CEVERO

The CEVERO comprises of a few forked repositories from the PULP Platform. This tutorial assumes you are using a version of Modelsim or Questa for simulation.

You must install the PULP gcc in your system. Download the release from pulp-riscv-gnu-toolchain and add the folder to your PATH enviroment variable, so that the binaries are accessible in the terminal.

Configuring Environment

Clone the following repositories

git clone https://github.com/cevero/pulpissimo
git clone https://github.com/cevero/pulp-sdk 
git clone https://github.com/cevero/pulp-rt-examples

Read the README.md from the repositories and install any dependencies that are needed.

Run the following comands to configure the repositories to compile the PULP Platform with the CEVERO core.

cd pulpissimo/
source setup/vsim.sh
cd ..
# sourcing the sourceme.sh might result in error if the SDK has not been compiled yet.
# if so, just ignore this error, and compile the SDK
source pulp-sdk/pkg/sdk/dev/sourceme.sh
source pulp-sdk/configs/cevero.sh
source pulp-sdk/configs/platform-rtl.sh

You’ll have to execute the comands above every time you restart your terminal and tries to compile the CEVERO. It’s advisable to copy the comands to a script for ease of execution. If you copy these commands to a file, config.sh, for example, you should source it.

source config.sh

Compiling Hardware

In order to compile the project, first compile the SDK.

cd pulp-sdk
make all

Then compile the SoC

cd pulpissimo
./update-ips
cd sim/
make clean lib build opt

Simulating Hardware

Then, to simulate, first source the config.sh file, in order to execute the source pkg/sdk/dev/sourceme.sh

source config.sh
cd pulp-rt-examples
cd error-recovery
make clean all run

To use the Graphic Interface of the simulator, use

make clean all run gui=1
