At the Linley conference last week I ran into Gordon Brebner of Xilinx. He and I go a long way back. We had adjacent offices in Edinburgh University Computer Science Department back when we were doing our PhDs and conspiring to network the department’s Vax into the university network over a two-week vacation. We managed to … Read More
FPGA-based prototyping brings SoC designers the possibility of a high-fidelity model running at near real-world speeds – at least until the RTL design gets too big, when partitioning creeps into the process and starts affecting the hoped-for results.
The average ASIC or ASSP today is on the order of 8 to 10M gates, and that includes… Read More
At the annual Linley Processor Conference this past week a number of chip vendors proposed a raft of new networking solutions directed at solving today’s bandwidth issues. Perhaps the overall highlight of the conference was the recognition by Keynote Speaker Linley Gwennap of the shift that is taking place towards ARM based solutions.… Read More
Altera have been making use of Synopsys’s virtual platform technology to accelerate the time to volume by letting software development proceed in parallel with semiconductor development so that the software development does not need to wait until availability of hardware.
In the past, creating the virtual platform … Read More
In a discussion with one of my PR network recently, I found myself thinking out loud that if the merchant SoC market is getting squeezed hard, that validates something I’ve been thinking – the merchant CPU board market is dying from the middle out.… Read More
As described in DO-254, any inability to verify specific requirements by test on the device itself must be justified, and alternative means must be provided. Certification authorities favor verification by test for formal verification credits because of the simple fact that hardware flies not simulation models. Requirements… Read More
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
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
There are two main approaches to building a substructure on which to do software development and architectural analysis before a chip is ready: virtual platforms and FPGA prototyping.
Virtual platforms have the advantage that they are fairly quick to produce and can be created a long time before RTL design for the various blocks… Read More
AVNET released their 15[SUP]th[/SUP] Xfest this year, a couple of months ago. It was here in Germany last week. It was a well organized event, rich with invaluable technical information and full of decent smart engineers and managers. If you missed it this year register for the next event as soon as you can.
It was a very successful… Read More
