vivado vitis ide

 

import pynq-z1 to vivado, create new project

add processor, leds, buttons

auto connect, rename leds (rgb), buttons (btns)

create HDL wrapper

add constraints file, check copy constraints file to project

//uncomment buttons and leds in constraint file, match name with diagram

##Buttons

set_property -dict { PACKAGE_PIN D19   IOSTANDARD LVCMOS33 } [get_ports { btns[0] }]; #IO_L4P_T0_35 Sch=btn[0]

set_property -dict { PACKAGE_PIN D20   IOSTANDARD LVCMOS33 } [get_ports { btns[1] }]; #IO_L4N_T0_35 Sch=btn[1]

set_property -dict { PACKAGE_PIN L19   IOSTANDARD LVCMOS33 } [get_ports { btns[3] }]; #IO_L9P_T1_DQS_AD3P_35 Sch=btn[3]

##Switches
