Simulation Performance Driven By Model Efficiency
By Jon McDonald - 29 Jan, 2015 - Comments: 0

In real estate it’s all about location, location, location. For system level simulation it’s all about performance, performance, performance. I have heard many opinions on the performance of SystemC and TLM simulations: some positive, some negative, much of the opinion based on hearsay or other unreliable information. I believe the performance of the simulation is mainly driven by the model... » read more

A Dream For The Future Of Real System-Level Design Validation
By Guilhem Depelley - 29 Oct, 2014 - Comments: 1

"I have a dream…that one day…all SoCs will be free…of bugs and verifying them will be a walk in the park. I have a dream…that one day…all software engineers will be able to validate their software on pre-silicon hardware at the speed of light, delivering fully functional embedded software “before-on-time” for tape-out. I have a dream today…Well, if not today, how about first ... » read more

How Many Levels Of Abstraction Are Needed?
By Jon McDonald - 23 Oct, 2014 - Comments: 0

Recently I was having a conversation with a user who was creating cycle accurate SystemC models. My initial thought was, "Why would this be necessary?" Through the course of discussions I realized that he did have a design questions that required that level of accuracy and the simulation performance trade-offs were appropriate for his needs. His cycle accurate SystemC models were running at abo... » read more

Designing In The Dark
By Jon McDonald - 25 Sep, 2014 - Comments: 0

While power optimization has received significant focus recently, it is still largely a hidden cost to most hardware and software engineers. A significant problem is the lack of visibility into the impact of decisions while decisions are being made. Often an engineer working on a system will have no practical way of measuring the impact of their design decisions on the system power consumption.... » read more

Not Invented Here Syndrome
By Jon McDonald - 21 Aug, 2014 - Comments: 0

Recently I have made some choices on IP I needed to re-use and some I decided not to re-use. This got me thinking about the general topic of reuse in system-level design. Most will agree with a non-specific statement that reuse is a good thing, but the details tend to be a bit more ambiguous. Clouding the reuse question are occasional infections of NIH Syndrome (Not Invented Here), even if s... » read more

Which Group Should Create System Models?
By Jon McDonald - 26 Jun, 2014 - Comments: 0

One of the factors affecting adoption of a system-level flow is identifying who will do the work to create the system model. For most organizations it's not something they have allocated to a specific group. Generally when an ESL flow is deployed, the software developers, architects and hardware designers will all benefit from the investment, so it would be reasonable that they all contribut... » read more

Is The Definition Of IC Reliability Changing?
By Matthew Hogan - 18 Jun, 2014 - Comments: 1

“You know, brain surgery's not difficult if you don't care whether the person dies, it's actually quite easy. Flying a plane is quite easy if you don't mind crashing. That's what hard means. It's an expression of how much you care about the result. And if you are proud of it, or you believe it can be good and you want it to be good, then it can be sort of infinitely hard, to the point where i... » read more

Commoditizing Our Kids
By Jon McDonald - 27 Mar, 2014 - Comments: 0

My son is graduating from high school this year. He’ll be starting on an engineering degree in the fall. Thinking about the outlook he will face reminds me of questions and comments I have received from customers and colleagues at various points. In my mind these thoughts reduce to a simple question: Is engineering skill becoming a commodity? From Wikipedia: “The exact definition of th... » read more

What You Can Learn From Robots
By Jon McDonald - 30 Jan, 2014 - Comments: 0

My sons are in the robotics club at their high school. They program a small robot to perform simple tasks to score points in a competition. It’s a great way for them to learn about embedded systems and stimulate their interest in technology. While looking for ways to help them improve their understanding of embedded systems we started going through some of the online material, one of the c... » read more

Plans Vs. Planning
By Jon McDonald - 20 Dec, 2013 - Comments: 0

The end of the year is a good time to look back at what’s happened over the past year, and look ahead to what might happen in the coming one. Two quotes that help my thought process when thinking about the might be coming, “Change is the law of life.” from Kennedy, and “Plans are nothing, but planning is indispensable” from Eisenhower. From my perspective, 2013 has been a good year... » read more
