When A Lot May Not Be Enough


For the last couple of months my son has been trying to save for a Nintendo Switch. The emphasis here is on “trying to.” The problem is that whenever he amasses enough money to buy something else, he tends to spend the money on a cheaper toy like a new Lego Dimensions figure. I guess that delayed gratification isn’t really a strength of my son. His assumption is that the best way to colle... » read more

Come Together Right Now Over… Virtual Prototypes


As a frequent traveler and gadgets enthusiast I love the concept of all my devices being connected. However, more often than not I experience a divide which is sometimes caused by bad software and sometimes caused by missing hardware interfaces. My recent frustration was related to my tablet missing a USB port to upload new maps to my GPS device. The GPS device became a divided, isolated pi... » read more

Verification And Validation Don’t Mean The Same Thing


While often used intermixed, verification and validation are quite different procedures with different goals and different means to achieve those goals. No better way to clear up the confusion by starting with some definitions as stated by Wikipedia, https://en.wikipedia.org/wiki/Verification_and_validation: “Verification is intended to check that a product, service, or system (or porti... » read more

Wear Down Your Virtual Prototype


Just when you think you know all variations of embedded software development you are exposed to another domain of unique and interesting challenges. This happened to me awhile back when I started to learn about the software for Flash Memory controllers. You can read a lot about Flash market growth predictions or about the physical challenges of the next generation storage technologies he... » read more

Learn From The Experts


I visited SNUG Silicon Valley last week. This annual Synopsys User Group event at the Santa Clara Convention Center is always a good way to get in touch with the end users of various EDA products. I attended the technical track with experts from ARM, NVIDIA, Intel and Synopsys, who talked about their experience in accelerating software development, hardware verification and system validation... » read more

Software Modeling And KPI


In Software Modeling Goes Mainstream, Ed Sperling recently wrote how chipmakers are applying use case modeling techniques to better understand the interactions between software and hardware and how they impact system performance and energy efficiency. As the software content for multicore SoCs grows, these interactions are becoming increasingly complex. For system designers and SoC architect... » read more

It Feels Like Magic


Over the holidays I visited Universal Studios in Los Angeles with my family. The entire park is full of high tech so-called 4D rides as they add motion and other effects, like spraying water when someone sneezes, to a 3D movie. We were, for example, able to experience what it would be like if a bus gets caught in between King Kong and a t-rex fighting with each other. Despite a wide range of... » read more

Virtual Iron (Chef)


I love good food but I am a horrible cook. Partially because my wife is a wonderful chef at home and I can enjoy the comfort of just eating. Until recently, I couldn’t handle most of the kitchen equipment and I had no clue which ingredients and spices work well together. When I read cooking recipes my brain started to freeze and I felt completely clueless. This was nagging me at times and... » read more

The Right Kind Of Fun


A couple of weeks ago I went to see “Together Again At Last…For The Very First Time” by John Cleese and Eric Idle at the Center for the Performing Arts in San Jose. I hope all of you recognize both gentlemen as two members of Monty Python. As you can imagine, it was quite an exciting night. With the audience being Monty Python fanatics, every video clip or skit was received with a lot ... » read more

Fast, Accurate, And Standards-Based


Unlike the loosely timed models used for software development, which rely on a high level of abstraction to simulate as fast as possible, the communication between the architecture models in a virtual prototype for early performance analysis requires timing to be modeled more accurately. This tradeoff can seem like a big leap to some, spanning the gap from SystemC TLM-2.0 LT (loosely timed) ... » read more
