scan design

scan design

(electronics)
(Or "Scan-In, Scan-Out") A electronic circuit design technique which aims to increase the controllability and observability of a digital logic circuit by incorporating special "scan registers" into the circuit so that they form a scan path.

Some of the more common types of scan design include the multiplexed register designs and level-sensitive scan design (LSSD) used extensively by IBM. Boundary scan can be used alone or in combination with either of the above techniques.

Board designers and NPI test engineers are working together to implement boundary scan design for test (DfT).
In addition to the measurement capabilities, the sensor can be used to: promote rapid manufacturing and prototyping procedures; compare actual parts with CAD files; acquire data to manufacture and reconstruct tools and molds; scan data to generate milling paths; record data after tool release; scan design models for further CAD processing and documentation; and reverse engineer models.
Along with the two general talks (on thinking "out of the box" in error tolerance and error tolerance in razor processors) general topics include field analysis and modeling, scan design and test data compression, reconfiguration, error correcting codes and circuits, fault detection and tolerance for sensor and flash memory, delay fault test and timing considerations, defect and fault tolerant design in QCA circuits, interconnect test, approaches for soft errors, online and concurrent fault detection, fault and error tolerant systems, test scheduling and software-based test, and testing and design for analog circuits.
Most PCBA with good boundary scan design for test implementation will take care of the pull-up/down resistor of the JTAG pins to ensure stability of the boundary scan test.
One or more extra TAPs should be considered as additions to a boundary scan design for redundancy.
The high-capacity tool uses existing Verilog simulation libraries and provides comprehensive scan design rule checking, distributed processing runs across multiple processors, and yield diagnostics with automatic defect isolation.
The purchase options cover the properties with the Scan Design building on Willamette Street, three buildings on West Broadway owned by Eugene landlords Tom Connor and Don Woolley, including the empty Centre Court and adjacent pit, and a pair of buildings that house two bars, John Henry's and The Horsehead.

Before starting the boundary scan design, we consulted with the technical support group at JTAG Technologies to verify nothing would prevent us from running existing test-generation software for our proposed design, which combined 42 paddleboards and the midplane.
