In cadence simulation how to introduce noise in current source?

[nisha gupta]

In cadence simulation i am trying to simulate a comparator. and i am using ideal current source (or measurement case off chip or external current). Now i want to simulate this comparator with current source having some noise so that i can verify the measurement case (external current source might be having some noise).
Can any one suggest how can i introduce noise in current source for simulation. This comparator is very low power comparator. and external current is also very low (nA range)

Every current source from analogLib has noise parameters. Simply set them as you want.

Depends on the intended analysis type. Comparator simulation sounds like transient analysis, there's no simple way to include noise in transient analysis.
