regarding multimode multicorner

I'm having lot of doubts regarding MMMC.i know what are the corners and modes all.


I d't know how to implement MMMC. what are the files we need for this analysis.
how we have to idetify this much of corner ll be there in our design.
ple explain me.....

Same files as simple setup/hold mode, I means liberty, sdc
In MMMC, you define more views which could associated to setup and/ or hold time.

A mode is defined by a set of clocks, supply voltages, timing constraints, and libraries. It can also have annotation data, such as SDF or parasitics files. Many chip have multiple modes such as functional modes, test mode, sleep mode, and etc.
A corner is defined as a set of libraries characterized for process, voltage, and temperature variations.
Corners are not dependent on functional settings; they are meant to capture variations in the manufacturing process, along with expected variations in the voltage and temperature of the environment in which the chip will operate.

For this you requires libraries, SDC, SPEF for the different corners. This MMMC information is specified in SDC file. In Encounter this information is specified in viewDefination.tcl.

thank u sir
