While the task of testing a single logic gate at a time sounds simple, there is an obstacle to overcome. For today's highly complex designs, most gates are deeply embedded whereas the test equipment is only connected to the primary Input/outputs (I/Os) and/or some physical test points. The embedded gates, hence, must be manipulated through ...

The main advantage of flying probe testing is the substantial cost of a bed-of-nails fixture, costing on the order of US $20,000, [3] is not required. The flying probes also allow easy modification of the test fixture when the PCBA design changes. FICT may be used on both bare or assembled PCB's. [4]
Digital design focuses on logical correctness, maximizing circuit density, and placing circuits so that clock and timing signals are routed efficiently. Analog IC design also has specializations in power IC design and RF IC design. Analog IC design is used in the design of op-amps, linear regulators, phase locked loops, oscillators and active ...
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
ATPG (acronym for both automatic test pattern generation and automatic test pattern generator) is an electronic design automation method or technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects.
Depending on the product, the machines that we are referring to could mean a combination of Automatic Test Equipment (ATE), handler, interface board, and test program that drives the ATE, as with the case of the IC chip testing. Test automation is a big part of a test engineer's job. The whole intention of automating the test is as follows:
