LibreCores Jenkins Pipeline Library

Table of Contents

This library contains common operations and logic for LibreCores CI.

Status

The library is under development. All commands may change, the compatibility is not guaranteed.

Classes

Modules

This is the class to more conveniently build CI based on Environment Modules (http://modules.sourceforge.net/). First modules are loaded to the environment and calling sh() then executes the command(s) in that environment.

Usage:

@Library('librecoresci') import org.librecores.ci.Modules
def lcci = new Modules(steps)

node('librecores-ci-modules') {
  lcci.load(["eda/verilator/3.902"])

  stage('Simulation Build') {
    lcci.sh 'verilator -f verilate.vc'
  }
}

Commands

sh_with_modules()

Executes the sh() command with initializing the specified modules before executing.

Example:

node('librecores-ci-modules') {
    sh_with_modules(modules: ["gcc", "fusesoc/1.6"], command: "make all")
}

Effectively the example above creates commands like source ${modulesPath}/init/bash && sh "module load gcc && module load fusesoc/1.6 && make all".

openriscPipeline

Builds a pipeline for OpenRISC projects.

Out of the box it configures: - Pulls Docker images for librecores-ci-openrisc - Executes jobs in parallel inside Docker images

Example

This snippet is from the Jenkins pipeline for mor1kx

@Library('librecoresci') _

openriscPipeline {
        job('verilator') {
            job 'verilator'
        }

        job('testing-1') {
            job 'or1k-tests'
            sim 'icarus'
            pipeline 'CAPPUCCINO'
            expectedFailures 'or1k-cy'
        }
}

fusesoc

Builds a step for a generic FuseSoC invocation.

  • Chooses a base docker image with FuseSoC

  • Adds library to FuseSoC

  • Runs FuseSoC step

  • Runs arbitrary shell commands in this step

Example

@Library('librecoresci') _

pipeline {
    stages {
        stage('example-fusesoc-step') {
            fusesoc {
                image 'librecores/librecores-ci:0.5.0'
                library 'some_core', '/src'

                run('some_core') {
                    target 'fusesoc_target'
                }

                shell "echo 'Additional steps on shell'"
            }
        }
    }
}

yosysSynthesisReport

Build a step for Yosys Synthesis for monitoring resource usage statistics and publish on Jenkins.

  • Generalised Yosys Synthesis

  • Can be configured for various hardware projects

  • Simple declarative call which requires parameters core, target, logpath

  • Can be modified and extend to include more paramaters in future.

Example

@Library('librecoresci') _

pipeline {
    agent any
    stages{
        stage('yosys') {
            steps {
                yosysSynthesisReport {
					core 'mor1kx'
					target 'synth'
					logPath 'build/mor1kx_5.0-r3/synth-icestorm/yosys.log'
				}
            }
        }
    }
}
