Tired of that old bed-of-nails? Legacy In-Circuit Test (ICT) has been diminishing in value for a long time. Let’s explore some of the current technical issues with ICT as test access on new circuit board designs continues to disappear.

ScanWorks Embedded Diagnostics is embedded firmware which uses a CPU’s debug port to access a system’s architecturally visible registers, memory and I/O. See the technology and benefits behind this "debugger on steroids".

ScanWorks Embedded Diagnostics for x86 systems requires a connection between the embedded service processor (BMC, FPGA or other) supporting run control and the target CPU(s). The nature of these connections is described herein.

As testing with legacy equipment becomes more problematic, engineers look for better ways to improve test coverage, enhance diagnostics, and speed up test times. But an overriding consideration is the cost of test – are the new test technologies more or less expensive than older solutions like ICT?

The test stack

Those of you with a telecom background are no doubt aware of the “OSI Network Model”, also known as the OSI pyramid or stack. It is a way of sub-dividing a communications system into smaller parts called layers. A layer is a collection of similar functions that provide services to the layer above it and receives services from the layer below it. A decade ago, the telecommunications test industry underwent a revolution when platforms emerged that could cover multiple layers of the OSI stack. Now, the same thing is happening in the circuit board test industry...

Testing 2nd generation Intel® Core™ microarchitecture (aka Sandy Bridge)

Some of you may have noticed Intel’s announcement this past week at CES of the new generation of desktop/mobile processors, the 2nd Generation Intel Core family. These processors are based upon a new microarchitecture at a 32nm process node. This increased level of density and functionality requires new board testing strategies...

Test coverage using multiple technologies

It is a well-known fact that manufacturing test strategies must involve a combination of inspection, structural, and functional test technologies in order to yield highest quality and minimize customer returns. But a new breed of non-intrusive, software-based technologies promises to disrupt legacy test solutions by guaranteeing the highest test coverage at the lowest cost. These technologies leverage off of the embedded instruments within silicon to achieve this goal in the following ways...

The world of validation has changed dramatically over the last few years due to the added challenge of increasing bus speeds. My observation across the industry is there are two camps companies are aligning on...

Structural versus Functional Test, and Test Coverage versus Diagnostics

What’s the difference between circuit board structural test and functional test? And how does test coverage relate to diagnostics? These terms are sometimes used interchangeably, but not knowing the difference may result in a less-than-optimal test methodology. Let me explain…
