Create HW platform (XSA) in Vivado 2023.2

1. Run Vivado and create Vivado Project:

source /eda/scripts/setup_vivado.sh
PROJ_DIR=${HOME}/my_nas/lab_msw_ex6

• select Zybo Z7-20 board from Digilent

• add master Zybo constraints file SDF from Digilent (now it is totally commented out, but it can be useful when you later use the devices that are on Zybo board):

/eda/Xilinx/Vivado/2023.2/data/boards/board_files/Zybo-Z7-Master.xdc

2. Create block design:

• add ZYNQ7 Processing system

• Set master PL clock from 50 to 125MHz (required for Ethernet card): Clock Configuration/PL Fabric clocks/Set FCLK_CLK0

• add buttons, switches, LEDs, GPIOs etc.

• if not adding any AXI peripheral, remove M_AXI interface from processor to avoid errors regarding clock: PS-PL Configuration/AXI Non Secure Enablement/GP Master AXI Interface/M AXI GP0 interface = OFF

• check/add/correct SDC constraints, if needed

• add HDL wrapper:

• Sources window/right-click on block diagram/Create HDL Wrapper

3. Generate bitstream

4. Export XSA hardware:

• File/Export/Export HW (include bitstream) File/Export/Export Hardware… + Include bitsream

Your XSA file will be in the Vivado project root folder (i.e. vivado_prj/zybo-z7-20-hw-platform.xsa). Save the XSA file path and name for the next step!
