Reducing Costs During Prototyping

April 15, 2015

In our last discussion, we talked about DFT, which plays a significant role in reducing costs in prototyping. There are a wide variety of reasons that prototyping is a significant expense in the development and production processes. A large part of the cost is the increasing complexity of designs, inclusion of more processors and FPGA’s, greatly reduced board real estate, and diminishing test access. With the cost of FPGA’s and processors rising as they too become more powerful, getting small batches of devices is expensive. If one of those devices is fried during prototype testing, the cost to prototype a new design escalates rapidly, especially if the cause of the failure isn’t quickly determined.

Design For Testability?

April 8, 2015

Design for Testability, often referred to as DFT, is a critical part of developing a new board. Here’s a link to a terrific class lecture from University of Maryland if you’re interested in seeing a well represented academic presentation of such an important topic.

How Boundary Scan/JTAG Helps You Improve Your Bottom Line

April 1, 2015

As electronics production becomes more complex, and more expensive, board designers and manufacturers require tools that are better suited to handling the complexities of new designs. If this sounds like the same story you’ve heard from JTAG test companies for the past 10 – 15 years, it’s because now, more than ever, Boundary Scan Test Software / JTAG test and programming solutions are the best (read: most economical, accurate, safe, reliable, repeatable, consistent, flexible), choice for the handling of modern electronics.

SVF and onTAP Boundary Scan

December 8, 2014

Why SVF? As boundary scan test was making its way to center stage for testing surface mounted devices, there was no agreed upon protocol to manage the hundreds of thousands of bits of IEEE 1149.1 test pattern information. Instead, many vendors had vendor specific protocols for managing the data. In the early 1990s, Texas Instruments […]

Just Draw It!

March 19, 2014

Have you seen Digi-Key’s new FREE online schematic and diagramming tool? It’s called Scheme-it and can be used in most browsers with no plugins required. This great little freebie tool has a library of electronic symbols, as well as an integrated Digi-Key component catalog. Better yet, there is a built-in BOM manager to keep track […]
