I need to establish the voltage point where a flop's clock input allows
the read of its D input.=20

There is some combinatorial logic in the same device. I was thinking
that it would be easier to measure the switching threshold on an "and"
gate.=20

The question is, if I measure the switching threshold on an "and" gate
will it be the same as the switching threshold on a flop's clk input?
both are in the same device and have the same technology.=20

(visualizing a flop as a circuit containing a bunch of nand gates, I'm
guessing it is the same, but I'm not sure.)

thanks.
