what is race around condition

Answer Posted / sowmya

A fliplflop is a basic digital memory circuit.In JK
flipflop when the clock pulse is equal to 1 and also when
j=k=1 , we know that the next state is complement of the
present state.but at that instance if clock pulse is
still '1'(high)the o/p again complements.and it repeats
untill clk puls goes back to '0'.this is race aroud conditn.

This is because that clk puls duratn is more than the
propagatn delay of flipflop.to avoid this we need to adjust
the clk pulse duratn or we need to put restriction on clk
pulse width as
clk pls (t)<propgatn delay using mater slave configuratn
