Statement of Work (SOW)

Component names:
RV32/64I

Requirements:
Generate tests for hint ops to confirm that they have no architectural observable effects.
This would setup registers and initialize CSRs, execute the hint, then store all relevant registers into the
signature (with the expectation they will be unchanged, as confirmed from Sail). Any register that contains an
address would need to be relocated appropriately prior to being saved (that would be the signature pointer,
primarily, and any CSRs that contain an address such as EPC and TVAL.

The test should be easily updated as new hint functionality is ratified (e.g. Zihintntl).

Deliverables:

• Assembly language tests
• Coverage models using riscv-ctg YAML formatted schema Acceptance criteria

Acceptance Criteria:

• Assembly language tests that meet the TestFormatSpec,
• Tests pass using the riscof framework

Projected timeframe: (best guess date)

SOW Signoffs:

• Task group liaison sign-off date:
• Development partner sign-off date:
• ACT SIG sign-off date (if ACT work):

Waiver

• Freeze
• Ratification

@HAMZA-AFZAL404 can you have a look at it?
@jjscheel you can assign this SoW to 10xEngineers

[HAMZA-AFZAL404]

Ok i am doing it.

@HAMZA-AFZAL404, as you start your work, the 2 most important questions for me is what "size" is this. (See the help text on the Sizing field) and when do you target having a PR accepted by the community. This is the Planning phase work I need to move you to Developing. Please post your thoughts when you have them.

THANKS!

@HAMZA-AFZAL404, an thoughts on my previous questions about size and target completion date?

@jjscheel , @HAMZA-AFZAL404 has been assigned to some other projects in a different team, so he will not be available to work on ACT stuff, we have shelved this one, we will come back to this one in the next quarter

[jjscheel]

Ok. Will set to blocking. Let me know when you have a resource to work on this.
