PREFACE
The material included in this document is based on all the work on
this unique ultrafast digital technology, which has been carried out
since its introduction in 1985, but the collection itself was compiled
only in early 1999, within the framework of the JPL-led HTMT petaflops
project. As a result of a federally-funded project, this document
is in the public domain and is open for free use, with appropriate
references in all resulting publications.
Before you start browsing the library, two words of warning:
- Though most circuits in the library have been experimentally
verified, and many of them optimized for
interconnectivity, generally RSFQ circuits should be
re-optimized for best performance (e.g., using one of existing
optimization tools) after they have been composed from
library components. In this context, our group may not be held
responsible for the possible poor performance of a circuit
formally assembled from our library.
- The layouts shown in the library have been designed for the
standard 1 kA/cm2,
3.5 um niobium-trilayer process of HYPRES, Inc. With due respect to
the outstanding role of this technology for the development of
RSFQ throughout the 1990s, most prospective RSFQ applications
(including petaflops-scale computing) require more advanced
fabrication. For these prospective technologies, our layouts
should only be used as hints.
With these reservations, go ahead! We will be glad to hear your
comments. They should be sent to either the authors of individual
component descriptions (listed below) or to K.
Likharev.
