UCR IE-0424

This repository is the starting code for the laboratories of the course IE-0424 (Digital Circuits Laboratory I) from the University of Costa Rica.

The course makes use of the following elements:

• picorv32: A small implementation of a RISC-V CPU.
• The Nexys 4 DDR board.
  • This board is now replaced by the Nexys A7.
  • This is a board with a Xilinx Artix-7 FPGA.
• Vagrant using Docker as provider for firmware compilation.
• In this project vagrant is set up to create a container with the required 32 bit RISC-V toolchain.

picorv32

This project uses a small implementation of a RISC-V CPU called picorv32.

This implementation from Claire Wolf is present as a Git subtree in the src/picorv32 folder of this project.

Scripts usage

This scripts allows to create a Vivado project from scratch.

cd tools/scripts

# Creates project and allows to run sysnthesis, implementation and bitsteam generation.
./create_project.sh -ic -ir

# Programs device (should be connected to the PC and turned on)
# The bitstream must have been created previously.
./create_project.sh -ip

# Opens Vivado (assumes vivado is in the PATH)
