The OpenPOWER ISA Compliance Definition defines the test suite requirements to demonstrate OpenPOWER ISA Profile compliance for POWER8 systems.


The input to this specification are the following specifications:

  1. OpenPOWER Specification: Power Instruction Set Architecture (ISA) – OpenPOWER Profile which describes the categories of the POWER ISA Version 2.07 B that are required in the OpenPOWER processor chip architecture.
  2. IBM Power ISA Version 2.07 B


The testing of a processor implementation’s compliance against the Power ISA – OpenPOWER Profile ensures that software shown to execute properly on one compliant processor implementation will execute properly on a different also compliant processor implementation. The testing is not intended to show that the processor implementation under test is robust under all possible operating conditions, inputs, or event time interactions. It is intend to show that the processor implementation under test implemented the ISA as specified and the ISA specification was interpreted by the processor developers as intended by the ISA specification author.


This document is a Standard Track, Work Group Specification work product owned by the Compliance Workgroup and handled in compliance with the requirements outlined in the OpenPOWER Foundation Work Group (WG) Process document.
