I started using Zedboard recently. I was using ISE 14.2, and I could generate the suggested flow including the LEDs connected to teh GPIOs through AXI lite, but I recently upgraded to the latest version 16.4 and when I create the HW platfrom in XPS I cannot find the Base system builder, wizard which appeared automatically in version 14.2. Without it I can't create an AXI project and I can't find how to connect the LEDs to the GPIOs. Anyone had this same problem?
