SikongJueluo	f71bf06484	feat(hw): add XNOR-popcount CAM design with cocotb verification ... Implement a multi-lane Content Addressable Memory (CAM) that scores rows by XNOR popcount against a query hash and returns the top-1 match. RTL modules: - popcount: parallel group-based population count - argmax_update: iterative best-match tracking with tie-break - cam_core: parameterized scanning engine (NUM_ROWS/HASH_BITS/LANES) with optional SIM_NOISE and SIM_DEBUG ifdef guards - cam_top: thin wrapper exposing cam_core ports Verification: - Python reference model (ref_model.py) for score-level golden comparison - cocotb testbench (test_cam_basic.py) covering write/query/reset and external noise mask scenarios with score debug verification - Noise sweep script (sweep_noise.py) measuring top-1 stability under configurable bit-flip rates - Verilator-oriented Makefile with parameterizable compile options	2026-05-02 23:26:16 +08:00
SikongJueluo	ad45123022	chore: migrate habitat dependencies to conda and add cocotb for hardware verification ... - Move habitat-baselines and habitat-lab from pip to conda environment - Add cocotb and cocotb-tools to pyproject.toml dependencies - Update ty environment roots to include hw/sim directory - Add sim/sim_build to gitignore - Create CLAUDE.md with project spec, coding guidelines, and directory structure - Update uv.lock to reflect dependency changes	2026-05-02 23:24:59 +08:00
