My project is to employ a DIP switch to select direction. When the push button is pressed counting up or counting down must be done depending on the direction of the switch and the count must be displayed on the zedboard. For this I have used a Counter(core generator). Although the simulation works properly there seems to be a constant zero on the LEDs of the board. We are using bus2ip_clk for our counter. Is it right or should some other clock signal be used.
