Power-Aware Debug to Find Low-Power Simulation Bugs

Power-Aware Debug to Find Low-Power Simulation Bugs
by Daniel Payne on 09-09-2016 at 12:00 pm

When I worked at Intel designing custom chips my management would often ask me, “Will first silicon work?” My typical response was, “Yes, but only for the functions that we could afford to simulate before tape-out.” This snarky response would always cause a look of alarm, quickly followed by a second … Read More

I’ve owned and used many generations of cell phones, starting back in the 1980’s with the Motorola DynaTAC phone and the biggest usability factor has always been the battery life, just how many hours of standby time will this phone provide and how many minutes of actual talk time before the battery needs to be recharged… Read More

Process Development, CAD and Circuit Design
by Daniel Payne on 04-29-2016 at 7:00 am

Working at Intel as a circuit designer I clearly remember how there were three distinct groups: Process Development, CAD and Circuit Design. Each of the groups sat in a different part of the building in Aloha Oregon, we had different job titles, different degrees, spoke with different acronyms and yet we all had to work together … Read More


Custom IC Design Flow with OpenAccess

Custom IC Design Flow with OpenAccess
by Daniel Payne on 03-18-2016 at 12:00 pm

Imagine being able to use any combination of EDA vendor tools for schematic capture, SPICE circuit simulation, layout editing, place & route, DRC, LVS and extraction. On the foundry side, how about creating just a single Process Development Kit (PDK), instead of vendor-specific kits. Well, this is the basic premise of a recent… Read More

IC Design and OpenAccess
by Daniel Payne on 03-06-2016 at 12:00 pm

EDA vendors have long used proprietary file and database formats to keep their users locked into their specific tool flow and keep any competitors from sharing in the IC design process. Along the way the actual users of EDA tools have often requested and helped to create interoperable flows so that they could mix and match multiple… Read More


Learning about 3D Integration of ICs and Systems

Learning about 3D Integration of ICs and Systems
by Daniel Payne on 10-15-2015 at 4:00 pm

We blog a lot about Moore’s Law, and even “More than Moore” where 3D integration of ICs and systems are used to get lower product costs. One big challenge with 3D integration of ICs is that most EDA software was really intended only for abstracting at 2D or 2.5D structures. Over the past several years there have … Read More

Do you remember how auto maker Toyota had to pay a $1.2 billion settlement in 2014 because some of their automotive models experienced sudden, unintended acceleration? That scenario has to be an engineer’s worst nightmare because something was missed during the design and testing of an automotive electronics system that… Read More


How ARM Implemented a Mali GPU using Logic Synthesis and Place/Route Tools

How ARM Implemented a Mali GPU using Logic Synthesis and Place/Route Tools
by Daniel Payne on 07-17-2015 at 12:00 pm

ARM is a well-known semiconductor IP provider and they often create a reference design so that SoC companies can have a starting point to work with. On the GPU side of IP the ARM engineers have an architecture called Mali, and a recent webinar hosted by Synopsys reviewed how the physical design area was minimized by using a combination… Read More


Tackling Layout Gradient Effects in 16 nm FinFET using Layout Automation

Tackling Layout Gradient Effects in 16 nm FinFET using Layout Automation
by Daniel Payne on 07-10-2015 at 12:00 pm

My first exposure to automating IC layout was back in the 1980’s at Intel where I coded a layout compiler to auto-generate about 6% of a graphics processor chip. The need to use automation for IC layout continues today, and with the advent of FinFET technology there are some new challenges like layout gradient effects that … Read More
