Smelt is a simple and extensible task runner optimized for chip development workflows. Smelt makes it easy to programmatically define arbitrarily many test variants, run those tests in parallel, and analyze their results. Smelt provides simple and efficient workflows to both localized and distributed compute contexts.

Smelt is distributed as a python package and can be installed via:

pipx install pysmelt

Install smelt with pipx:

pipx install pysmelt

Create an smelt file, named tests.smelt.yaml -- below is an example

# tests.smelt.yaml
- name: test_example_1
  rule: raw_bash
  rule_args:
    cmds:
      # replace 'cmds' with whatever bash commands you want
      - echo "test1"

- name: test_example_2
  rule: raw_bash
  rule_args:
    cmds:
      - echo "test2"

- name: test_example_3
  rule: raw_bash
  rule_args:
    cmds:
      - echo "test3"

To execute all tests in a file, execute smelt execute tests.smelt.yaml
