Re: change frequency for ARTIX 7 from 100 to 250 Mhz, on ZYNQ-7020 ( ZedBoard )

g,

 

What is the problem?  On a Zedboard, there is the Zynq device, and not an Artix-7 device.  That Zynq device does use the same FPGA fabric as an Artix device, but all 7 series devices have the same FPGA architecture.

 

The Zynq device has the processor sytem, and the programmable logic section.

 

The HP ports run at 200 MHz, maximum (if I recall) on this board.

 

There are larger Zynq devices which may run their HP ports at 250 MHz (but that device is not on the Zedboard,
