SikongJueluo	424cf6e1d3	refactor(hw/sim): reorganize CAM top-level tests into per-noise-config suites ... Split the monolithic test_cam_basic.py into separate test suites organized by noise configuration (no_noise, write_noise, read_noise), with shared utilities extracted to tests/top/utils.py. - Remove test_cam_basic.py; add no_noise/, write_noise/, read_noise/ test suites with Makefiles that set noise parameters statically - Extract helpers (reset_dut, write_rows, query_once, collect_topk, etc.) into tests/top/utils.py - Update hw/sim/Makefile with per-config test targets and a test-top-all meta-target - Update scripts/run_cam_correctness.py to build per-directory instead of centrally, removing inline parameter overrides - Add __init__.py for result_serializer and topk_tracker module tests - Expand docstrings in test_ref_model_noise.py with architectural context and test rationale	2026-05-21 21:22:12 +08:00
SikongJueluo	e4cbb5e30d	feat(hw/rtl): implement full Top-K CAM search pipeline with serial result output ... - add TOPK_K, FIFO_DEPTH, RESULT_SERIAL parameters to cam_params - add candidate_fifo: synchronous ready/valid FIFO for (row, score) candidates - add topk_tracker: tracks top-K candidates with clear/ready handshake - add result_serializer: serializes packed Top-K array into rank-ordered stream - refactor match_engine_pipeline from 4-state to 8-state Top-K pipeline - extend cam_top with serial Top-K interface (result_rank/row/score/last) - add backward-compatible top1_index/top1_score aliases from rank-0 beat - add comprehensive tests for all new modules	2026-05-19 22:43:21 +08:00
