I have not used it but synopsys documentation says it supports SSTA
PrimeTime VX
The PrimeTime VX solution extends the PrimeTime environment to analyze device and interconnect variations at 65-nm and below using statistical techniques. Variation-aware analysis with the PrimeTime VX solution delivers improved margin control, avoiding the over- and under-design of circuits. Design robustness is improved by pinpointing areas of the chip most susceptible to variations so that designers can reduce this sensitivity and improve the parametric yield of production chips. PrimeTime VX analyzes systematic or deterministic process variation (die-to-die) as well as random process variation (on-die) in a flexible environment with a large range of features that can easily be introduced into existing design flows. PrimeTime VX allows users to leverage their existing investment in their trusted PrimeTime STA tool infrastructure, flow and knowledge.
