Applications for IoT sensors are becoming more sophisticated, especially for industrial usage. Building optimal sensors for different applications requires multi-domain design, optimization and verification flows. The sensor devices are usually MEMS, and as such have electrical properties that need to be tailored to … Read More
Physically Aware DFT Improves PPA
Introducing on-chip test circuitry has become a necessary criteria for an ASIC’s post manufacture testability. The test circuitry is usually referred as DFT (Design-for-Test) circuit. A typical methodology for introducing DFT circuit in a design is to replace usual flip-flops with special types of flip-flops called ‘scan… Read More
Cadence 2014 Results
Cadence announced their Q4 and 2014 results yesterday. They are the only one of the big 3 EDA companies whose fiscal year is the calendar year so Synopsys and Mentor will not be joining them in announcing them this week.
I won’t go into the numbers in detail, you can find them all easily enough. But it is a pity that statements like… Read More
Temperature Monitoring IP to Revamp SoCs
With increasing density and functionality of chips at extremely thin silicon and metal layers, temperature has become critical. The temperature situation can become worse with wireless enabled 24/7 power-on devices. In such a scenario, a device must manage its thermal profile dynamically to keep the temperature within tolerable… Read More
Sigrity Focuses on LPDDR4 Compliance Analysis in 2015 Release
It was back in July of 2012 that the acquisition of Sigrity by Cadence was announced. Although Cadence is a dominant player in both IC and board layout tools, they did not have an electromagnetic (EM) signal integrity solution in their portfolio. This acquisition marks a turning point for the EM/SI sector – tight integration… Read More
Verification of Wireless RFIC Designs
Wireless technology is all around as I use cellular on an Android phone, WiFi to connect my MacBook Pro to the internet, Bluetooth for a headset, ANT+ for my cycling computer, and NFC to speed up electronic payments on the Android phone. Here’s a big picture look at some of the modern wireless standards available to choose from:… Read More
Customizable IP for HP and LP Audio Subsystems
Today, Smartphones and mobile devices have become center of innovation with multiple functions getting into them. Considering the audio or voice application, there can be multi-way conferencing, video chat, complete audio/video streaming, gaming, voice triggering and recognition,… you name an application, and it will … Read More
HiFi Sounds Better than Ever
If you think that the sound atmosphere created by Dolby or Surround–sound audio is the best you can achieve today by using complexes algorithms on DSP, like I thought before knowing about “Object-Based Audio”, you must read these lines! In fact Surround-sound Audio is limited by the number of speakers installed in a room, or a car,… Read More
Ensuring Safety Distinctive Design & Verification
In today’s world where every device functions intelligently, it automatically becomes active on any kind of stimulus. The problem with such intelligence is that it can function unfavorably on any kind of bad stimulus. As the devices are complex enough in the form of SoCs (which at advanced process nodes are more susceptible to … Read More
An Approach to Top-Down SoC Verification
We’ve blogged dozens of times about UVM– Universal Verification Methodology at SemiWiki, and all of the major EDA vendors support UVM, so you may be lulled into thinking that UVM is totally adequate for top-down SoC verification. Yesterday I had a phone discussion with Frank Schirrmeister of Cadence about a new approach… Read More
