01 Nov 1997TL;DR: A set of typical circuits described by netlists in HSPICE format is presented, which will allow engineers and researchers working in analog and mixed-signal testing to compare test results as is done in the digital domain.
Abstract: The IEEE Mixed-Signal Technical Activity Committee is developing a common set of benchmark circuits for use in researching and evaluating analog fault modeling, test generation, design-for-test, and built-in self-test methodologies. The first release circuits are based on MITEL Semiconductor's 1.5 /spl mu/m and 1.2 /spl mu/m CMOS technologies and they will allow engineers and researchers working in analog and mixed-signal testing to compare test results as is done in the digital domain. This paper presents a set of typical circuits described by netlists in HSPICE format. Schematic diagrams, simulation results and measured results, if available, are provided together with layout and a typical test environment. The full details are available on the web page dedicated to analog and mixed-signal benchmarks.

01 Nov 1997TL;DR: The challenges in testing core-based system-chips and their corresponding test solutions are discussed and the on-going standardization efforts are introduced, specifically under IEEE P1500 Working Group, which is meant to standardize the interface between a core test and its host the System-on-Chip.
Abstract: Chips comprising reusable cores, i.e. pre-designed Intellectual Property (IP) blocks, have become an important part of IC-based system design. Using embedded cores enables the design of high-complexity system-chips with densities as high as millions of gates on a single die. The increase in using pre-designed IP cores in system-chips adds to the complexity of test. To test system-chips adequately, test solutions need to be incorporated into individual cores and then the tests from individual cores need to be scheduled and assembled into a chip level test. However with the increased usage of cores from multiple and diverse sources, it is essential to create standard mechanisms to make core test plug-and-play possible. This paper discusses in general the challenges in testing core-based system-chips and describes their corresponding test solutions. It concentrates on the common test requirements and introduces the on-going standardization efforts, specifically under IEEE P1500 Working Group, which is meant to standardize the interface between a core test and its host the System-on-Chip.

13 Jun 2005TL;DR: The authors used a hardware implementation of the advanced encryption standard to show that the traditional scan DFT scheme can compromise the secret key, and showed that by using secure-scan DFT, neither thesecret key nor the testability of the AES implementation is compromised.
Abstract: Scan-based design-for-test (DFT) is a powerful testing scheme, but it can be used to retrieve the secrets stored in a crypto chip thus compromising its security. On one hand, sacrificing security for testability by using traditional scan-based DFT restricts its use in privacy sensitive applications. On the other hand, sacrificing testability for security by abandoning scan-based DFT hurts product quality. The security of a crypto chip comes from the small secret key stored in a few registers and the testability of a crypto chip comes from the data path and control path implementing the crypto algorithm. Based on this key observation, we propose a novel scan DFT architecture called secure scan that maintains the high test quality of traditional scan DFT without compromising the security. We used a hardware implementation of the advanced encryption standard (AES) to show that the traditional scan DFT scheme can compromise the secret key. We then showed that by using secure scan DFT, neither the secret key nor the testability of the AES implementation is compromised.

01 Nov 1998TL;DR: By appropriately connecting the inputs of all circuits under test during ATPG process such that the generated test patterns can be broadcast to all scan chains when actual testing is executed, it is shown that 177 and 280 test patterns are enough to detect all detectable faults in all 10 ISCas'85 combinational circuits and 10 largest ISCAS'89 sequential circuits.
Abstract: Single scan chain architectures suffer from long test application time, while multiple scan chain architectures require large pin overhead and are not supported by boundary scan. We present a novel method to allow a single input line to support multiple scan chains. By appropriately connecting the inputs of all circuits under test during ATPG process such that the generated test patterns can be broadcast to all scan chains when actual testing is executed, we show that 177 and 280 test patterns are enough to detect all detectable faults in all 10 ISCAS'85 combinational circuits and 10 largest ISCAS'89 sequential circuits, respectively.
