How debugging TPM issues with WHLK

Hello,
I'm currently running the WHLK on a TPM, and would like to understand why some tests are failing.
As the TPM is under development the error is much probably on the TPM side, but as I don't know what the tests are doing exactly it's very tricky.
Ideally I would need a way to enable as much logs as possible (to see what tpm commands are sent) - today I'm doing it with an spi analyser with a home made tpm interpreter ...
Is there also any way to have access to the source files of the tests (or a doc)? I'm currently relying only on the run logs (Te.wl) which are not sufficient to know at which step the test fail exactly.
