How do I calculate the delay in the waveform

[sekartut]

I have been working in the ALU desigh using tanner EDA.
I didn't know how to calculate the delay, power delay product, etc..
Please help me in calculate this

hi.
1.delay between any two is usually calculated 50-50%value.
i.e let us say vin is i/p ,vout is the output vin&vout take value from 0v-5v.
then delay b/w vin & vout(vin as reerence) is time b/w vin=2.5v&vout=2.5v.this is called propagation delay.
but in general this is the trick.in tools also this is usually followed.
2.then powerdelay is the product of power consumed by the circuit & the propagation delay of the circuit.
pandit..

First you must find the rise time and the fall time of your waveform of your i/p & o/p. Then you subtract the o/p rise time to the i/p rise time or vise versa.
