Do you access Cadence Support Portal (https://support.cadence.com) often?

If yes, you may be interested to know what has been happening to the site lately. There have been many enhancements and changes!

If you have not visited us recently, you may be...

Yes, it's true. After who knows how many years, EDPS is not going to be in Monterey, but in Milpitas. They still seem to be keeping the dolphin logo though. So, yes, dolphins in Milpitas.

EDPS is the Electronic Design Process Symposium. It is a relatively...

Historically, one of the great challenges that analog and mixed-designers face has been accounting for the effect of process variation on their design. Minimizing the effect of process variation is an important consideration because it directly impacts the cost of a design. From Pelgrom’s Law (1), it is understood that the device mismatch due to process variation decreases as the square root of increasing device area…

Cadence Online Support has this Rapid Adoption Kit (RAK) on Rigid-Flex in Allegro PCB Editor 17.2 that introduces a flow to define unique stackups by physical zone. The Cross Section Editor in 17.2 has been enhanced to support multiple stackup definitions including support for mask and coating layers. The primary driver for this enhancement is Rigid- Flex applications where it’s common to have different fabrics across…

This week we move to Britain. The industrial revolution started in the Midlands there, and I highly recommend visiting Blists Hills Museum (near Ironbridge which is the first...you'll never guess...iron bridge, from 1779). This is truly the cradle of...

The concept of Save and Restore is simple: instead of re-initializing your simulation every time you want to run a test, only initialize it once. Then you can save the simulation as a “snapshot” and re-run it from that point to avoid hours of initialization times. It used to be inconvenient. Using this feature in simulators could have massive productivity gains, but not all users made the most of it due to…

How's that for click bait? But it's actually true.I didn't know what the SDI of Samsung SDI actually stood for. So I tried to discover. It is harder than you think to find out, partially because the answer is a bit too cute, and so I guess they stopped...

In this series, we will focus on advanced concepts for custom IC design, in particular, variation-aware design (VAD). With emergence of high-speed simulators such as Spectre^® APS, designers can now run simulations faster than ever before, so they are able to more completely verify their designs before taping out. However, it requires more than verifying the proper functionality for different stimulus and performance…

Comparing waveform outputs of a simulation run with the outputs of a “golden“ or any other “previous“ run is one of the regular tasks that analog designers perform while tuning their designs to meet the requirements. At times, it requires performing multiple iterations of several tasks, such as running simulations and comparing results, making changes in the comparison criteria, checking whether the expectations are…

So the new Doctor Who will be a woman. Who(!) would have guessed?

As it happens, I saw the very first episode of Dr Who (in B&W). Because of a macabre coincidence, I can even tell you the date. It appeared the day following President Kennedy's assassination...

There are more ways to improve productivity in the verification process than simply making the simulation run faster. One of these is to cut down on the amount of time engineers spend working hands-on with the testbench itself, preparing it and coding Specman/e tests for it. It is common knowledge that the engineer’s task is to stock the testbench with these tests and rerun regressions to measure their effect as they…

Welcome to this, the first blog on The India Circuit (which, as someone cleverly pointed out, can be shortened to “The IC”)! The India Circuit will be about the Indian Electronics System Design & Manufacturing (ESDM) ecosystem.

Are you...

I have written a fair bit recently about electric cars and electric trucks. Note that I'm not talking about autonomous driving, although some of the ADAS technologies are coming along at the same time. The assumption tends to be that the limiting factor...

This event happened a while ago, but I thought it was still topical enough to blog about since there aren’t many events that focus on women engineers. The Grace Hopper Conference is one, and the Society of Women Engineers’ annual conference, called WE...

Have you checked out the new VSR Preset feature and the related forms in the IC6.1.7 and ICADV12.3 releases? We all have heard how automatic routing has significantly reduced the turnaround time for layout designers. VSR Preset is a bonus from Cadence to further reduce the time required. It is a "Jewel in the Crown" of Automatic Routing.

A VSR preset is a simple and user-friendly mechanism…

Today is the 120th anniversary of the discovery of the electron by J.J. Thomson in 1897, for which he received the Nobel prize in 1906. The results were published in Philosophical Magazine 44 (269): pages 293–316. I don't know the precise date of publication...

The Computer History Museum (CHM) is on Shoreline Boulevard in Mountain View in one of the buildings that used to make up the SGI campus back when they were the major force in graphics. Most of the rest of the buildings are now part of the Googleplex...

Cadence introduced its new set of Virtuoso® ADE products, which includes Virtuoso ADE Explorer, Virtuoso ADE Assembler, Virtuoso Variation Option, and Virtuoso ADE Verifier, in the IC6.1.7 and ICADV12.3 releases. It’s really exciting to mention that this next-generation ADE product suite has been well-received by customers all across the globe. This product suite also won the prestigious Product of the Year award…

You hear a lot of talk about autonomous cars, but I've also heard many times that autonomous trucks may well be first. If it costs a fixed amount to make a vehicle autonomous, then it is much easier to absorb that cost into a $150,000 truck than a $20...

Professor Markus Lienkamp, of Technische Universität München (roughly the MIT of Germany) was the only academic who presented at the Automotiv Elektronik Kongress in Ludwigsburg. His presentation was The Status of Electromobility in 2017, or How...

In this week's Whiteboard Wednesdays video, Asila Nahas describes the USB Type-C VIP and goes over the multiple designs the VIP can be used to verify.

Do you have an iPhone? Did it suddenly update IoS at the end of last week? That's because of a vulnerability discovered by a researcher, Nitay Arenstein, in the Broadcom Wi-Fi chip. Since lots of phones, not just iPhone, use this same chip, the vulnerability...
