Switching power

hi
I have designed 64 bit prefix adder. I used Leornado spectrum for sythesising my design but it only reports area and delay reports, no report for power .
How can i calculate switching power by calculating the switching activity in my design as in can i write a code to calculate that or is there any other way
Please reply
Thanx in advance

To compute the switching power, I think you need to know something about the capacitances that are charging or discharging, and I'm not sure that's available in a gate-level model.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.

Synposys' Synthesis tool gives some kind of power information. Its called DC analyzer ... I cant remember the name exactly....but it is one of the most popular tools used for synthesis in digital VLSI flow across many companies.
Sorry for very late and for very vague reply.

Design is fun, verification is a requirement.
