Re: STA

SPEF file looks like this..
Cg552443 XAB/XR0/XSM/XQ1/XFGH/XCCT/XCCTL0/XCCTL/XPR/XP/XLFSRREG6/NET28 0 5.15396e-16
instance name followed by net and capacitance(lumped) of the net.
SPEF file has capacitnace of all the nets in the design. you have a control to choose different parasiticis like lumped capacitance, RC, CC. mostly lumped capacotance is used for the simulation because it will be faster.
 

Re: STA

SPEF (Standard Parasitic Exchange Format)
=========================================
IEEE 1481 Standard for Integrated Circuit (IC) Delay and Power Calculation System


SDF (Standard Delay Format)
===========================
IEEE 1497 Standard Delay Format
