout the year.

This past year has brought tougher times for our industry. Some of my friends have been struggling…

Historically it’s been very common for e users to have to mix other programming languages with their e verification environment.  Some examples include adding C or C++ reference models, contributing e Universal Verification Components (UVCs) to non-e testbenches, or even interfacing to Matlab models.  To stay in the vanguard of this ongoing trend, the 9.2 Update release posted last week is specifically aimed at formalizing…

Greetings,

In the previous appends, we looked at using Shooting Newton Periodic Steady-State analysis to analyze analog circuits. In this append, we will look at using Harmonic Balance Periodic Steady-State, HBPSS, to analyze analog circuits. HBPSS is...

I just got back from a trip to California where I met with a couple of customers and presented database access with dbGet in the Encounter Digital Implementation System (EDI for short).  I took notes on the questions that came up- in particular those common between both sets of users.  One item in particular that was helpful was understanding how to select objects by pointer with dbGet.  In this post, I'll explain the basics…

Would you like to be doing more with your Enterprise Manager environment but just don’t have the time to figure out how to do it? Maybe things like automated email notifications, project tracking over time, and more automated debug? If you’re interested in any of these, then here is a holiday gift for you…

The SPB16.3 release is now available (actually, it was available last week from the Cadence software downloads site at - http://downloads.cadence.com/).

Where has the year gone! It seems like only yesterday I was blogging about all the cool new SPB16.2 features - and now the SPB16.3 release will add additional improvements and efficiencies to your design process.

Over the next several weeks, I'll be writing about key new…

A professional gambler confidently place bets because she know the odds, but she would be crazy to play at a table that didn’t use a full deck because the odds change in an unknown way.  If you use a simulator that doesn’t enable low-power verification in every test run, you are just as crazy.

Why? Let’s take a look at what gives the verification engineer confidence – finding bugs.  If we have a power…

By now, you've surely heard the news.  And if you haven't yet, you have now.  Virtuoso IC 6.1.4 is now available!  Huzzah, huzzah! 

I was (and still am) planning to do my next series of "Things You Didn't Know" about ADE XL, but for now I feel I'd be remiss if I didn't pause and devote a few posts to the new features in IC 6.1.4.  Those are very likely "things you don't know" since they are brand…

Specmaniacs rejoice: today is the 1st anniversary of the launch of this blog!!!  To commemorate the occasion, allow us to highlight the top 5 posts (out of 72 total!) from the past year, AND give a shout out to the Specmaniac websphere with a roll-up of Specman and e language oriented online resources.  Without further adieu, in ascending order of web hits and comments received …

#5 – Tech Tip - Double Wall…

What a terrific event last Wednesday! The SPB16.3 Virtual Conference was attended by more than 600 customers.

If you could not attend the live session, the web based event is still open for the next 4 months (until April 2, 2010) - so please open your browser, step into the virtual conference from the convenience of your desktop and explore all of the rich content you may have missed or would like to see again.

I attended…

As we are all creatures of habit, sometimes it's hard to adapt to new work flows no matter how beneficial the change may be. Clearly this is the case in the transition of the Specman GUI from Specview to SimVision; so allow me to share with you some quick tips to ease the transition process and/or make you more productive with SimVision. …
