SikongJueluo	2da17e101b	feat(rtl): migrate CAM interface to handshake protocol with integrated noise generation ... BREAKING CHANGE: CAM write and query interface replaced with standard valid/ready handshake. wr_en/wr_row/wr_hash → wr_valid/wr_ready/wr_addr/write_hash. External noise_mask_lanes_flat removed; noise generation now handled internally by cam_noisy module with configurable rate via parameters. - cam_top: add parameters (NOISE_EN, NOISE_RATE_NUM/DEN, NOISE_GEN/SAMPLE_BITS, NOISE_SEED) - cam_top: replace cam_core with cam_noisy (integrated noise generation) - match_engine: remove external noise_mask_lanes_flat input - hw/sim: update Makefile with noise parameters and compile args - hw/sim/model: add generate_write_flip_mask() and xorshift64() matching RTL behavior - hw/sim/tests: adapt testbench to new handshake protocol	2026-05-04 18:03:06 +08:00
SikongJueluo	f5daaa2667	refactor(cam): extract match engine into separate module and centralize parameters ... - Split cam_core into pure memory (cam_core.sv) and match engine (match_engine.sv) - Add cam_params.svh with centralized parameter definitions (NUM_ROWS, HASH_BITS, LANES, etc.) - Update cam_top.sv to use shared parameters and compose match_engine - Update Makefile to include new match_engine module and correct Verilator define syntax	2026-05-02 23:28:32 +08:00
