Connecting a button with an input of an custom IP in FPGA

Hi all,

I created an custom IP in vivado. I need to give a logic 1 as an input to this IP via a push button in zedboard. So I need to connect a button with the port which is connected to the input of my IP. In order to check if the button is working I connected an ILA analyzer prob on the port too.

Q1: I run the implementation and everything went well. But when I presed the button nothing was shown in the ILA probe! What might be wrong!?

Q2: I am not using the axi_gpio IP. I am just connecting the port with the button in the constraint file by set_property command. SHould I use any IP between the port and my custom IP!?

Regards,
Jet.

There is an example of connecting to a push button on the ZedBoard in the Zedboard Zynq Concepts, Tools and Techniques tutorial in Chapter 3. Just connect to your IO instead of the GPIO using the same process.
The ZedBoard CTT tutorial can be downloaded here: http://zedboard.org/support/design/1521/11

Implementing the CCT exercise would validate the operation of the push button as well.
