Does Xilinx ISE contain the IP core or primitive that can config FPGA by other CPLD or FPGA ?

Re: Does Xilinx ISE contain the IP core or primitive that can config FPGA by other CPLD or FPGA ?

The amount of bits you need to configure a small FPGA is generally speaking large compared to the dedicated RAM resource of a large FPGA, so I would be surprised if many people would decide to do such a thing.

Or are you thinking of daisy-chained configuration?

PC sends configuration data to an FPGA though PCIE interface IP core.

And if this FPGA receives this data, it sends these data to the other FPGA after an FIFO.

I use an FPGA to config the other FPGA, so there are two FPGAs.

I don't think that any built-in cores or primitives will do everything for you. You could implement a simple slave serial controller and configure other FPGAs with that, though.

see this link it will give clear primitive detils
