SikongJueluo	97e53d44f8	feat(hw/sim): distinguish query-only and end-to-end performance cycles in retrieval benchmark ... Add explicit separation between query-only cycles (accept→last) and end-to-end cycles (load + write + noise + queries) in hardware retrieval benchmarks. - Add query_only_cycles_per_query, load_write_noise_cycles, end_to_end_cycles metrics - Refactor summarize_query_timings() to use accept_to_last_result_cycles as query-only base - Add build_hardware_performance() to compute end-to-end performance separately - Add current_sim_cycle() helper using cocotb get_sim_time - Update CSV/Markdown outputs and RETRIEVAL_PERF_RESULT log format - Update documentation to clarify cycle-counting methodology - Update tests to cover new performance measurement logic	2026-05-29 18:49:05 +08:00
SikongJueluo	42d4a9728d	feat: add hardware retrieval cycle performance measurement ... Add cycle-level performance measurement for hardware CAM retrieval benchmarks to complement existing quality metrics. - Add query_topk_once_with_latency with accept→first/last cycle timing - Add QueryTiming dataclass and summarize_query_timings helper - Integrate cycle performance into benchmark outputs (CSV + Markdown) - Log RETRIEVAL_PERF_RESULT with cycles/query and queries/cycle - Update experiment docs with hardware cycle performance section - Add unit tests for summarize_query_timings and output writers	2026-05-28 13:05:34 +08:00
SikongJueluo	29f4cc91f6	fix(pipeline): add S_WAIT_READ_RESP state to fix read-noise PRNG timing ... - Emit rd_valid_o for exactly one combinational cycle before waiting for read response, ensuring the read-noise PRNG advances once per batch issue - Fix query handshake: wait for query_ready before asserting query_valid to avoid valid&&ready handshake drops on clock edges - Add dynamic timeout estimation in test utilities based on DUT parameters - Update test-top Makefile to run all noise configurations by default - Remove uv run prefix from cocotb-config Makefile invocation	2026-05-22 19:04:50 +08:00
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
