Title: Switching power
Post by akhil on Apr 14^th, 2010, 12:52am

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.

Than Geoffrey ...

Any synthesis tool which gives info on power ?

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.
