It isn’t unusual to be doing this kind of logic design on FPGAs. There are several ways this can work. First, there are FPGAs that automatically include TMR flip flops that are very expensive.

If your combinatorial logic feeding the flip flop has a 9ns ... In the end, there’s no substitute for good design. Flip flops are a powerful tool for a digital designer’s arsenal.

It costs about as much as a conventional flip flop—counting component cost, assembly cost and logic design. But, Dr Noyce adds, in production quantities the cost of Micrologic elements will fall ...

This design idea (Figure 1) pushes maximum accurate operating frequency beyond 1 MHz by utilizing high-speed H-CMOS logic devices as extremely fast analog switches. D-type flip-flop #1 (FF#1) in the ...

Capacitor C1 then charges towards ground leaving the flip-flop with the Q output high ... the then newly available available CMOS logic from Motorola and Nat-Semi, career changes to Mainframe ...
