I am facing problem in adding noise in transient analysis in cadence spectre .
Can help me how to add noise as input source for transient analysis using simulator cadence spectre .
You're using too old a version of spectre. You're using a bang up to date version of the IC tools, but are 3 major releases back on the simulator... there have been MMSIM10.1, MMSIM11.1 and MMSIM12.1 in the meantime. I suggest you move to the latest MMSIM12.1 hotfix.
With this, you can do what you want.
