Full-Custom Low Power Design Methodology

Full-Custom Low Power Design Methodology
by Daniel Payne on 05-19-2014 at 1:30 pm

Digital designers have used logic optimization and logic synthesis for decades as a means to produce more optimal designs with EDA tools. On the analog and transistor-level side of design the efforts to automatically optimize for speed or power have generally been limited to circuits with only a handful of transistors. These … Read More


Learning an HDL Simulator

Learning an HDL Simulator
by Daniel Payne on 04-23-2014 at 1:52 am

Learning an HDL language or an HDL simulator are two different things, so I wanted to see what was available for learning a vendor-specific HDL simulator. I’ve already taught Verilog as an instructor using both ModelSim and Active-HDL simulators, however we only used a handful of commands in the class and labs in order to … Read More


Show Me How To Get Better DRC and LVS Results For My SoC Design

Show Me How To Get Better DRC and LVS Results For My SoC Design
by Daniel Payne on 04-14-2014 at 3:30 pm

Most IC engineers learn best by hands-on experience when another more experienced person can show us what to do. If you cannot find that experienced person, then the next best thing is a video from an expert. I was surprised to find out that video was so important today that the #2 most viewed web site on the Internet was www.youtube.comRead More


Dassault Patent on Hierarchy Management

Dassault Patent on Hierarchy Management
by Paul McLellan on 11-05-2013 at 5:05 pm

Dassault have recently been granted a patent on their approach to managing design hierarchy. I asked them how long it took from filing the patent until it was granted and they said the whole process had taken 8 years. It is a bit of an indictment of the patent system when it takes 8 years, also known as 4 or 5 process nodes, for a patent to… Read More


Semiconductor Manufacturing in India?

Semiconductor Manufacturing in India?
by Pawan Fangaria on 09-15-2013 at 11:30 am


Last week I heard about the Indian Cabinet approving the proposal for setting up of two Fabs in India. One led by IBM, Tower Jazzand JP Associates(an Indian business house), and the other led by HSMC(Hindustan Semiconductor Manufacturing Co.), ST Microelectronicsand Silterra. Indian Semiconductor community including IESARead More


Emerging Trend – Choose DRAM as per Your Design Need

Emerging Trend – Choose DRAM as per Your Design Need
by Pawan Fangaria on 09-11-2013 at 7:00 pm

Lately I was studying about new innovations in memory world such as ReRAM and Memristor. As DRAM (although it has become a commodity) has found its extensive use in mobile, PC, tablet and so on, that was an inclination too to know more about. While reviewing Cadence’s offering in memory subsystems, I came across this whitepaperwhich… Read More


Rapid Yield Optimization at 22nm Through Virtual Fab

Rapid Yield Optimization at 22nm Through Virtual Fab
by Pawan Fangaria on 09-09-2013 at 10:00 am

Remember? During DAC2013 I talked about a new kind of innovation: A Virtual Fabrication Platform, SEMulator3D, developed by COVENTOR. Now, to my pleasant surprise, there is something to report on the proven results from this platform. IBM, in association with COVENTOR, has successfully implemented a 3D Virtual Fabrication… Read More


Real Time Concurrent Layout Editing – It’s Possible

Real Time Concurrent Layout Editing – It’s Possible
by Pawan Fangaria on 09-03-2013 at 2:00 pm

Layout editing is a complex task, traditionally done manually by designers, and the layout design productivity largely depends on the designer’s skills and expertise. However, a good tool with features for ease of design is a must. Layout productivity has been an area of focus and various features are constantly being added in… Read More


Reliability sign-off has several aspects – One Solution

Reliability sign-off has several aspects – One Solution
by Pawan Fangaria on 09-01-2013 at 5:00 pm

Here, I am talking about reliability of chip design in the context of electrical effects, not external factors like cosmic rays. So, the electrical factors that could affect reliability of chips could be excessive power dissipation, noise, EM (Electromigration), ESD (Electrostatic Discharge), substrate noise coupling and… Read More
