Meet Satya

Satya is our VisSim Application Engineer in India. As he completes his second year with VSI, it is clear his command of VisSim for Model Based Embedded Development (MBED) has grown fast. He has become quite adept in VisSim use in motor drive and digital power applications. Satya has gotten great demand for his knowlege and training skills at a number of universites in India and has been teaching one and two-day seminars quite a bit this past year. He taught a two day course at the National Institute of Technology in Warangal last October. Attendance was strong and interest was keen among the attendees. Satya provides up to 40 TI Dev kits and students use VisSim to create various embedded programs during the course. Topics include PWM signal creation, ADC sampling, comparator usage, Trip Zone creation to shut down power on a variety if input conditions for safety concerns, I2C, SPI and interrupt handling round out his course. Course reviews are uniformly positive, with the once exception that two days is not quite enough time to cover all the material. If there are any professors out there who want to work with Satya to create a full semester course using MBED techniques, Satya and VSI are eager to work with you.

We asked Satya what drew him to VisSim. This is his reply:
"My career started as an Application Engineer working on small programs on LPC 2294 Microcontroller. Writing code, compiling, linking and debugging C and assembler code was quite cumbersome. The most difficult part was to understand behavior of a device driver. When I moved on to Model based Design I was amazed. You only keep the algorithm in mind without worrying about syntax or writing device drivers. In the semiconductor industry most of the embedded evaluation boards (ARM, Freescale, Philips) come with an external JTAG device, I have seen only Texas Instruments kits with a in-built JTAG debugger. And if you have a TI chip, then VisSim is for you. That's when I decided I wanted to work for the folks that make VisSim."

We asked him what else surprised him about VisSim: "Just the sheer speed of the code generation. I used to take hours to figure out how to program an embedded target, but in VisSim it happens in less than a second."

When asked what markets are a good application for VisSim, Satya replied: "I see an increasing demand for renewable energy and efficient digital power applications in India. I want to explain that TI has really focused on this market with their C2000 chip line. They have put a lot of technology into a single low cost chip dedicated to power applications. And of course VisSim/Embedded Controls Developer coupled with and Digital Power Designer make it easier than ever to program these chips for digital power applications. You do a system level simulation of your power stage and control to tune things up, then generating a real-time embedded control is automatic!"

You have done a lot of training this year. How have the students responded to your course?
"They have been very enthusiastic about the software and the material we covered. It's one thing to read about PWMs, or hear about them in a course, it's quite another to hold the board in your hands, configure a VisSim diagram that lets you modulate that PWM with a slider and see the PWM wave forms live in a digital scope on the PC. I really have enjoyed exposing people to this new way of developing embedded applications. It's clearly the way of the future and I am pleased that I can keep India on the forefront of this innovation."
