Making a monte carlo simulation component specific

simbamford
simbamford over 12 years ago
Does anyone know how to specify that for a monte carlo mismatch simulation (presumably using spectre though I also have an ultrasim license), one or two specific transistors will not be subject to mismatch, i.e. will give nominal performance, whilst every other component will be subject to mismatch? Of course it would be convenient if this were possible through the virtuoso inferface, but any method would be useful.Any help gratefully received.

    Hi Simbamford,

    There is a transistor parameter mmcflag that is set to 1 when its parameters are to be statistically varied. If it is set to 0, its parameters will not vary. You can set this flag to 0 for those devices whose parameters you do not want to vary.
