WebJan 5, 2016 · Don't overlook the inverter on the D input of the FF. If S is low, then the FF itself is asynchronously reset, but due the negation of the Q output afterwars, it behaves as an asynchronous set of output Q of your entity Q1. If S is high, the FF stores the negated input at the rising clock-edge, which is again negated at the output. WebAug 13, 2024 · Even if you don't reset 2FF-synchroniser, you can still make it work. When such a 2FF-synchroniser is initially power-on and clocked, it drives an unknown value at its output for 2 clock cycles at most. In the next clock cycle, output will be driven to the actual value as at the valid input. If you make sure that the rest of the design in the ...
