How to get SAIF file ?

You can also use simulators supporting Synopsys PLI interface for SAIF generation like NCverilog, VCS, ModelSim.

ur SAIF is prime source of generating dynamic power estimation for ASIC. Test stimulus must be proper for getting a near real power estimation. once simulation is done, dump the VCD file and convert VCD to SAIF using vcd2saif and input this to primepower along with netlist for getting the power estimation.

For static power analysis, SAIF is not a necessary input.
------------------------------------------------------------------------

Leakage power report depends on the library(.lib) used,
if the leakage power in the library is not state-dependent,
then no SAIF is needed.
-------------------------------------------------------------------------

However, if the value of cell leakage power is state-dependent
in the library, then the SAIF used for dynamic power analysis
can be also used for leakage power analysis.

AFAIK except VCS all other simulators that support the PLI interface need to be configured in terms of giving them an additional parameter which shows the path to PLI library file. For example for NCverilog on SUN platform you need to add the following command-line parameters when invoking NCverilog:

ncverilog +loadpli1=$SYNOPSYS/auxx/syn/power/vpower/lib-sparc64/libvpower.so:saifpli_bootstrap

where $SYNOPSYS is an env. variable containing path to your synopsys tools directory.
