A good help is on the xilinx site.
xilinx.com --> Support --> Problem Solvers --> JTAG Problem Solvers
From there, look for relevant info.

Hi,
I am new to configurating multiple devices through JTAG. Does anyone
know if it is possible to configure multiple devices (Xilinx Spartan
FPGA and CPLD) in a daisy chain through JTAG. The problem I face is
that the the devices concerned have different Vcc(s). The former is 5V
and the latter is a 3.3V device. Is it only possible to configure them
separately through JTAG. Thank you.
