I'm not entirely sure what you're asking here (it's a bit vague). In order to see 1/f noise, you need to have the appropriate parameters in your device models - exactly what those parameters are depends on the model type. Traditionally these were called af, ef, kf - but newer models have different parameters which can be used instead.
Apart from that it's a matter of doing a noise or sp analysis (or pnoise/psp, qpnoise/qpsp for periodic or quasi-periodic circuits) and looking at the results. Reading the manuals would probably help (Spectre user guide/reference guide and analog simulation help in cdsdoc).
Regards,
Andrew.
