hello.I find this in my DC synthesis report: total area: 5962.365827
I've searched in this forum,and the number of total area is said to be equivalent with the gate count.
But why the numbers after "." are not zero?
I am using .35um lib through the synthesis.
the area unit depends on you lib,
in some lib, the area unit is transistors number,
but it is not absolutly, sometimes it is the are of transistors or other,
By the way, my DC synthesis report said the power of my chip which has a area of 30,000 gates ,is 2335 Watt.My tech lib is fujizu 0.25 um .Can any tell me what' s wrong with this. How can i modify my DC or lib setting to fix it.

really? I never heard DC can report power of chip. I think first of all you need to get the basic library information of your library, then try to figure out what happened. DC should have command to report these information, but i forget it.
it is a report about area, not gate number!
gate count = total area ( as in dc area report) / NAND gate area
our company also count according to this formula
