Increasingly the challenge with SoCs, especially for mobile, is not getting the performance high enough but doing so in a power-efficient manner. Handheld devices running multiple apps need high-speed processors that consume extremely low levels of power both in operating and standby modes. In the server farm, the limit is … Read More





Apple’s Victory Will Re-Shuffle the Semi Industry
Apple’s legal victory over Samsung has been analyzed in thousands of articles and TWEETs since last Friday’s announcement and surely more will follow. Most of the commentary has focused on the first order impact to handset manufacturers. It is not entirely clear how it will all settle but there are sure to be secondary ramifications… Read More
A Brief History of FPGAs
From the transistor to the integrated circuit to the ASIC, next comes programmable logic devices on the road to the mainstream fabless semiconductor industry. PLDS started in the early 1970’s from the likes of Motorola, Texas Instruments, and IBM but it wasn’t until Xilinx brought us the field programmable gate array (FPGA)… Read More
SpringSoft Laker vs Tanner EDA L-Edit
Daniel Payne recently blogged some of the integration challenges facing Synopsys with their impending acquisition of SpringSoft. On my way back from San Diego last week I stopped by Tanner EDA to discuss an alternative tool flow for users who find themselves concerned about the Laker Custom Layout road map.
Design of the analog… Read More
IP Wanna Go Fast, Core Wanna Not Rollover
At a dinner table a couple years ago, someone quietly shared their biggest worry in EDA. Not 2GHz, or quad core. Not 20nm, or 450mm. Not power, or timing closure. Call it The Rollover. It’s turned out to be the right worry.
Best brains spent inordinate hours designing and verifying a big, hairy, heavy breathing processor core to do … Read More
A Brief History of ASIC, part II
All semiconductor companies were caught up in ASIC in some way or another because of the basic economics. Semiconductor technology allowed medium sized designs to be done, and medium sized designs were pretty much all different. The technology didn’t yet allow whole systems to be put on a single chip. So semiconductor companies… Read More
Book Review: Mixed-Signal Methodology Guide
Almost every SoC has multiple analog blocks so AMS methodology is an important topic to our growing electronics industry. Authored by Jess Chen (Qualcomm), Michael Henrie (Cliosoft), Monte Mar (Boeing) and Mladen Nizic (Cadence), the book is subtitled: Advanced Methodology for AMS IP and SoC Design, Verification and Implementation… Read More

ARM + Broadcom + Linux = Raspberry Pi
Broadcom has designed an impressive SOC named the BCM2835 with the following integrated features:
- ARM CPU at 700MHz
- GPU – VideoCore IV
- RAM – 256 MB
The British chaps at Raspberry Pi have created a $35.00 Linux-based computer based on the Broadcom BCM2835 chip that is tiny in size but big in utility:… Read More
Debugging Subtle Cache Problems
When I worked for virtual platform companies, one of the things that I used to tell prospective customers was that virtual prototypes were not some second-rate approach to software and hardware development to be dropped the moment real silicon was available, that in many ways they were better than the real hardware since they had… Read More
