FallenSigh	d4c3fc86fc	feat(tb): add Vivado XSIM Verilog testbenches for all 10 sync modules ... Add file-based vector testbenches ( + ) for: - mod_add_sync, rng_sync, poly_arith_sync, comp_decomp_sync - s_bram/sd_bram, sha3_chain_top - ntt_core, poly_mul_sync - sample_cbd_sync, sample_ntt_sync Each module includes: - tb_<module>_xsim.v: Vivado XSIM testbench - gen_vectors.py: Python vector generator (stdlib only) - vectors/<module>_input.hex: test input vectors - xsim_run.tcl: compile + elaborate + simulate script	2026-06-25 20:48:38 +08:00
FallenSigh	209ca90fb1	feat(poly_arith): implement synchronous PolyAdd/PolySub streaming module ... Phase 2.3: Polynomial modular addition and subtraction. - poly_arith_sync.v: mode=0 add (a+b mod Q), mode=1 sub (a-b mod Q) - Pure streaming (1 coeff/cycle, no BRAM needed) - Uses pipeline_reg for valid/ready handshake Verified: 10/10 vectors bit-exact vs Python reference	2026-06-24 23:12:59 +08:00
