"Synthesis and TEsting of Low-Latency Asynchronous circuits" (STELLA)

funded by EPSRC (GR/S12036) 244,563 pounds.
GRANT REVIEW RESULT (23/10/2006) - Overall assessment: Tending to Outstanding In particular:

Duration: 1.01.2003 - 31.03.2006
Principal Investigator: Prof. Alex Yakovlev
Co-investigators: Dr. Alex Bystrov, Dr. Gordon Russell, Dr. Albert Koelmans and Prof. David Kinniment
Main Research Staff: Dr. Delong Shang, Dr. Agnes Madalinski, Dr. Danil Sokolov, Miss Deepali Koppad

The project aims to develop an overall performance-oriented architecture and design methodology for asynchronous, predominantly control, blocks which will focus on the aspect of minimisation of input/output delay. The project will provide a high-productivity design flow, based on circuit compilation, with circuit structures, libraries, algorithms and tools for synthesis, timing analysis and testing of self-timed circuits with low-latency. Methods for incorporating generic scan based circuitry and on-line testing with low speed penalty will be of particular interest. The project will investigate a series of case studies and produce a demonstrator VLSI circuit, e.g. a controller for on-chip communication, to prove the feasibility of the design technology supporting both productivity and performance. An additional important outcome of the project will be its contribution to the problems with resolving important tradeoffs in designing SoC as on-chip networks, particularly: predictability and determinism versus average performance, aggressiveness in speed versus testability and robustness.
