The Evolution of Test

First there were only hardware instruments. Then virtual instruments. Now, the test & measurement industry has evolved to embedded instruments, which are capable of validating, testing and debugging chips, circuit boards and systems from the inside out. Learn More


JTAG (IEEE 1149.x)

JTAG typically refers to technology that conforms to the IEEE 1149.x boundary-scan family of standards. JTAG comes from the Joint Test Action Committee which initiated development of the first boundary-scan standard (1149.1). The standard was designed for structural testing on circuit boards. Today, the JTAG acronym is often associated with the debug port on many processors, since this port usually conforms to the 1149.x standard. Learn More


On-Chip Debug

Many processor families include a set of debug features on-chip. When coupled to a toolset, these capabilities can be deployed in a number of board-level applications, such as board bring-up, device initialization, firmware development, at-speed functional and structural board test, and others. In essence, on-chip debugging capitalizes on the most powerful instrument available on most circuit boards. Learn More


I/O Instrumentation

Validating the signal integrity and performance of a circuit board’s serial buses with a probe-based instrument becomes much more difficult as the speed of the bus approaches 5 gigabits per second (Gbps). As a result, instruments are being embedded in chips to observe and provide empirical validation data at the on-chip receivers. Bit error rate testing (BERT), margining and other validation routines can be performed on I/O buses with these embedded instruments. Learn More


Intel® IBIST

Intel® Interconnect Built-In Self Test (IBIST) is a proprietary embedded instrumentation technology developed by Intel and placed in its leading chips and chipsets. IBIST is able to non-intrusively validate the signal integrity on high-speed buses and test these buses in volume production. Several other semiconductor companies have licensed IBIST and embedded it into their devices. Learn More


IJTAG (IEEE P1687 Internal JTAG) and other embedded instrumentation standards

Several embedded instrumentation standards have either been developed or are in the process of being ratified. The IEEE P1687 IJTAG standard specifies the interface to instruments embedded in chips so that any third-party tool conforming to the IJTAG standard will be able to manage and control these instruments. Other embedded instrumentation standards include the IEEE 1500 Embedded Core Test Standard and an addition to the JTAG family of standards, IEEE 1149.7. Learn More
