Hey, I have a problem getting a clock signal. As you see in the picture did I create a fabric clock in the PL section and wired it to my own IP. Here is my Code for the IP: entity LEDSANIM is Port ( CLK_IN : in std_logic;
[Vivado 12-4739] create_clock:No valid object(s) found for '-objects [get_ports clk100Mhz]'. and later on: [Common 17-55] 'set_property' expects at least one object., in every I uncommented in the xdc. I don´t understand why this is an er...
