Once upon a time, circa mid-1980's, surface mount technology (SMT) was becoming all the rage and it was widely reported that in-circuit test (ICT) was doomed! But lo, ICT had (at least) nine lives and would not die - the purveyors of "heavy metal" kept (keep) coming up with new innovations to keep the heart of the beast ticking…

The IEEE 1687 standard resonates with engineers and managers, no matter which part of the semiconductor-based product lifecycle they are involved with, because it either solves a technical problem, it provides a cost advantage, it reduces the amount of work, or it enables automation of some (onerous) task…

No Trouble Found?

In my earlier blog on Debugging Watchdog Timeouts I mentioned the dreaded No Trouble Found (NTF) problem. NTF is a huge cost to companies and is extremely difficult to quantify and to address. Something as simple as an errant wedding ring can cost companies millions of dollars. Let me explain…

For those working with the new Intel® QuickPath Interconnect (QPI) high speed bus, there's a new book on the market called “Mastering High Performance Multiprocessor Signaling” by Dave Coleman and Michael Mirmak. This will become the "Bible" on high speed buses. Here are the details...

This is the first of a series of blogs answering the question, “what is IEEE 1687”. Subsequent blogs will cover the topics “who uses IEEE 1687”, “what are the advantages of using IEEE 1687 (why use IEEE 1687)”, and “how to use IEEE 1687.”

Watchdog timeouts occur in crashed or hung systems when the main processor no longer sends a heartbeat to an ancillary service processor. These can occur in high- and low-end systems, anywhere from routers to servers to cell phones. Debugging them can be difficult…

Last week iNEMI (the International Electronics Manufacturing Initiative) concluded its nine-month project investigating Built-In Self-Test (BIST). The purpose of the iNEMI Project was to develop and promote the adoption of chip BIST at the board and system level. Here's a summary of the conclusions...

Why do I have to validate my board design?

Why do recent board designs need to be validated? Over the past few years we have seen a significant increase in signal speeds. In one generation of IA based boards, there was a 16x speed increase! This requires a new approach from designers and signal integrity engineers...
