Abstract :
Currently, when a new fabrication process becomes available, all logic cells have to be re-designed, re-optimized and laid out from scratch. This is a manual and time intensive process, which hampers the migration of RSFQ circuits to better fabrication processes. The paper investigates the parameters that are required to specify logic gates that are technology and fabrication process independent. Ways of automating the optimization of the logic gates for implementation in new technologies, and automating the layout of logic cells for new design rules or new fabrication processes, are described. Cells can then be characterized for implementation in both LTS and HTS processes. Steps in the development of new logic gates and automation processes are shown.
