• Test plan for the scalar-crypto specific instructions is available.
• Imperas have a complete set of tests, written to the existing test plan, for the scalar crypto instructions and the bitmanip instructions we borrow.
  • These have been merged into the main test suite as of PR#177, with many thanks to Imperas for the contribution.
    • Spike, OVPSim and Sail all agree on the test signatures.
  • They form a base we can use to develop prototype implementations / Spike / SAIL / QEMU very easily and quickly.
• Upstream Spike support for enabling it to work with the K test suite is being added in PR#687.
• IIT Madras are also looking at writing the scalar crypto tests for integration into the official architectural tests repo as well.
  • Agreed SoW for IITM
  • They are re-implementing the tests as part of the blessed coverage and test generation tooling.
    • Making good progress with the simple test patterns for scalar-crypto specific instructions A/O April 7'th '21
  • We then switch over to using the IIT tests when they are finished, since they will be easier to maintain/extend going forward than the Imperas tests.
• YAML config changes for K have been merged in. See here.
• Status from IIT Madras as on 05-May:
  • Resolved issues in running the rv64ik toolchain after interacting with PLCT and compile the relevant tests generated from CTG and run them on spike
  • Currently resolving issues in the running the rv64ibk toolchain. Once this is done, will generate the coverage report of the test cases built till now and share with team.
• Status from IIT Madras as on 26-Apr:
  • Completed the coverage points specification for all 32-bit and 64-bit instructions
  • Generated test cases from the coverage points
  • Currently working on trying to install the scalar crypto enabled toolchain.
