This respository aims to have a minimal redpitaya project under Vivado.

Create a new project with Red Pitaya constraints

Proceed as follow:

• Change "source.txt" to match your vivado installation and project directory.
• Open Vivado
• Use the TCL command line
• Copy the lines in "source.txt" to initialize Vivado and set the working directory
• Copy the lines in "project_template.tcl":
  • Either one by one, reading the comments to ensure you understand each part of the procedure.
  • Or in bulk directly in the TCL command line by typing "source project_template.tcl".

Explanations

The file "project_template.tcl" contains the minimal tcl commands to create a working Red Pitaya project. This project will do nothing but it will generate a bit stream, which is a good start for anyone getting started with Vivado and Red Pitaya.

The script does the following:

• Creates a new project based on the red pitaya hardware (Zynq-7 : xc7z010clg400-1)
• Creates a subfolder "tmp" to store all the files generated automatically.
• Loads the Red Pitaya ports and add them to the Block Design (file "config/init_ports_setup.tcl") (- Loads any custom ip that one may have built in "tmp/custom_ip ", if the lines are uncommented)
• Adds the Zynq-7 processing system block
• Adds the SATA buffer blocks
• Wires the clock and the SATA buffers to ensure that the constraints are satisfied later
• Generates all the files required for synthesis and implementation (- Loads any additional Verilog files in the folder "additional_v_sources", if the lines are uncommented)
• Loads the Red Pitaya constraints (files "config/clocks.xdc" and "config/ports.xdc")
• Sets up the synthesis and implementation runs (synth_1 and impl_1)
• Starts the synthesis, implementation, and bit stream generation

Continue

The bit stream will be generated in the implementation subfolder (tmp\my_project\my_project.runs\impl_1). The file is "system_wrapper.bit" You can copy it to your Red Pitaya root folder and launch it using the usual command: "cat /opt/redpitaya/fpga/fpga_0.94.bit > /dev/xdevcfg"
