Before we get started on this, I'd like to make sure we complete the SOW. @ptprasanna, can you propose some text and place in a comment for review?

[ptprasanna]

Majority of the codes changes are done as part of Zfinx, so have to check the double precision floating tests on integer registers, which are expected to run on the current code changes (Through the PR is merged yet), may require a minor fixes on the framework with respect to "ISAC" and "CTG". Bit of a test driven changes we may have to carry ahead.

[ptprasanna]

All the work related to Zdinx are completed with 100% coverage, now peer reviewing the reports. Also this has a dependency with the previous PR (zfh and zfinx) to be merged before raising a new PR for this work.

All the work related to Zdinx are completed with 100% coverage reports. This has a dependency with the previous PR (zfh and zfinx).

Zfinx and Zfh PR for ISAC has been merged.
riscv-software-src/riscv-isac#72

Zfinx and Zfh PR from CTG has been waiting for review.
riscv-software-src/riscv-ctg#67

Previous PR(Zfinx and Zfh) to be merged before raising a new PR for this work.

[anuani21]

@jjscheel,

Once Zfinx and Zfh PR from CTG has merged, I will raise a PR for Zdinx ACT.

[jjscheel]

Understand.

@allenjbaum, waiting here too.

[jjscheel]

@anuani21, I know that we are waiting for the PR in #17 and #18 to be accepted before building this PR. Given that we continue to wait for something, would it be worth our time to at least build this PR (assuming acceptance of the Zfinx and Zfh work) and submit for comment? Then, we could simply declare this "done" (or permanently blocked) and move on.
