Whoa, That's a Big Piece of Equipment You've Got There

by Amelia Dalton

Fresh from the land of eye diagrams, super-fast SerDes, and more board design software than you'll ever need, it's Fish Fry! This week we investigate some of the biggest themes presented at this year's DesignCon in Santa Clara, CA. Our first guest is Rohde & Schwarz CEO Scott Bausback who joins Fish Fry to help us understand the ever-evolving world of test and measurement, explain how IOT will affect the evolution of T&M, and what it's like to build a recording studio in your house. Also this week, we chat with Stephanie Jarno from HUBER+SUHNER about how today's wicked-fast SerDes speeds are changing the demands on our cables and connectors.

 

Mimicking Touch

Leveraging the Biology of Tactile Sensation

by Bryon Moyer

Kids goof around with all kinds of things, not knowing what will occur. It’s how they learn how the world works, and it’s why they can learn novel electronic user interfaces so much more easily than adults (which we mistake as intuition). Well, in one such bout of goofing about on our apple orchard, I was monkeying with balloons over the opening of a bottle of apple cider.

You see, my dad had this thing where he’d poke a few needle holes in a balloon and then place it over the bottle opening. Fermentation would start, inflating the balloon, which opened the little holes and let the CO2 escape. When the process completed, the balloon deflated and the holes closed, blocking oxygen from reaching the inside – and preventing a continuation of the process that would otherwise lead to vinegar.*

Debugging Software Now Works Remotely

by Jim Turley

“Programming will be the last job on the planet.” – Jaan Tallinn, co-creator of Skype and Kazaa

Even hardware is software these days. With a hardware-development language (HDL), you can “compile” gates, boards, and even entire systems. Not everybody does… but you could. Software determines product functionality at least as much as the hardware does, and programming is a much easier skill to learn (and to teach) than hardware engineering. We’re becoming an industry of coders.

Yet one of the big downsides to programming is that you generally spend more time debugging your code than you do creating it. That’s the consistent conclusion of repeated surveys of professional programmers from around the world: they spend more time debugging than on any other part of the job.

 

MathWorks Targets Hardware/Software

Prototyping MATLAB and Simulink Algorithms on Xilinx Zynq and Altera SoCs

by Eric Cigan, FPGA/SoC Technical Marketing, MathWorks

The year 2011 saw a signature development in the FPGA industry – the introduction of two new programmable SoC devices. Xilinx introduced the Zynq-7000 All Programmable SoCs, and Altera introduced the Cyclone V SoC and Arria V SoC FPGAs. These new programmable SoCs, each packing a high-performance dual-core ARM Cortex-A9 MPcore along with ample amounts of programmable logic, offered advantages for a plethora of applications. Now designers could enjoy the benefits of software application development on one of the industry’s most popular processors while gaining the flexibility and throughput potential from hardware acceleration on a high-speed, programmable logic fabric.

 

DIY Clocks

Keeping Control Over Oscillation, Compensation

by Bryon Moyer

I should probably start with a confession. Clocks and oscillators have never been my strong suit. I get the concept of oscillation and I get the fundamental function of a crystal or other resonator, but there have been some aspects that have always bugged me – and yet I never had occasion to wrestle with them. Until now.

We’ll come back to the specifics of this in a moment, but I start with this comment simply to note (or perhaps warn) that I approach this topic with some level of naïveté. The benefit of that is that I may end up questioning things that don’t usually get questioned; the downside is that I may end up looking stupid. Of course, I risk the latter with every question I ask, so I’m somewhat inured to that possible outcome.

 

Buggy Bingo

Undo Software’s Live Recorder Makes Production Bugs A Thing of the Past

by Amelia Dalton

Needle in the haystack got you down? Got them buggy software blues slowin' your stride? Never fear, Fish Fry is here with a podcastin' elixir to blow those blues (and bugs) away. In this week's episode, we tackle production software bugs with Undo Software CEO Greg Law. Greg is here to unveil the new bug-busting capabilities of Undo Software's production bug insecticide: Live Recorder. Also this week, we check out why the Palo Alto Starbucks may not be the best spot for a super-secret meeting about your new IOT prototype. Finally, we see how The MathWorks is taking the maker movement to a whole new level - with math.
