When Ethernet was introduced in 1983 it ran at 10Mbps and mostly relied on hubs and coaxial cable. Twelve years later a faster speed was introduced, running at 100Mbps. Since then we have seen an acceleration of new data rate introductions. According top the Ethernet Alliance, Ethernet could have 12 speeds before 2020, with 6 of … Read More

When most people talk about the IoT, it is usually all about wearables-this and low-power-that – because everyone is chasing the next huge consumer post-mobile device market. Mobile devices have provided the model. The smartphone is the on-ramp to the IoT for most consumers, with Bluetooth, Wi-Fi, and LTE, and maybe a dozen or … Read More

Ethernet is suddenly a hot topic in SoC design again. The biggest news may be this: it’s not just the cloud and enterprise networks. Those are still important applications. The cloud is driving hard for more ports at 25G server and 100G switch speeds according to a recent Dell’Oro Group report. Enterprise networks are driving for… Read More


Power Analysis Needs Shift in Methodology

Power Analysis Needs Shift in Methodology
by Pawan Fangaria on 07-26-2015 at 7:00 am

It’s been the case most of the time that until we hit a bottleneck situation, we do not realize that our focus is not at the right spot. Similar is the case with power analysis at the SoC level. Power has become equally if not more important than the functionality and other parameters of an SoC, and therefore has to be verified earlier … Read More

How PowerArtist Interfaces with Emulators
by Pawan Fangaria on 07-16-2015 at 5:00 pm

Last month in DAC I could see some of the top innovations in the EDA world. EDA is a key enabler for advances in semiconductor designs. Among a number of innovations worth mentioning (about which I blogged just after DAC), the integration of Mentor’s Veloce with ANSYS’ PowerArtist for power analysis of live applications caught my… Read More


Eyes Meet Innovations at DAC

Eyes Meet Innovations at DAC
by Pawan Fangaria on 06-14-2015 at 7:00 am

It gives me a very nice, somewhat nostalgic, feeling after attending the 52[SUP]nd[/SUP] DAC. There was a period during my final academic year in 1990 and my first job when I used to search through good technical papers in DAC proceedings and try implementing those concepts in my project work. In general, representation from ‘R&D… Read More


Getting the Best Dynamic Power Analysis Numbers

Getting the Best Dynamic Power Analysis Numbers
by Daniel Payne on 05-27-2015 at 1:00 pm

On your last SoC project how well did your dynamic power estimates match up with silicon results, especially while running real applications on your electronic product? If your answer was, “Well, not too good”, then keep reading this blog. A classical approach to dynamic power analysis is to run your functional testbench… Read More


Virtual Emulation Extends Debugging Over Physical

Virtual Emulation Extends Debugging Over Physical
by Pawan Fangaria on 12-13-2014 at 7:30 am

Amid burgeoning complexity of SoC verification with ever increasing hardware, software and firmware content, verification engineers are hard pressed with learning multiple tools, technologies and methodologies and still completing SoC verification with full accuracy in time. The complexity, size and diversity of SoC … Read More


Improving Verification by Combining Emulation with ABV

Improving Verification by Combining Emulation with ABV
by Tom Simon on 10-30-2014 at 4:00 pm

Chip deadlines and the time to achieve sufficient verification coverage run continuously in a tight loop like a dog chasing its tail. Naturally it is exciting when innovative technologies can be combined so that verification can gain an advantage. Software based design simulators have been the mainstay of verification methodologies.… Read More


A Brief History of Functional Verification

A Brief History of Functional Verification
by Paul McLellan on 04-13-2014 at 3:00 pm

Usually these brief history pieces are totally written by the SemiWiki blogger whose name is at the top. Often me since that was how I prototyped book chapters (buy). Well, OK, I did actually write this but it is completely cribbed from a presentation earlier this week by Wally Rhines who gave a sort of keynote at the announcement of… Read More
