most of the time the schematic portions which warrant accurate simulations can be reduced and modelled before running any simulation. For example reduce differential to single ended stages . Due to lack of accurate detailed models for specific parts, I just use generic models most of the time and tweak them for the main limitations the actual part might have in the given application . I usually simulate in spice just single stages . For larger systems , I go for a system simulator , like SystemView from Elanix . It's really nearly impossible to accurately simulate large complex designs in spice alone if you're not designing an IC and don't have the process parameters .
