Contract Docs
These files define subsystem boundaries for retroDE_ps2.
Each contract should answer:
- what the block owns,
- what enters and exits the block,
- what timing or ordering guarantees matter,
- what is allowed to be stubbed early,
- what must be true before software is expected to progress.
These are design contracts, not user documentation.
Contract maturity levels:
Draft: planning-first, expected to change.Locked for Phase N: stable enough to implement against for that phase.
Current status:
- All files in this folder are
Draft. - Current contract set includes a dedicated interrupt-controller contract in
intc.mdto keep ownership explicit across EE-visible subsystems. sio2_pad.mdis a Ch233 recon contract — no RTL yet — sketching how the Ch222 HPS-side input latches will become a PS2-sidesio2_input_stubwith an IOP-readable pad-state register set in a future implementation chapter.
