Flip-flop for use in LSSD gate arrays |
摘要 |
A flip-flop designed for use in gate arrays following LSSD design rules. The flip-flop has a data input D and a scan data input SD which are gated by control signals fmc, fmc' to the flip-flop input terminal 18. The flip-flop input 18 is gated into a master flip-flop consisting of two inverters 30, 32 coupled back-to-back by a gate signal DMC which is valid when the desired input signal is gated to the flip-flop input 18. The master flip-flop is coupled to a slave flip-flop which is gated by a different control signal. The slave flip-flop consists of two inverters 44, 46 coupled back-to-back. Inverters 48, 50 coupled to the slave flip-flop provide a buffered output therefrom.
