Functional Pattern Generation for Asynchronous Designs in a Test Processor Environment
Found in: 2012 21st Asian Test Symposium (ATS)
By Steffen Zeidler,Christoph Wolf,Milo Krstic,Rolf Kraemer
Issue Date:November 2012
pp. 296-301
Testing asynchronous circuits has been a challenge for several years. Especially, the nondeterministic timing behavior leads to problems during test, since the occurrence of test responses is not aligned to tester cycles. For this reason a test processor s...
Overview on ATE Test and Debugging Methods for Asynchronous Circuits
Found in: Microprocessor Test and Verification, International Workshop on
By Christoph Wolf,Steffen Zeidler,MiloŇ° Krstic,Rolf Kraemer
Issue Date:December 2011
pp. 16-21
Due to mature design tools and proven flows for design and test the majority of today's circuits are synchronous. Increasingly complex designs pose major problems though with respect to clock tree design, interfaces running at different frequencies, peak c...
Design of a Test Processor for Asynchronous Chip Test
Found in: Asian Test Symposium
By Steffen Zeidler,Christoph Wolf,MiloŇ° Krstic,Frank Vater,Rolf Kraemer
Issue Date:November 2011
pp. 244-250
Due to asynchronous timing and arbitration asynchronous designs may behave no deterministically. For the test of such systems, this means that an exact timing, i.e. a tester cycle, of a test response cannot be guaranteed. This behavior makes functional tes...
On-line testing of bundled-data asynchronous handshake protocols
Found in: On-Line Testing Symposium, IEEE International
By Steffen Zeidler, Alexander Bystrov, Milos Krstica, Rolf Kraemer
Issue Date:July 2010
pp. 261-267
Asynchronous interfaces, being a popular way of dealing with timing closure problems in deep submicron SoCs, pose a serious problem for on-line testing. Their behavior is specified not as a traditional clocked automaton, but as an asynchronous protocol wit...
Ultra low cost asynchronous handshake checker
Found in: On-Line Testing Symposium, IEEE International
By Steffen Zeidler, Marcus Ehrig, Milos Krstic, Michael Augustin, Christoph Wolf, Rolf Kraemer
Issue Date:June 2009
pp. 262-268
This paper presents a new on-line checking scheme for asynchronous handshake protocols. The proposed scheme requires very small chip area while maintaining high coverage for all considered faults which are briefly exposed. In addition to simple pass-fail i...
