Reliability vs Robustness

Posted by Mike Jensen

Mike Jensen

If a system is reliable, is it also robust? And is the converse also true: does a robust system have to be reliable? The answers are no and yes. A reliable system performs its intended function when conditions are nominal. As long as design details and environmental conditions remain stable, you can count on a reliable system to do its job time after time. But what happens if these same design details

Wow Factor

Posted by Mike Jensen

Mike Jensen I have mentioned in earlier posts that one of my responsibilities on the SystemVision team is teaching training classes. If users want formal SystemVision or VHDL-AMS training, I am usually the instructor. It is fun and occasionally gets me out of my office for a few days. Because SystemVision is such a flexible modeling and analysis environment with a broad range of applications (think mixed-signal … Read More

Engineering Oops!

Posted by Mike Jensen

Mike Jensen Awhile back I wrote about the importance and joy of design practice. In that post I suggested that everytime we design something, we are practicing and improving our design skills. And while we do learn from our successful designs, we no doubt learn more from the failures that sometimes litter the path to a project success. If you have done any design practice at all, you have no doubt had a design … Read More

Big Engineering

Posted by Mike Jensen

Mike Jensen Most of the customers I work with design small systems, or smaller pieces of larger systems. Occasionally I get to see an end product: a car, an airplane, a mockup of the International Space Station to name a few. Most of these systems are built or assembled in one location, then put to work in another. In other words, the systems most of my customers work with are portable in a very general sense. On … Read More

SystemVision Model Wizard

Posted by Mike Jensen

Mike Jensen I wrote a month or so ago about the challenge of finding — or creating — simulation models. In that post, I suggested there are three general categories of engineers looking for a model: Give me a model Help me understand the model Help me develop a model For the “help me develop a model” category, I mentioned Graphical Modeling and Language-based Modeling as two popular model … Read More

Modeling: An Engineer's Dilemma

Posted by Mike Jensen

Mike Jensen Many of my recent interactions with customers have been on a single theme: modeling. Simulation is a great tool, but only if you have models that tell the simulator what to do. Models vary in type and complexity, but they all share a common purpose: to tell you something about how a device or system works, often in a specific application or under specific operating conditions. But there is a gap, an … Read More

What is Your Legacy?

Posted by Mike Jensen

Mike Jensen It happens every year in the fall: my birthday rolls around and I turn another year older. For good or bad, I am well into the time of my life where I have fewer years ahead of me than I do behind. I am not trying to be morose, just stating a fact. The numbers do not lie. And I suppose I am not unusual in occasionally looking back on my life wondering what my legacy will be. What will I be remembered … Read More

Simple Design Solutions

Posted by Mike Jensen

Mike Jensen I recently spent some time at a big-box store, an international retailer specializing in home furnishings and décor. Not the type of store where I usually spend a lot of my shopping time, but friends and family rave about it, so I decided to make a quick visit to see what all the fuss is about. Aisles in this store are somewhat narrow and have a lot of twists and turns. They wander so much in and out … Read More

Mike Jensen It is official: SystemVision 5.10 is finished and available for download from SupportNet. Even though this release took a bit longer than normal to complete, I believe the wait is worth it. Key among the new features are the following: Schematic symbol toolbar: Prior to SystemVision 5.10, placing symbols in a schematic required opening either SystemVision’s Search/Place Symbols dialog or DxDataBook … Read More

Engineering Muscle Memory

Posted by Mike Jensen

Mike Jensen I have written a time or two about my daughter’s piano recitals. As luck would have it, springtime is yet another popular recital season. This time my daughter had two – one for her own piano teacher’s studio, and the other as an invited duet accompanist to play in a friend’s recital. All-in-all, not a bad way to spend a mid-spring evening. As I listened to students play their prepared pieces, I noticed … Read More

EDA vs. Windows 8

Posted by Mike Jensen

Mike Jensen I have read a lot in recent months about Windows 8, Microsoft’s latest incarnation of its flagship Windows operating system. While there are many new features over and above its Windows 7 predecessor, one thing that makes me quite curious about Windows 8 is its optimization for touchscreen technology. Note that I have yet to use Windows 8, but I have used several other touchscreen devices on the market … Read More
