Correlating Software Execution With Switching Activity To Save Power In SoC Designs
By Russell Klein - 09 Mar, 2017 - Comments: 0

There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more

Finding The Unexpected In High Performance Designs
By Russell Klein - 09 Feb, 2017 - Comments: 0

It was growing dark as I drove a winding road on Mt. Hood, deep in the American northwest forest. The firs were thick, creating a lot of shadows and making it tough to see things clearly. Then out of the corner of my eye, I swear I saw a 10-foot “man” covered with brown fur. It looked a lot like a Wookie. But everyone knows Wookies aren’t real. It had to be Bigfoot! I slammed on th... » read more

Finding Evasive System-Level Bugs Using Memory Consistency Algorithm
By Russell Klein - 12 Jan, 2017 - Comments: 0

Over Easter weekend in 2015 there was a jewelry heist at the safe deposit building at Hatton Gardens in London. The safe deposit vault was in the basement of a building and is used by jewelers in the area for storing large amounts of diamonds, jewelry, precious metals, and cash. The thieves made off with over $300 million in loot, making it the biggest heist in British history. For a while it l... » read more

Five Pitfalls In PCIe-Based NVMe Controller Verification
By Saurabh Sharma - 08 Dec, 2016 - Comments: 1

Non-Volatile Memory Express (NVMe) is gaining rapidly in mindshare among consumers and vendors. Some industry analysts are forecasting that PCIe-based NVMe will become the dominant storage interface over the next few years. With its high-performance and low-latency characteristics, and its availability for virtually all platforms, NVMe is a game changer. For the first time, storage devices and ... » read more

Need Emulation Now? You’ve Got It
By Vijay Chobisa - 10 Nov, 2016 - Comments: 0

Did you know that the way companies use hardware emulation has changed? Until recently, companies had no choice but to house their emulators in a lab and hard wire them (using lots of wires) to other supporting hardware and workstations dedicated to a single project at a time. The emulator and its set up was accessible to users at only that location and switching between projects was difficu... » read more

Deterministic ICE App Tackles ICE Limitations
By Rizwan Farooq - 13 Oct, 2016 - Comments: 0

Historically, SoC verification has used In-Circuit Emulation (ICE) to exercise the design under test (DUT) by connecting physical targets to an emulator. ICE delivers the advantage of being able to run real-world usage scenarios before tape-out. However, an ICE-based verification environment is hampered by several inherent limitations. It is restricted to trigger- and waveform-based debug. W... » read more

The 2016 Wilson Research Group Functional Verification Study
By Harry Foster - 08 Sep, 2016 - Comments: 0

I am writing a series of blogs that presents the findings from our new 2016 Wilson Research Group Functional Verification Study. Similar to my previous 2014 Wilson Research Group functional verification study blogs, I plan to begin this set of blogs with an exclusive focus on FPGA trends. Why? For the following reasons: Some of the more interesting trends in our 2016 study are related to F... » read more

Optimizing Emulator Utilization
By Russell Klein - 11 Aug, 2016 - Comments: 0

The growing pressures of market schedules, design complexity and the ever-increasing amount of embedded software in today’s SoCs has put verification in the hot-seat. Now that new emulation tools can link hardware and software verification, SoC designers are turning to emulation more than ever before to debug embedded software. The standard method for debugging software with an emulator is wi... » read more

Addressing The Challenges Of Automotive Motor Control
By Ahmed Eisawy - 14 Jul, 2016 - Comments: 0

By Andrew Talan and Ahmed Eisawy As you leave work today and enter the parking lot, you hit the unlock button on your car remote. Using the power lift to open the hatch back, you put your laptop bag in the back of the car. While seated in the car, you adjust your seat position and bump your driver-side mirror into a new position and then head for home. You probably don’t think much about y... » read more

The Secret to Reaching Rapid Verification Closure
By Ellie Burns - 16 Jun, 2016 - Comments: 0

Every design team is looking to reduce RTL verification time in order to meet aggressive schedules. Successful teams have moved their level of design abstraction up to the C++ or [gettech id="31018" comment="SystemC"] level and employ [getkc id="105" comment="high-level synthesis"] (HLS) within their design flow. By taking advantage of this high-level description, these teams also plug into int... » read more
