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. Web3. The asynchronous reset can lead to metastability issues. To understand the metastability issue consider that the clock rising edge comes right after the reset edge. The D flip Flop must have certain minimum time between reset edge and clock edge, called reset recovery time. If this time duration is violated, the output is not guaranteed. michael checknoff
