Virtuoso Video Diary: SKILL IDE Performance Analysis Tools

By Deepti Kamal | 21 Sep 2016

As a SKILL code developer, do you spend a major chunk of your time in fine-tuning your SKILL code? I am sure nobody writes perfect code in the first attempt. Producing efficient and bug-free code involves several iterations of proactively monitoring the code, eliminating bottlenecks, and analyzing as well as improving its performance. And there are tools that can help you improve your code’s performance without...

Analog Design Resonance: Playing with Filters

By TeamADE Cadence | 20 Sep 2016

We'd like to welcome guest writer Yanyan Qiao from our Cadence Japan AE team. Many thanks for her contribution! Today analog design has become very challenging. Analog circuit designers need tools which can provide deep insight into circuit behavior. The MMSIM simulator family provides device check functions, as well as static circuit topology checks and dynamic behavior check functions for typical design problem...

Virtuoso Video Diary: Introducing WSP Manager

By Pam Gazlay | 30 Aug 2016

Are you an advanced node layout or CAD engineer trying to find a methodology for routing designs in the Virtuoso platform? Interested to learn how to specify tracks for correct-by-construction designs using width spacing patterns (WSPs)? If you are not using the WSP Manager in the Virtuoso environment to create and modify your WSPs, now is the time to try it. Using Width Spacing Patterns for Advanced Node Designs ...

High-Sigma Showdown: Which Method is Better?

By TeamADE Cadence | 18 Aug 2016

The adoption and usage of advanced node technology (16nm and below) has been extraordinary over the last few years. However, along with the benefits in power and area, the new nodes also contain new challenges when it comes to properly determining the variation caused by the smaller geometries. Much has been written about the proper ways to physically implement a FinFET design, but less has been written on the need for...

Virtuoso Variation Option: Reliable High-Yield Design with Scaled-Sigma Sampling

By TeamADE Cadence | 1 Aug 2016

What’s Scaled-Sigma Sampling? Scaled-sigma sampling (SSS) is an efficient algorithm to solve the high-yield estimation problem, which happens when your circuit needs to have a really low failure rate, like one in a million or one in a billion. This can be because you are designing a highly repetitive circuit like a memory cell or flip-flop, or you are an automotive or medical designer who just wants to be very...

Virtuoso Video Diary: Getting Started with the New ADE Product Suite

By Namrata Malhotra | 28 Jul 2016

Hey, did you hear the buzz around the new Virtuoso ADE product suite, which was introduced in IC6.1.7? The products in this suite—Virtuoso ADE Explorer, Virtuoso ADE Assembler, and Virtuoso ADE Verifier—have made a good start, just as we expected! The new single-test simulation environment, Virtuoso ADE Explorer , provides some really exciting features. Our favorite ones are real-time tuning with Spectre...

Adding Weighted Noise Via Calculator Custom Function

By TeamADE Cadence | 28 Jul 2016

Applying a weighting factor to a Noise Summary run requires lots of steps and the results cannot be evaluated without using the form. Wouldn't it be much easier if you could have a calculator function to do this? You can create a custom function in the calculator that uses the script attached, weightedTotalNoise.il, simplifying this flow. Traditional Flow In order to apply a weighting factor to a Noise Summary...

Waveform Thumbnails

By TeamADE Cadence | 17 Jun 2016

Wouldn't it be great if you could see your plots directly on the schematic? Well in ADE Explorer, now you can! Run a simulation in Explorer and open the design in tab and choose Waveforms from the show/hide balloon drop down or use the bind key CTRL+B Hover over the nets/terminals in the design and balloons showing the simulation plot will appear. To pin the balloons use the bindkey SHIFT+B or...

Virtuoso Video Diary: Redesigned Virtuoso Forms

By Komal Johar | 13 Jun 2016

Enhanced User Experience with Redesigned Virtuoso Forms Research and customer feedback has revealed that you feel some Virtuoso forms are quite complex, with too many options displayed on the forms and use models that are unclear. Based on your feedback, we have begun redesigning the most frequently used forms across Virtuoso applications. As you start to use the redesigned forms in Virtuoso, you will see that they...

Analog Design Resonance: When a Plan Comes Together

By TeamADE Cadence | 7 Jun 2016

Yes, indeed, we all love it when a plan comes together. A plan for running all the simulations you need, using different combinations of tests, corners, variables, and run modes. A plan that you can execute with a single button before you go home in the evening. A plan that will stop if, for some reason, your design isn't performing to spec so that you aren't wasting resources running simulations on a bad design...

The Leader of the Orchestra: Getting Started with Virtuoso ADE Verifier

By TeamADE Cadence | 25 Apr 2016

The members of an orchestra are often great virtuosi on their own instruments, but the conductor - the maestro – is equally important. The maestro has his score on the conductor’s stand to know exactly what is supposed to be played. He explores the individual intonation and assembles the orchestra into a unique sound. Most importantly, he has to verify that every single tone fits the master plan – the...
