This book contains papers first presented at the 4th International Workshop on Field- Programmable Logic and Applications (FPL'94), held in Prague, Czech Republic, September 7 - 9, 1994.

The FPL'94 workshop was organized by the Czech Technical University and the University of Kaiserslautern, in co-operation with IEEE Czechoslovakia Section and the University of Oxford (Dept. for Continuing Education), as a continuation of three already held workshops in Oxford (1991 and 1993) and in Vienna (1992).

This volume contains the proceedings of the 4th International Workshop on Field-Programmable Logic and Applications (FPL '94), held in Prague, Czech Republic in September 1994. The growing importance of field-programmable devices is substantiated by the remarkably high number of 116 submissions for FPL '94; from them, the revised versions of 40 full papers and 24 high-quality poster presentations were accepted for inclusion in this volume. Among the topics treated are: testing, layout, synthesis tools, compilation research and CAD, trade-offs and experience, innovations and smart applications, FPGA-based computer architectures, high-level design, prototyping and ASIC emulators, commercial devices, new tools, CCMs and HW/SW co-design, modelers, educational experience, and novel architectures.
