What is the coner simulation and how it works?

[wangse]

corner simulation + berkeley

I do not know exactly what coner simulation means.
How to set the resistor, cap, mos value in each case.
Please let me know about coner simulation

 

[ccw27]

.alter + corner simulations

Usually the spice file provided by the foundry contains this information. All you have to do is specify which corner (TT,SS,FF, ..) you want to run simulation.

Re: coner simulation

running corner simulation means running cases with variations in temperature, process parameters and voltage supply.

coner simulation

let the process all in the corner that make it fast/slow

coner simulation

On the other hand, u still simulate the schematic as the following:
resistors : change +/ 10%

coner simulation

It is different in the model select (TT FF FS SF SS).

 

[piao]

coner simulation

you can .alter change the corner when you run sim.

coner simulation

What are the corners, i.e., FF/SS/SF/FS, usually simulated along with the TT one? And how about Temp=?

If you have the lib set of hspice! you can do simulation.

 

[Luwengao]

coner simulation

If you use cadence analog environment, you can use ocean to run corner simulation

Re: coner simulation

The lib document provides you abundant information,so read carefully whenever you begin a simulation.
The attachment is an example from Berkeley...

Re: coner simulation

Your corner should include :
SS-FF-SF-FS for high-low temperature for high-low VDD, i.e. : 4x2x2=16 simulations!
If you include resistors Slow-Fast and capacitors Slow-Fast, you get 64 simulations ...

The guru of your company should setup trade-off to reduce them, otherwise ...
... use .alter command and wait for 1 night !!!
