Description
Summary:This paper presents timing models for RSFQ cells, based on conventional finite-state machines description. Models have been integrated, validated and verified in physical simulations and are suitable for VHDL design. A complete design flow from physical simulation to VHDL simulation, delays optimization, layouting and back-annotation is presented. The correctness of the timing models has been verified in an experiment with 4 /spl times/ 15 shift register.
