Why D flip flop is widely used in ASIC?

There must be some reason....Can anybody post it here?


As opposed, may I ask, to what? JK flops? C gates? Maxwell's daemons? Specificity of question leads to specificity of answer.

Homework question?

Probably because they were widely used in discrete logic design for the 20 or 30 years before ASIC's

Probably because it uses the least amount of chip area of any of the candidates for storing a bit.

And _that's_ probably because it's close to a SRAM cell, so there's been intense work over many years in making it as small and cheap as possible.

Lumped element logic design is so last year...

Well, for some things my primary reason is hunger. For some others it may be tiredness. Then there is boredom. HTH.
