This Episode #4 - An introduction to Triad's Sensor Processor Design Idea.

Welcome back everyone. Sorry for the delay in getting Episode #4 posted. I've been on the road quite abit and I've had some technical problems trying to record on the road. I'm looking to get those fixed (with Bert's help) so that even if I'm out visiting customers we can still get the podcast recorded and published.

!!!!! MAJOR ANNOUNCEMENT !!!!!

We are moving servers for the podcast and the blog for the next show.

If you subscribe to the show through iTunes, iPodder, or Odeo hopefully everything will get taken care of automatically but it you find out that by next weekend you podcast catcher software hasn't downloaded the latest show you may need to manually resubscribe to the show through those programs.

Our new podcast/blog server address where you can get our RSS podcast feed will be:

http://triadsemi.com/?feed=rss2&category_name=podcast

Sorry for this inconenience. We are switching over from Blogger to Wordpress because Wordpress integrated directly with our website, supports podcasting enclosures directly, and will allow us to get information out with better formatting in the future.

I will post a message to the old RSS feed location giving you audio directions on how to find the new show so if you get the "here's how to find the new show message" then you aren't pointing to the new feed. The Triad Alliance Newsletter for the week of Aug 15 will also contain directions for getting the new podcast feed setup.

Contest
Seems like a lot of you are having a good time with the decode contest so I'll keep it running for at least one more show. Refer to previous posts and podcasts to determine how to download the wave file and what you need to do to win a T-Shirt.

Congradulations to Ray Silva our latest contest winner.

TSX-SP Sensor Processor

The TSX-SP is a Design Idea. We haven't committed the design to silicon yet but all of the pieces for the Sensor Processor are in place within silicon. This one of the most exciting things about Triad's solution to me. As I talked about on Epsiode #3, our reusable analog and digital intellectual property (IP) allows us to quickly realize new mixed-signal products. The TSX-SP Sensor Processor is a very powerfull Sensor-to-Information computation unit. The analog front end (AFE) is the analog section from our in production TSX1 standard product combined with a complete microprocessor subsystem that we have integrated. I've always found it easy integrated new digital features into an FPGA flow. Now, you can do the same with analog and digital features together. After looking at the TSX-SP design idea you might say:

"hmmm....that's close...I like the idea but I wish it had 7 analog acquisition channels instead of 3"

Well, using the TSX-SP design as a starting point you could quickly and easily create schematics for a 7-input OpAmp section followed by a 7-1 analog mux and you'd have a 7-channel sensor interface design. By leveraging proven building blocks you can get started with software development using an FPGA for the microprocessor subsystem while your team designs the analog sections. We are literally talking days and weeks here - Not months and years.

FREE Reusable Analog IP

Triad MSSA analog circuits are designed out of our fine to medium-grained analog building blocks such as:
OTA (Operational Transconductance Amplifiers) Output Stages OpAmps (General Purpose, Low Power, Wideband) Resistors Capacitors Switches Individual Transistors
The functions are not designed at the GDSII (polygon) level -- we've already done that for you -- You design your circuit by interconnecting these elements at the schematic level and then spice and mixed-signal simulating the design.

Once your design pass simulation you now have a reusable piece of Analog IP.

On today's show we discuss an analog macro or analog IP block the:

Programmable Gain Instrumentation Amplfier or (PGIA)

The PGIA has 8 digitally controlled gain settings ranging from -6 dB to +30 dB. The gain is selected by a 3-bit digital word. This is a good first IP block to release and review because not only is it a usefull functional block but also because it isn't overly complex. If you look thru the PGIA Analog IP Documentation on the Triad website, I think that you will get a pretty good idea of what it takes to design a function using the Triad approach. The online documentation gives you an overview of the macro and shows how much of the MSSA's available resources are utilized to create the PGIA (not much). Other pages in the PGIA area show the schematics and Verilog code used to implement the PGIA. In a couple of days we will post the Mentor Design Architect schematics and spice models for the PGIA. I will let you know when that information is available.

Hello,
My name is Reid Wender. Here at Triad Semiconductor my title is "Manager - MSSA Design" but my friends just call me the Triad Evangelist.

What is MSSA Design you ask?

Mixed Signal Structured Array (MSSA) from Triad Semiconductor (site)

Triad Semiconductor makes the world's only Via-Programmable Mixed Signal Structured Array.

Okay, but I still want to know what a MSSA is?...

Okay, let me back up...

ASIC or A pplication S pecific I ntegrated C ircuit, semiconductor , IC , or just 'chip' are common names for miniature electronic designs placed on small pieces of Silicon. Well, I've been making these 'chips' for over 17 years and we have kept adding more and more transistors to these chips every year. In fact, there is a law (sort of) in our industry known as "Moore's Law", after Mr. Moore of course, that states that roughly every 18 months to 2 years you can put twice as many transistors in the same area of Silicon. This doubling of transistors per unit area is achieved by reducing the "feature size" of the transistors on the Silicon every 18 months or so. Back when I started digital ASIC design we were designing a 1.2 microns (micro meters) for features sizes. Over the past 20 years feature sizes have decreased (every 18 months or so remember) down to 1.0 micron, 0.7, 0.35, 0.25, 0.18, 0.13, and now 0.09 microns or 90 nano-meters as we like to say.

All this advance in technology and reduction in feature size is great for cramming more transistors and logic gates on to the same sized piece of Silicon.

Let me digress for a second - This is why electronics products keep getting cheaper over time. Every couple of years Intel and others are able to put out computer chips that are twice as fast and less expensive than previous generations.

Back to our story...

Feature size reduction is great for packing transistors onto Silicon but the downside is that as the feature size of the transistors get smaller the process required to make the ICs gets more and more expensive. In the old days you could get a 1.0 micron chip produced for $40,000 (we call it fab'ed - short for fabricated). Well todays 0.13 micron mask sets cost $800,000 (yep there is an extra zero in there).

Lots of companies have trouble forking over $800K to make a chip. Why does it cost $800K for a 0.13 micron fab versus $40K for a 1.0 micron fab. Well, a lot of the cost is in the "Mask Set " the mask set is a group of reticules that are used to expose the Silicon wafer to create the various layers of a semiconductor that make it act like transistors and logic gates. Many CMOS fabrication processes require 20 mask layers. As the features sizes get smaller and smaller the precision and time required to make each mask goes up.

Somebody, had the great idea that if you could reduce the number of masks required to make an ASIC you could reduce the fab cost. In fact, if you could make an ASIC with only ONE MASK LAYER you could reduce the cost by about a factor of 20. Instead of spending $800K on masks for a 0.13 micron chip you could then fab the chip for $40K.

Great idea but how do you do it?...

Now, I'll tell you about Structured Arrays
A structured array is a semiconductor with 19 of the 20 layers of the chip predefined with logic gates, memory, and routing. The one undefined layer or the layer that the customer defines is the via layer. This via layer allows vias (fancy name for a metal to metal connection in an ASIC - actually more complicated than that but this is a good definition for our discussions) to connect different transistors and logic gates to each other to form logic circuits. When it comes time to fabricate the chip the via layer mask is produced, and the chip fab'ed.

(more on structured arrays next time and we haven't even touched MSSA yet...)
