Get started with vivado 24.1
DEVICE: ZYNQ7000 - AX7020
Create a project
Open vivado, and then click Create Project
.
Specify the project name and location. I use the breathing light circuit to demonstrate.
Select RTL Project
and check Do not specify sources at this time
.
Our device information is at Our device
To create the project, click Finish
.
Design
Now, it's time to add our verilog design source code.
First click Create File
, and then specify the File type
to SystemVerilog
and File name
to led
.
Here is led.sv
. You can paste it in.
Simulation
It's a good habit to write testbench for your verilog code. If you don't know how to write a testbench or you don't familiar with it, you should check the tutorials released by EDAPlayground, and here is the link.
Just name it testbench
.
Here is testbench.sv
. You can change the code as long as you fully understand it.
First click Run Simulation
, and then click Run Behavioral Simulation
to run simulation.
Here is the waveform.
Maybe you need to scale the waveform down. And you can drag dut (design under test) instance to the waveform to see the signals inside the instance.
Schematic
Click Open Elaborated Design
.
Click Schematic
, and then you can see an intuitive diagram showing up in the editor area.
Pin planning
In I/O Ports
window, set the Package Pin
and I/O Std
. The settings is related to our device details.
Click the upper left corner save icon to save the constrains. Just name it led
.
You can see led.xdc
created in your project.
Synthesis
Now run synthesis.
When synthesis completed, click Cancel
. Because we need to add timing constraints first.
Timing Constraints
Click Contraints Wizard
and then click Next
.
Set the timing constraints and then click Skip to Finish
.
Click Finish
.
You can see the timing constraints in led.xdc
automatically generated.
Generate Bitstream
Click Generate Bitstream
.
If you haven't run implementation before, vivado will give you a hint to run implementation and you just run it.
When bitstream generation completed, check Open Hardware Manager
and then click OK
.
Make sure our device is connected and power on.
Click Open target
and then click auto connect
. If the cable driver is correctly installed, you can see our device in the hardware window.
Possible solutions to "vivado cannot find your device" (linux version):
cd
to directory "/path/to/Xilinx/Vivado/<vivado-version>/data/xicom/cable_drivers/lin64/install_script/install_drivers
".
change "/path/to" to the real path to Xilinx for example "/tools" or "/opt"
change "<vivado-version>" to the real vivado version for example "2024.1"
In the directory, there is a
install_drivers
script (same name as the directory name), run using commandsudo ./install_drivers
UG973 may be useful to you.
Right click our device xc7z020_1
, and then click Program Device
.
Leave it the default Bitstream File and click Program
.
Now, you can see the breathing light effect.
