Improving Library Characterization with Machine Learning!

Improving Library Characterization with Machine Learning!
by Daniel Nenni on 12-04-2018 at 7:00 am

For SOC designers that are waiting for library models the saying “give me liberty or give me death” is especially apropos. Without libraries to support the timing flow, SOC design progress can grind to a halt. As is often the case, more than just a few PVT corners are needed. Years ago, corners were what the term sounded like – the 4 corners… Read More


Arm and Mentor Use DesignStart Program to Accelerate Proof-of-Concept for IoT Designs

Arm and Mentor Use DesignStart Program to Accelerate Proof-of-Concept for IoT Designs
by Mitch Heins on 11-15-2017 at 7:00 am

Sometimes the hardest thing about bringing a new idea to fruition is overcoming the inertia to get started with a proof-of-concept. You must be able to put together enough parts of the solution to prove to those controlling budgets that an idea has merit and is worth taking to the next level. It’s a bit of a chick-vs-egg scenario as … Read More


When it comes to High-Sigma verification, go for insight, accuracy and performance

When it comes to High-Sigma verification, go for insight, accuracy and performance
by Michael Pronath on 07-04-2015 at 7:00 am

There are three critical goals that designers of custom digital designs and memories look to achieve with high sigma verification:

(1) obtaining accurate results,
(2) achieving results with good run-time (efficiency), and
(3) gaining proper insight into how their circuit is behaving along with an understanding of failure … Read More

Analog/Mixed-Signal Data Management with Custom Designer
by Majeed Ahmad on 06-30-2015 at 7:00 am

In recent years, a number of technologies as well as the constant desire for faster and more pervasive mobile communication systems have set in motion a well sustained growth trend for the “next big thing” such as the Internet of Things (IoT), wearables, automobile electronics, advances in medical devices etc. In all these areas… Read More


Why did Mentor Acquire Tanner EDA?

Why did Mentor Acquire Tanner EDA?
by Daniel Nenni on 03-09-2015 at 11:30 pm

You have to love when a professional journalist leaks a story and cites a “source close to the acquisition.” News flash: Anyone “close” to the acquisition is under NDA which is a legally binding agreement, not very professional if you ask me. Bloggers however can write whatever they want but since I was actually “close” to … Read More


IC Place and Route for AMS Designs

IC Place and Route for AMS Designs
by Daniel Payne on 11-30-2014 at 7:00 am

High-capacity IC place and route (P&R) tools can cost $200K and more to own from the big three vendors (Cadence, Synopsys, Mentor), but what about IC designs that are primarily Big Analog and Little Digital? In the EDA world we often have multiple choices for tools, and there are affordable alternatives to place and route out… Read More


How to detect weak nodes in a power-off analog circuit?

How to detect weak nodes in a power-off analog circuit?
by Jean-Francois Debroux on 09-01-2014 at 4:00 pm

Most analog cells have a power off mode intended to reduce power consumption. In this mode, all the circuit branches between the supply lines are set in a high impedance mode by driving MOS gates to a blocking voltage. This is a somewhat similar situation to that in tri-state digital circuits.

When a branch is set in that high impedance… Read More


Substrate coupling analysis method and tool

Substrate coupling analysis method and tool
by Jean-Francois Debroux on 08-20-2014 at 4:00 pm

There has been a lot written on this topic, and some expensive tools proposed to solve this issue, but it is still a concern and a mystery for many designers. The point is that whatever efforts you do, the substrate is common to an entire chip and can cause some undesired coupling if not managed properly and at an early stage. As a start… Read More


High Quality PHY IPs Require Careful Management of Design Data and Processes

High Quality PHY IPs Require Careful Management of Design Data and Processes
by Pawan Fangaria on 01-29-2014 at 10:05 am

In last few years IP design has grown significantly compared to the rest of the semiconductor industry. There are newer IP start-ups opening across the world, particularly in India and China. Amid this rush, I wanted to understand the actual dynamics pushing this business and whether all of these IPs follow quality standards. … Read More


MEMS in The World of ICs – How to Quickly Verify?

MEMS in The World of ICs – How to Quickly Verify?
by Pawan Fangaria on 10-29-2013 at 10:00 am

In the modern electronic world, it’s difficult to imagine any system working as a whole without MEMS (Micro-electromechanical Systems) such as pressure sensors, accelerometers, gyroscopes, microphones etc. working in sync with other ICs. Specifically in AMS (Analog Mixed-Signal) semiconductor designs, there can be significant… Read More
