I was wondering if anyone could help answer the following:

What does including a ".d" extension mean when defining logic equations into 
CUPL programming language? In the notes it says that adding this extension 
defines the output as a "flip-flop" output. Does this mean that the output 
only occurs on the rising edge of the clock?

If so, how does this make adding the ".d" extension much different from 
leaving it out (since the rising edge of the clock happens so many times per 
millisecond)? In other words, what would require making the outputs of the 
programmed state machine into "flip-flop" outputs compared to making them 
"regular" outputs.

Thanks,

Darren Hon
