Colin Walls This is the first in an occasional series of postings with the title “Six of the Best”. This phrase is probably meaningless to many people outside of the UK and Australia and it is quite old fashioned here. It referred to the practice of punishing children with six lashes of a cane – a practice that is, hopefully, now consigned to history. However, I am not going to talk about corporal … Read More

Don Miller In this blog series I will cover the historical context which lead to the creation of Internal Flow Systems.  Covering both the motives and the methods behind the book and inevitably raises questions about the reliability of many of the other available sources of available data.  It will also make it clear that this isn’t a subject of academic interest alone; the subject of loss coefficients and system … Read More

Rich Rejmaniak It doesn’t matter if you’re reading this the day that it’s published, or decades later, there are some simple facts about computing devices that have held true since their inception.  A few years from now there will be processors available that far outstrip the current offerings in compute power and system complexity.  These processors will be cheaper than what you can get now.  Pretty much every … Read More

John McMillan “Most cattle are healthy most of the time; it’s the ones that aren’t that you need to know about.” We can never overstate the importance of cattle in our lives. Cows are not raised just for their meat, milk, and leather. The fact is, there are more products produced from cattle that are used in our everyday lives than many of us can fathom. Medical and pharmaceutical companies for example, use insulin … Read More

Colin Walls I have written before about multicore systems – here for example – and looked at AMP vs SMP and various other aspects of the technology. As the use of multicore designs has become increasingly mainstream, the options and possible configurations available has increased drastically. A particular facet is the incorporation of a hypervisor in an AMP system … All embedded systems have finite … Read More

Jamie Little Customers building applications for consumer products, medical devices, industrial automation, mil/aero, smart devices and so on have common concerns around managing data. Many developers turn to the Common Internet File System (CIFS) protocol that lets programs make requests for files and services on remote computers on the Internet. Since CIFS uses the client/server programming model, the client … Read More

Nazita Saye In my job I need to exercise a fair bit of creativity. Sometimes my ideas are readily picked up. Some require a lot of massaging and some never see the light of day… I used to take criticism of my ideas personally but not since hanging out with engineers. If there’s one thing I’ve learned from you guys is that there’s no such thing as failure – only outcomes. As Thomas Edison famously said “I … Read More

John McMillan The foundation of every PCB design is its libraries. And we all know that PCB designers and Librarians can spend a significant amount of time developing  the logic and footprint symbols required for each design. Well, here at Mentor Graphics we feel your pain. In fact, we’ve made a significant investment in PADS libraries that gives you, our users, immediate access to a new proven, pre-built, … Read More

Matthew Ballance Verification engineers spend lots of time creating tests. In fact, creating enough tests to verify the design functionality consistently tops the list of verification challenges, according to periodic surveys of our customers. Top Verification Challenges One challenge in test creation is that verification occurs in multiple environments. For high-level models, verification might be performed in a SystemC … Read More

John Day The Intelligent Transportation Society (ITS) World Congress in Detroit last week was quite an event, from Mary Barra’s keynote on Sunday evening, during which she announced GM’s entry into vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology, to Bill Ford’s Monday morning look at the future of transportation, to the myriad demos on Belle Isle, and the array of exhibits and panel sessions … Read More

Dennis Brophy From those just beginning to study electronic systems design to the practicing engineer, this is the time of the year when those taking their first steps to learn VHDL, Verilog/SystemVerilog join the academic “back to school” crowd and those who are using design & verification languages in practice are honing skills at industry events around the world. A new academic year has started and the Mentor … Read More

PADS VX Roundtable

Posted by Jim Martens

Jim Martens

Thanks to everyone for attending the PADS VX Roundtable webinar!  If you have not viewed it, it is now available on-demand Click Here To View Now!  We had great attendance.  I personally liked this new format – it gave Mike and me the opportunity to answer your questions directly, not just delivering a PowerPoint presentation. How did you like this new format? Is it something we should do again? Please

The Future of Integrity

Posted by Patrick Carrier

Patrick Carrier I have recently been blogging about signal and power integrity, how the two are related, and how they can cross over.  This was prompted by an article I recently wrote for the DesignCon branch of EDN.  Twenty years ago, one of the biggest barriers to designing high-speed PCBs was ensuring signal integrity.  About ten years ago, power integrity started becoming a serious issue.  So what is next?  Is … Read More

Patrick Carrier There are a lot of reasons to mix SI and PI analysis – trying to figure out a worst-case stimuli to determine PDN performance, trying to see the effect of a poor PDN on signals due to SSN issues, or just being able to properly analyze a single-ended via.  In fact, to get an accurate model of a single-ended via, you have to mix SI and PI.  The reason is that the power distribution network, or PDN … Read More
