Formal Verification for Post-silicon Debug

Formal Verification for Post-silicon Debug
by Paul McLellan on 08-23-2011 at 5:52 pm

OK, let’s face it, when you think of post-silicon debug then formal verification is not the first thing that springs to mind. But once a design has been manufactured, debugging can be very expensive. As then-CEO of MIPS John Bourgoin said at DesignCon 2006, “Finding bugs in model testing is the least expensive and most desired… Read More

I have talked quite a bit over the last few years about how the trend towards small consumer devices with very fast ramp times. For example, pretty much any time Apple introduces a new product line (iPod, iPhone, iPad…) it becomes the fastest growing market in history. This has major implications for semiconductor design … Read More


Cadence Verification IP Technical Seminar!

Cadence Verification IP Technical Seminar!
by Daniel Nenni on 08-22-2011 at 11:43 am

According to trusted sources it costs upwards of $50M to design a 40nm SoC down to the GDS. Semiconductor IP is a fast growing part of that equation and functional verification of that IP is critical. Hardware complexity growth continues to follow Moore’s Law but verification complexity is even more challenging. In fact, IP verification… Read More

by Daniel Nenni on 08-21-2011 at 4:00 pm

Human nature never ceases to amaze me. I understand the recent economic turmoil and looming National Debt has thrown us for a loop but please, let us all get some perspective here and in the words of Rodney King, “Can we all get along?”

A clever little scumbag recently registered the domain danielnenni.com and is now hawking event … Read More


Apple Will Nudge Prices Down in 2012: PC Market Will Collapse

Apple Will Nudge Prices Down in 2012: PC Market Will Collapse
by Ed McKernan on 08-21-2011 at 7:10 am


Jack Welch, the former CEO of GE, had an edict that each business unit needed to be #1 or #2 in the market or else he sold it off. HP is #1 in PC market share but it is exiting a business that it no longer can control and soon will bleed a lot of cash. HP’s Operating margin is under 6% and falling while Apple’s is at 40% and growing. So the question… Read More

Hewlett-Packard purchased Palm last year for over a billion dollars primarily to get their hands on the WebOS operating system for powering its tablets and smartphones. It’s turned out to be much too little too late. Despite WebOS being a new operating system with many attractive features, HP’s tablet offering, … Read More


Top 5 Reasons for Wasting Power

Top 5 Reasons for Wasting Power
by Paul McLellan on 08-19-2011 at 2:27 pm

Traditionally, David Letterman style, we should really have the top 10 reasons for wasting power in semiconductor design, but here are the five big ones.

Starting with reason #5: Lack of a power gating strategy
Leakage power is a huge proportion of total power and the only way to save leakage power (apart from low leakage cells when… Read More


Design Constraints

Design Constraints
by Paul McLellan on 08-19-2011 at 2:12 pm

Design constraints, which express higher level design intent, are one of the pieces of ancillary data that are critical to the success or failure of a custom (in fact any) design. Design constraints aren’t usually contained within layout files or library information, but without these critical data, designs may not meet specifications.… Read More


Intel’s Back to the Future Buy of Micron

Intel’s Back to the Future Buy of Micron

In an interview that Gordon Moore gave in early 2000, the former co-founder of Intel recounted how they abandoned the DRAM market in the early 1980s in order to exit the increasingly unprofitable business and focus on the promising, yet still young x86 processor market. Intel was also home to EEPROM and NOR Flash, two memory technologies… Read More
