I am trying to do power analysis of a part of my design. I want to generate a .vcd file (which seems to contain the switching activity for all elements in the design) for giving as input to XPA. I can't seem to generate the vcd file because I am missing the "vcd" utility. I even tried the "saif" utility, it's not there as well. I am using Xilinx ISE 9.2i, is it possible to get these utilities standalone (I tried google it didn't work!)?

The standalone Xilinx Power Estimator (XPE) can be found here.
The more accurate XPower Analyser (XPA) is part of the ISE suite. You can download and install ISE 12.4 and still keep your ancient ISE version running on your machine.

VCD information or SAIF information comes from the HDL simulator you are targetting. If you look in the XPA help, there are instructions on how to enable this for simulator of choice.
In Project navigator, if you are using ISim, you can enable this in the properties for post-par simulation flow.
If you set the switch to write an SAIF file for power analysis and then run Power Analysis, it will be done for you.
