One of the EDA Playground examples shows a D flip flop with an asynchronous reset you can experiment with. A T (or toggle) flip flop changes state on each clock pulse (at least, on each enabled ...

This paper proposes a configurable asynchronous set/reset flip-flop design that tends to resolve the timing and implementation issues concerned with such post-silicon metal ECOs and compares the ...

Synthesis programs in modern IC and FPGA designs ensure that digital circuits meet the setup-and-hold requirements for each flip-flop in the design; however, asynchronous signals pose problems for the ...

As shown in Figure 1 and Figure 2, flip flop A and B1 are operating in asynchronous clock domain. There is probability that while sampling the input B1-d by flip flop B1 in CLK_B clock domain, output ...
