What I Learned About System Design Enablement at DesignCon

By tomhackett | 9 Feb 2018

While attending the recent DesignCon show for the first time, I was struck by the many displays of cables, connectors, boards, and various kinds of test equipment (you can read about the impact this had on me in my previous post, A Walk Through DesignCon Turns Into a Long Journey ). There was so much hardware, in fact, that I felt like I was walking through a giant Fry’s store. The impression was so strong that my first...

A Walk Through DesignCon Turns Into a Long Journey

By tomhackett | 9 Feb 2018

Have you ever attended the DesignCon show? I attended the recent event for the first time and was surprised by what I saw: tons of high-bandwidth coax cables, circuit boards, connectors, and other hardware—all harnessed to very expensive scopes and channel analyzers displaying perfect eye diagrams. This was definitely a show for hardware engineers. Walking around the show floor brought on an unexpected feeling...

New AMBA 5 ACE/AXI Specification: Rationale for Atomic Transactions

By DimitryP | 1 Feb 2018

The recent update of the AMBA® 5 ACE/AXI specification introduces a number of significant performance improvements which help to align the protocol to the more recent AMBA® 5 CHI (Coherent Hub Interface) specification. One of the most prominent features is introduction of atomic transactions. Before we take a close look at this new class of transactions, let’s look back in time. Previous generations of AMBA ACE/AXI...

You Won't Believe Your Ears When Listening to Your Laptop

By PaulaJones | 31 Jan 2018

I wouldn't believe it if I hadn't heard it myself on a laptop in the Cadence booth at the Consumer Electronics Show ( CES) this year. Through a great innovation by our partner Dolby, you can now get surround sound on your laptop! You’ve probably been in a movie theater with Dolby’s latest innovation— Dolby Atmos . And maybe you’ve purchased a television in the last year with Dolby Atmos (it was a huge sensation at...

JEDEC UFS 3.0 Now Available in Cadence VIP Portfolio – For Mobile and Automotive Markets

By Thierry Berdah | 29 Jan 2018

The JEDEC UFS (Universal Flash Storage) started in 2011 with the v1.0 first specification version, supporting a bandwidth of 300 MB/s per lane. Since then JEDEC has been continuously releasing new UFS specification versions on top of the MIPI UniPro® and MIPI MPHY® evolving specs. UFS is now evolving to a new version of 3.0, reaching a total bandwidth of 2.4 GB/s. It seems that UFS keeps on slowly winning over eMMC in...

CCIX Coherency: Verification Challenges and Approaches

By DimitryP | 24 Jan 2018

Cache coherency is not a new concept. Coherent architectures have existed for many generations of CPU and Interconnect designs. Verifying adherence to coherency rules in SoCs has always been one of the most complex challenges faced by verification engineers. Over the years, it became even more challenging with increasing number of cores in CPU clusters and introduction of the embedded L3 (level 3) cache to the coherent...

USB 3.2—The USB Type-C Connector Finally Met its Match

By Jacek Duda | 19 Sep 2017

It’s only a week before the first event of USB Developer Days , a series of meetings for USB developers, where the USB 3.2 specification will be formally announced. Much like with any recent smartphone announcement, we know pretty much everything about the new standard before it’s formally announced. We know that the big news is the 20Gbps support, twice the performance of the previous (USB 3.1 Gen 2) standard, which...

Here’s an experiment to try: in a quiet (but crowded) Auditorium, drop a stack of plates. Hypothesis: At the first splinters of the crash, all eyes will jerk to the source of the sound. You probably won’t get many people listening harder to find out what happened. Yes, our hearing can give us a lot of information, too—it can indicate direction, distance, magnitude, and even give some ideas about what happened ...

Happy Birthday Tensilica

By PaulaJones | 31 Jul 2017

Yes, it’s Tensilica’s birthday! Twenty years ago today, on July 31, 1997, Tensilica was officially incorporated by Chris Rowen, who I knew from our Synopsys days when he was VP of the Design Reuse Business Unit. I started working with Tensilica (as a PR consultant) when there were eight people in the office next to the Duke of Edinburgh pub on Wolfe road in Cupertino. I became a Tensilica employee in 2002, and worked...

Have you tried a product incorporating the new USB Type-C port? Do you wonder how well it works? I recently bought a new laptop and monitor that support this interface. In fact, Type-C is the only port on those devices. Image courtesy Austin Event Photography I’ve been looking forward to the promise of a single, all-encompassing port ever since I wrote Why USB 3.0 Will Drive SoC Verification back in 2013. Well...

Memory Trends for Automotive Markets

By Priyab | 8 Mar 2017

Remember automobiles from a few years ago? They were pretty simple machines with lots of small microprocessors distributed across the whole vehicle and doing fairly simple tasks. Semiconductors have been in automobiles for several years, of course, with simple 8- and 16-bit microcontrollers performing functions like Anti-lock Braking (ABS). But today’s automobiles are a different beast. They incorporate several compute...

Bluetooth 5: Making Your Smart Home a Reality

By Priyab | 5 Dec 2016

We all know the futuristic vision of the world just around the corner. The vision where we tell our smart home that we’ve just left work at the end of a long day, and we’re heading home. Our home then tells the thermostat to warm up or cool down, lights to turn on, and the oven to start baking the lasagna we left in it that morning. We arrive to a warm, brightly lit home, and hot, freshly cooked food. You’ve got the...

Do you remember what life was like before the internet and smart phones? If you wanted to find information about something, you had to go to the library and find a book that could answer your question, which usually meant a delay of anything from a few hours to several days. Then the internet happened, and the world as we know it changed forever. Smart phones came along, and brought with them a new kind of freedom and...

A Winning Strategy: Ethernet 10Base-T to Ethernet 400G!

By annkeffer | 3 Oct 2016

Ethernet was developed in the 1970s and has been a viable communications protocol for over 40 years. Ethernet was initially used to connect computer systems and peripherals in a local area network (LAN) but quickly evolved to be the protocol of choice for wide area networks (WANs) and of course, the internet. It’s been constantly reinvented, with new capabilities, more security, and faster speeds over the years to keep...
