The SPB16.3 SigXP UI has been enhanced to focus on giving users better access to information already available in SigXp, reducing the number of steps needed to accomplish simple tasks, provide functionality that enable easy data manipulation and provide better setup and default for an improved out of the box user experience.

In addition to those enhancements, a new layer stack approach has been added to SigXp, similar…

Good news! A long-standing source of irritation for Encounter users has been addressed in our 8.1.USR1 release.  You might not have noticed it if you've grown accustomed to backslash-escaping square brackets in object names.

For example:
selectNet DTMF_INST/RESULTS_CONV_INST/nbus_544[0]

In 7.1, if you tried to select a net with this syntax you'd get the following as the TCL interpreter treated the contents within the…

Say you have a design with 4 input frequencies: 3164M (vco), 1449M (tone0), 1456M (tone1), 1442M (tone2). Currently when you do a qpss analysis, you are inserting a total of 4 separate ports in your schematic and running a simulation.   There is a divide...

If you spend a lot of time reading and thinking about solid-state drives (SSDs), you may have gotten the impression that NAND Flash storage is at odds with hard-disk storage--that it's a winner-take-all situation. In his keynote at last week's pre-CES Storage Visions 2010 conference in Las Vegas, storage analyst Tom Coughlin dispelled that notion with some cogent slides and some…

Talk about unsung -- tech writers just don't get the credit they deserve.  They sit between R&D, customers, and support trying to capture the capabilities and intent of the software and present it accurately and succintly.  They record the "tribal knowledge" of the team so that new and existing users can function at their best, but then they hear that no one has read the f****** manual.

Well one of our…

Hi, I'm Thibault Alix and I have been working with the VLM team for two years. I'm going to present what's new in Virtuoso IC6.1.4.

Cadence® Virtuoso® Layout Migrate is the physical layout migration tool within the Cadence Virtuoso custom design environment. It supports fast process and design rule migration of hard IP, custom digital designs, mixed-signal blocks, memories, and standard cell libraries…

The Open Verification Component (OVC) defined by the official OVM User Guide in the OVM downloads enables the highest levels of reuse.  While the OVM class libraries have the supporting classes for the OVC built-in, writing OVCs properly sits on the shoulders of the verification engineer.  With Amiq's DVT, the verification engineer has the means to check their OVC for OVM compliance.

To help you learn more about DVT…

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…
