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...
 
Platform for automated HW/SW co-verification, testing and simulation of microprocessors
Found in: 2012 13th Latin American Test Workshop - LATW
By Aleksandar Simevski,Rolf Kraemer,Milos Krstic
Issue Date:April 2012
pp. 1-5
The high complexity of very deep-submicron Systems-on-Chip makes their verification extremely challenging task. Various methodologies based on traditional simulation, assertion-based verification, formal verification etc. help increase the confidence that ...
 
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...
 
Reducing the area overhead of TMR-systems by protecting specific signals
Found in: On-Line Testing Symposium, IEEE International
By Michael Augustin, Michael Gossel, Rolf Kraemer
Issue Date:July 2010
pp. 268-273
This paper presents a new method of fault-tolerant design for combinational circuits. For an arbitrary chosen subset X<inf>1</inf> of inputs the designed system is fault-tolerant, but not necessarily for the other inputs. For all the inputs fro...
 
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...
 
AWireless Communication Platform for Long-Term Health Monitoring
Found in: Pervasive Computing and Communications Workshops, IEEE International Conference on
By Daniel Dietterle, Jean-Pierre Ebert, Gerald Wagenknecht, Rolf Kraemer
Issue Date:March 2006
pp. 474-478
<p>Recent advances in wireless communication technology have opened the way for long-term health monitoring applications. In this paper, we introduce the BASUMA project, which will develop novel biomedical sensors and a wireless communication platfor...
 
Mapping of High-Level SDL Models to Efficient Implementations for TinyOS
Found in: Digital Systems Design, Euromicro Symposium on
By Daniel Dietterle, Jerzy Ryman, Kai Dombrowski, Rolf Kraemer
Issue Date:September 2004
pp. 402-406
Wireless sensor networks have attracted much research effort in the past five years. With TinyOS, there exists a widely used, microthreaded operating system targeted for single processor sensor nodes. It requires only minimal processing and memory resource...
 
Bluetooth Based Wireless Internet Applications for Indoor Hotspots: Experience of a Successful Experiment during CeBIT 2001
Found in: Local Computer Networks, Annual IEEE Conference on
By Rolf Kraemer
Issue Date:November 2001
pp. 518
Wireless Internet access based on wireless LAN or Bluetooth networks will become popular within the next years. New services will be offered that especially make use of location and personal profile to filter Internet access. Moreover
 
Self-organized Bluetooth scatternets for wireless sensor networks
Found in: Proceedings of the 11th ACM Conference on Embedded Networked Sensor Systems (SenSys '13)
By Mario Zessack, Stefan Lange, Steffen Peter, Michael Methfessel, Rolf Kraemer
Issue Date:November 2013
pp. 1-2
The wireless Bluetooth standard, generally used for short range point-to-point communication between mobile devices, can in principle connect any number of stations into a multi-hop network. For this purpose a "scatternet" must be built up, which is a coll...
