Noise Coupling

Noise Coupling
by Paul McLellan on 10-24-2011 at 8:47 am

One of the challenges of designing a modern SoC is that the digital parts of the circuit are really something that in an ideal world you’d keep as far away from the analog as possible. The digital parts of the circuit generate large amounts of noise, especially in the power supply and in the substrate, two areas where it is impossible… Read More

There are lots of places that Apache is going to popping up in the next few weeks.

Firstly, Andrew Yang will deliver the keynote on October 24th at the Electrical Performance of Electronic Packaging and Systems (EPEPS) in San Jose. He will be talking about “Chip-Package-System convergence: bridging multiple disciplings… Read More

Austin and San Jose SCC
by Paul McLellan on 10-14-2011 at 3:35 pm

Don’t forget the SpringSoft Community Conferences next week in Austin on Tuesday and in San Jose on Thursday. There is no charge and you even get a free lunch (see “no such thing as…”).

The morning in Austin is focused on functional closure and how to leverage SpringSoft’s verification technology… Read More

If you are a user of Jasper’s products then you should definitely plan to attend. This year there is so much good material that the meeting… Read More


SoC Realization: Let’s Get Physical!

SoC Realization: Let’s Get Physical!
by Paul McLellan on 10-05-2011 at 1:41 pm

If you ask design groups what the biggest challenges are to getting a chip out on time, then the top two are usually verification, and getting closure after physical design. Not just timing closure, but power and area. One of the big drivers of this is predicting and avoiding excessive routing congestion, which is something that … Read More


Verdi: there’s an App for that

Verdi: there’s an App for that
by Paul McLellan on 10-03-2011 at 5:58 am

Verdi is very widely used in verification groups, perhaps the industry’s most popular debug system. But users have not been able to access the Verdi environment to write their own scripts or applications. This means either that they are prevented from doing something that they want to do, or else the barrier for doing it is… Read More


Introducing TLMCentral

Introducing TLMCentral
by Paul McLellan on 09-29-2011 at 8:00 am

Way back in 1999 the open SystemC initiative (OSCI) was launched. In 2005 the IEEE standard for SystemC (IEEE1666-2005 if you are counting) was approved. In 2008, TLM 2.0 was standardized (transactional level models), making building virtual platforms using SystemC models easier. At least the models should be play nicely together,… Read More


Battle of the Patents

Battle of the Patents
by Paul McLellan on 09-27-2011 at 5:01 pm

What’s going on in all these wireless patent battles? And why?

The first thing to understand is that implementing most (all?) wireless standards involves infringing on certain “essential patents.” The word “essential” means that if you meet the standard, you infringe the patent, there is no way around it. You can’t build a CDMA… Read More


Magma eSilicon One Keynote

Magma eSilicon One Keynote
by Paul McLellan on 09-27-2011 at 2:31 pm

I was at the first half of Magma’s Silicon One event yesterday. The first keynote was by Rajeev about the environment for SoC designs, especially fabless startups, and Magma’s role going forward. More about that later. The other keynote was Jack Harding, CEO of eSilicon. As usual Jack did his presentation without … Read More
