Base System Architecture (BSA) specification specifies a hardware system architecture based on the Arm 64-bit architecture. Server system software such as operating systems, hypervisors, and firmware rely on this. It addresses PE features and key aspects of system architecture.

BSA Architecture Compliance Suite (ACS) is a collection of self-checking, portable C-based tests. This suite includes a set of examples of the invariant behaviors that are provided by the BSA specification, so that implementers can verify if these behaviours have been interpreted correctly. The tests are executed in a baremetal environment. The initialization of the baremetal environment is specific to the environment and is out of scope of this document.
- Code Quality: REL v1.0.8
- The tests are written for version 1.0 (c) of the BSA specification.
- The compliance suite is not a substitute for design verification.
- To review the BSA ACS logs, Arm licensees can contact Arm directly through their partner managers.
Contact your EDA vendor and ask if they include these tests as part of their verificatoin IP package.
- To pick up the release version of the code, checkout the corresponding tag from the main branch.
- To get the latest version of the code with bug fixes and new features, use the main branch.
- For details on the BSA ACS test execution, see the Arm BSA ACS User Guide.
- For details on the Design of the BSA ACS, see the Arm BSA Validation Methodology Document. Note: The Baremetal PCIe enumeration code provided as part of the BSA ACS should be used and should not be replaced. This code is vital in analyzing of the test result.
Any 64-bit Arm based Server design presented as a full chip Emulation or Simulation environment
The baremetal build environment is platform specific. To provide a baseline, the build steps to integrate and run the tests from UEFI shell are provided here.
