Finding the gate capacitance of an Inverter

[Prashanthanilm]

Hi all,

Can you please help me to Find out the gate capacitance of an Inverter?

I am working with cadence tool,

Thank you

with the report_timing, you could also report the -capacitance seen and other info.
Have you access to ETS (Encounter Timing System) which could read a Encounter SOC database, and have more report capacitance capability.
or look inside the .lib file.

RCA,

Considering I do have any access any file.

If I want to find the gate cap through simulations, how can it be done.

The tool will give the detail of pMOS and nMOS gate cap, but what about the total Inverter cap at once.

Please help me to understand this in more detail.

Thank you

serioulsy you have access to the file through the .conf file then you could access to the liberty.

The idea here is to know how to find through simulation.

Can you brief me about .conf file? Its content and relation with .lib

Thank you
