Chip-Level Tests

Overview

This subtree contains three types of chip-level tests that are capable of running across all OpenTitan verification targets, using the on-device test framework. These targets include: DV simulation, Verilator simulation, FPGA, and eventually silicon.

Test Types

  • Chip-level Tests - A collection of software level tests that run on OpenTitan hardware, whose main purpose is pre-silicon verification and post-silicon bringup. These tests consist of: smoke, IP integration, and system-level tests. While most of these tests are top-level agnostic, some are not.
    • Smoke Tests - A software level test, written in C using DIFs, that performs a minimal set of operations on a given IP block to verify that it is alive and functioning.
    • IP Integration Tests - A software level test, written in C, that exercises some specific functionality specific to a given IP and toplevel.
    • System-level Scenario Test - A software level test, written in C, that mimics complex system level use case scenarios. Such a test is designed to encompass multiple pieces of functionality tested by the IP integration tests.

Organization and Style Guide

File Naming Conventions

  • Smoke tests: {IP name}_smoketest.c
  • IP Integration tests: {IP name}[_{feature}]_test.c
  • System-level tests: {use case}_systemtest.c

Subfoldering Rules

  • Smoke tests will be placed in (one per IP):
    • (generic) sw/device/tests/
    • (earlgrey-specific) sw/device/tests/earlgrey/
    • ({toplevel}-specific) sw/device/tests/{toplevel}/
  • IP Integration tests will be placed in the same folders as above.
  • System-level tests will be placed in the same folders as above.
  • IP Integration Test data (some tests, e.g. OTBN, load data files): sw/device/tests/{IP}_data/
  • Target-specific tests will be subfoldered by target (see below).

Subfoldering Target-Specific Tests

Ideally all smoke, IP integration, and system-level tests should be target agnostic. However, some tests require emulation of host capabilities, such as an external SPI or I2C host, an external host to encrypt/decrypt data, or an external host that toggles GPIO pins. Eventually, host-side test initiation tools and the on-device test framework will make host emulation opaque to each chip-level test. However, until then, host emulation depends on the target (e.g., DV vs. Verilator simulation). Therefore, chip-level tests that require external stimulation from the host, will be subfoldered by target, under the appropriate toplevel folder above. One example of such a test is the sw/device/tests/sim_dv/gpio_test.c, which is subfoldered under ../sim_dv/ to indicate it is a target-specific test.

Writing a Chip-Level Test

For instructions on how to write a chip-level test, refer to the on-device test framework page.
