xilinx parallel cable iv power supply usb
this is my first programming CPLD.
i will use Xilinx XC9572XL-10. it is mounted on the PCB.
TDI TDO TMS TCK is okay.
but where should i connect the "Vref" wire?
what is Vref, is it target PCB's power ?
if Vref is target PCB's power voltage, does it mean we must download the CPLD, when the PCB's power is ON?
please help me.
