Xilinx ISE and included programs

When I look in to the Xilinx ISE I can saw many different programs. Like FPGA Editor, FPGA Floorplaner, XPower etc. Were can I find more info about what I can do with the previously programs?

Go to Help => Software Manuals=>Developement System Reference Guide

To summarise...

Architecture Wizard:
A quick point and click way to generate HDL for the DCMs and RocketIOs

Chip Viewer:
A version of FPGA Editor for CPLDs

Constraints Editor:
A helper for writing your UCF files

Core Generator:
A wizard interface for Xilinx (and 3rd party) IP

Floorplanner:
A tool that lets you assign HDL modules to specific areas of the FPGA

FPGA Editor:
A viewer/editor of the FPGA resources that are available and what has been used and how the nets are connected

iMPACT:
Configuration/programming tool (mostly for JTAG, but does other related stuff)

PACE:
Assign package pins with a drag/drop interface (also handy for viewing FPGA pinouts)

StateCAD:
A GUI state machine creator - outputs HDL

Timing Analyzer:
Static timing analysis tool

Webupdate:
Software updating via the Internet

XInfo System Checker:
Use this to get your system info if you're reporting a software bug

XPower:
Power analysis tool

Thanks for your help guys
