Create a file with a ".scs" suffix, and set up the distribution you want (see "spectre -h montecarlo" for more details.
Then reference this file with Setup->Model Libraries in ADE. In the ADE variables, define variable MYDC, and give it a value (this will be your mean value).
// statistics block for my
// design variables
vary MYDC dist=unif N=0.3
vary MYDC dist=gauss std=0.05
On an instance of the vsource, you can use the design variable "MYDC". If you want mismatch to be modelled, you'll need to ensure that the vsource is within a subckt - so create an additional level of hierarchy around the vsource in order to do this.
