a problem for add module on FPGA

[chiyu.lin]

thanks for reading my problem

i have a problem on add lots of module on ISE,
while adding module in ISE, ISE should help you for hierarchy module
but i want to add lots of module(about 300), and ISE seems not recognize module hierarchy, so i think i may write the TCL for ISE instead of adding module manual.

can someone have example of TCL for add lots of module on ISE?

thanks a lot~
