How to connect something to multiple inputs on different blocks?


Please consider the following block diagram (from here https://reference.digilentinc.com/vivado/getting-started-with-ipi/start?_ga=2.35038633.906437217.1554114007-924004044.1549634437 but with a utility vector logic block added):



I want push_buttons_5bits to remain connected to GPIO2, so I can read from them directly, like before.

However, I also want two bits, e.g. bit 0 and bit 1 from push_buttons_5bits to be connected to Op1 and Op2.

This has no purpose whatsoever, I'm just learning and would like to be able to read in my C code the result of the and gate.

Hi @aeon20,

I am not aware of an IP that demux the [0,4] output easily. I would think the easiest way to gain access to the first and second pin of the push_buttons_5bits  would be to write some VHDL/Verilog and demux signal 0 and signal 1 and then use the utility vector to use an and gate with the two signals.

best regards,
