Why is Low Frequency Noise Measurement for ICs Such a Big Deal?

Why is Low Frequency Noise Measurement for ICs Such a Big Deal?
by Daniel Payne on 09-27-2016 at 12:00 pm

Even digital designers need to be aware of how noise impacts their circuits because most clocked designs today use a Phase Locked Loop (PLL) block which contains a circuit called a Voltage Controlled Oscillator (VCO) that is quite sensitive in operation to the effects of noise and process variation. As process node scaling continues… Read More


Getting out of DIY Mode for Virtual Prototypes

Getting out of DIY Mode for Virtual Prototypes
by Don Dingee on 09-26-2016 at 4:00 pm

Virtual prototyping has, inexplicably, been largely a DIY thing so far. Tools and models have come from different sources with different approaches, and it has been up to the software development team to do the integration step and cobble together a toolchain and methodology that fits with their development effort.

That integration… Read More


Mentor Webinar on Power Exploration for Optimizing Power

Mentor Webinar on Power Exploration for Optimizing Power
by Bernard Murphy on 09-23-2016 at 8:00 pm

There are a lot of clever techniques to automatically find and even implement methods for register gating and memory gating, but the bulk of power-saving still depends on designer and architect insight based on expected range of use of a device, complemented by practical use-case simulations. Of course this team needs to be able… Read More


RTL Design Restructuring Explained

RTL Design Restructuring Explained
by Daniel Payne on 09-22-2016 at 4:00 pm

Modern SoC designs can use billions of transistors where transistors are grouped into gates, then gates grouped into cells, then cells grouped into blocks, blocks grouped into modules, and so on, creating a complex hierarchy. What a front-end designer conceives of logically for a hierarchy will differ from how an optimized physical… Read More


Solutions for Variation Analysis at 16nm and Beyond

Solutions for Variation Analysis at 16nm and Beyond
by Tom Simon on 09-22-2016 at 7:00 am

Variation is still the tough nut to crack for advanced process nodes. The familiar refrain of lower operating voltages and higher performance requirements make process variation an extremely important design consideration. As far back as the early 2000’s design teams have been looking for a better approach to model variation… Read More


3 Small-Team Design Productivity Challenges Managed

3 Small-Team Design Productivity Challenges Managed
by Don Dingee on 09-21-2016 at 4:00 pm

“Data management tools? We use small teams doing small designs. Each project only has two or three designers. Everyone uses the same EDA tools. Why do we need another tool for collaboration?” Good question. If you enjoy frequent meetings and redoing work because someone didn’t understand the status of IP blocks, the answers may… Read More


Low Power Design – a Server Perspective (Webinar)

Low Power Design – a Server Perspective (Webinar)
by Bernard Murphy on 09-21-2016 at 7:00 am

Most of what you have read about design for low power has probably focused on mobile devices where power consumption constraints tend to outweigh performance objectives. These devices use aggressive power switching strategies, based on the reasonable assumption that parts or all of the device can be powered down at any given … Read More

Next Book Signing: Linley Processor Conference 2016!
by Daniel Nenni on 09-20-2016 at 12:00 pm

It is a busy month for book signings but it is a pleasure to do it for the greater good of the semiconductor industry. It really is an honor to meet the people who keep our electronic devices on the leading edge of technology, absolutely.

The Linley Processor Conference is on September 27[SUP]th[/SUP]and 28[SUP]th[/SUP] at the Hyatt… Read More


Up front phases improve CDC analysis

Up front phases improve CDC analysis
by Don Dingee on 09-19-2016 at 4:00 pm

Many tools find clock domain crossings (CDCs) in FPGA designs. Some don’t find the right ones since they don’t comprehend things like in-house synchronizer constructs. Some find too many based on misunderstanding intent, inaccurate constraints, and other factors that lead to noise.… Read More

FREE Fabless: The Transformation of the Semiconductor Industry!
by Daniel Nenni on 09-19-2016 at 12:00 pm

As most of you know SemiWiki published a book which is a really nice history of the fabless semiconductor ecosystem. Thousands of people have copies, we have received many compliments on it, and we are very proud. As a thank you to all SemiWiki members I would like to offer a free electronic version of the book (PDF). You can access it… Read More
