The Rest Is History
By Jon McDonald - 26 Sep, 2013 - Comments: 0

I recently fielded some questions on the evolution of Electronic System Level design. The questions started me thinking about how ESL is being applied today and what effect some of the historical assumptions might be having on ESL’s perceived use cases. It’s interesting that we are at a point to consider historical assumptions about ESL. Looking it up, Wikipedia claims that the term ESL ... » read more

Simple Economics
By Jon McDonald - 25 Apr, 2013 - Comments: 0

By Jon McDonald I was watching one of the MIT OpenCourseWare videos the other day. It was one of the lectures on Computer Science. I believe it was Prof. Robert Gallager who made a statement that really got me thinking: “Increasingly, system computational complexity has little impact on cost because of chip technology.” From a hardware perspective I initially had a bit of trouble with t... » read more

The Best Abstraction
By Jon McDonald - 28 Mar, 2013 - Comments: 0

By Jon McDonald The other day I was asked what would be the best level of abstraction to model at for system-level design. This is a question I get, in one form or another, far too often. It reminds me of an old quote attributed to Lincoln, slightly updated and applied to this subject: “One model can answer some of the questions all of the time, and all of the questions some of the time, but... » read more

Modeling Errors
By Ed Sperling - 28 Feb, 2013 - Comments: 0

Raising the abstraction level in increasingly large and complex design requires proxies. In IC world, we think of them in terms of higher abstractions, but the basic premise is that you can’t focus on ever detail without losing sight of the bigger picture, so we build models that can represent those details. Done well, these models are incredibly useful. They save time, make it easier to ... » read more

TLM-Driven Design And Verification—Time For A Methodology Shift
By Various Writers - 19 Dec, 2012 - Comments: 0

While today’s RTL design and verification flows are a step up from the gate-level flows of two decades ago, RTL flows are straining to meet the demands of most product teams. When designs are sourced and verified at the register transfer level (RTL), IP reuse is difficult, functional verification is lengthy and cumbersome, and architectural decisions cannot be confirmed prior to RTL verificat... » read more

Show Me
By Jon McDonald - 29 Nov, 2012 - Comments: 0

By Jon McDonald Many people—engineers especially, myself included—are naturally biased against change. To get an organization to change takes significant energy. This isn’t a new trend. Much of the sentiment of the camp against change can be summed up by referring back to an 1899 quote from Missouri Sen. Willard Vandiver: “… frothy eloquence neither convinces nor satisfies me. I am f... » read more

Choosing The Right Kite
By Jon McDonald - 27 Sep, 2012 - Comments: 0

By Jon McDonald At my 16-year-old son’s suggestion the two of us have been taking kite-surfing lessons. Last weekend part of the lesson covered the different kinds of kites, how they compare and reasons to use one versus another. One of the points made by the instructor was the need to have different kites for different conditions. It’s such a simple concept, but one that was forgotten ... » read more

Motorcycle Diaries
By Jon McDonald - 26 Jul, 2012 - Comments: 0

By Jon McDonald I recently had reason to add another vehicle to my household. My son is starting to drive, so he's taking my car. Instead of another car I decided to get a motorcycle. I have had a couple, but it's been a few years. After much browsing I decided on a Ducati, I picked it up a few weeks ago. It has an impressive number of user adjustable electronic controls, everything from AB... » read more
