Help me solve a clock skew and clock rate equation

my friend gave me a complex equation relating clock skew and clock rate.... it goes like this
Tclk ≥ Tsetup + Tcombinational + Tslew...

I've been trying to resolve and find how this equation resulted but without luck.... can someone help me.....

Re: clock skew

This equation signifies that "considering a digital circuit as a flip-flop followed by a combination logic followed by another flip-flop...... the clock period should be atleast equal to the clock-q delay of the first flip-flop plus the combinational delay plus the setup time of the second flip-flop..... suppose the clock arrives faster than this... the data at the second flip flop would not be valid.... becoz it wouldnt have propagated by the time and would have become valid"..............

Re: clock skew

Equation for set up and hold time

Here is the explanation for that equation..

first u want to know the meaning of T setup , T comb delay and T in-out..
T setup : The time for which the ip has to be before the clock transtion occurs.
T com Delay :the max time delay of the combination circuit in the circuit

T in -out: the time taken for the signal to propagate thr the flops i.e the time after which the i/p has the effect at the output...

Taking into these def, the clock time period should be atleast greater than r equal to the sum of above terms...

IF this condition is not met , the clock time period ll be less than the time taken for results to come out of the circuit


HOPE THIS ANSWER EXPLAINS U WELL..

ALL THE BEST.

To SHANS60,

When i download that file, its saying file is corrupted..
So can u pl post that file again..???
