What worked.
What didn’t.

Notes from my RTL, verification, and architecture work. What passed, what failed, and what I need to check before I draw a conclusion.

A failed baseline is still useful information.

VIGIL’s checker units pass their focused tests, but the full M0 regression hasn’t passed yet. The latest runtime result is inconclusive. I need to get the baseline working and rerun it before I can say anything about reliability.

These numbers are still goals.

PULSAR-4X aims to combine four 500 MS/s channels for 2.0 GS/s total. There’s no implementation or measurement yet, so treat that figure as a target, not a result.

The fixed-point details matter.

MHDA’s reported gain and hardware/software error only make sense alongside the fixed-point behavior and simulation setup that produced them. Without those details, it’s hard to reproduce the numbers.

I want to understand the whole flow.

I’m learning how RTL decisions affect synthesis, timing, physical design, and testing. Scripts and repeatable checks help me retrace how I got each result.
