thejayman77 ec82764bef Initial commit: retroDE_ps2 — first-of-its-kind PS2 GS FPGA core (DE25-Nano / Agilex 5)
RTL (GS rasterizer, EE core stub, platform bridge, LPDDR4B path), sim regression
(272 TBs), docs, and tooling. Copyrighted PS2 content (BIOS, game code, GS dumps,
and all dump-derived textures/traces) is excluded via .gitignore and stays local.

sim/tb/integration

Cross-subsystem integration testbenches that exercise full pipelines end to end. Distinct from the per-subsystem testbenches in sibling tb/<subsys>/ directories — those prove one block in isolation; these prove a chain.

Wave 2 contents

  • tb_bgcolor_via_dma.sv — "programmable BGCOLOR via DMA/GIF" (Milestone A+). Chain: dmac_reg_stub → gif_path_stub → gs_stub → platform_video_stub with four trace sinks. Configures DMAC channel 2, provides a one-qword project-local packet carrying a BGCOLOR register write, verifies the color propagates through to the raster output.

See docs/wave2_dma_gif_plan.md for the Wave 2 scope and the packet format.
