Fit data: AGGRESSIVE AREA gives design clk +0.631 / EMIF -0.103; global BALANCED flipped it to EMIF +0.084 / design clk -6.119 (vert_count->texcache swung 6.7ns). AGGRESSIVE AREA is far closer to closing, so keep it and fix the one 310MHz EMIF miss surgically: MAX_FANOUT 3 on u_zc_emit|u_req|raddr_hi1_q forces the register duplication Quartus asked for (TMC-20551) without the global placement disruption.

retroDE_ps2 Planning Docs
This directory is the working design scaffold for the PS2 core.
Purpose:
- define the intended repository shape before RTL lands,
- define subsystem boundaries before implementation choices harden,
- document what each block owns, what crosses the boundary, and how we will validate it.
Recommended reading order:
- repo_layout.md
- phase0_checklist.md
- contracts/README.md
- stub_module_plan.md
- wave2_dma_gif_plan.md
- wave25_memory_backed_dma_plan.md
- wave26_multi_beat_dma_plan.md
Relationship to references/:
references/is the research library.docs/is the project-definition layer.
Rule of thumb:
- If a file explains PS2 hardware as it exists, it belongs under
references/. - If a file explains how
retroDE_ps2intends to model, partition, or validate that hardware, it belongs underdocs/.
