🎯 L-DPC1 Hardware Bench — CLOSED ✅
GF16 dot4 с phi-константами и 3-фазный phi-heartbeat верифицированы одновременно на реальном железе XC7A100T.
Verified on hardware (2026-05-10)
Файлы (fpga/vivado/)
gf16_add.v— GF(2⁴) сложение: побитовый XORgf16_mul.v— GF(2⁴) умножение: LUT-based, polyx⁴+x+1(0x13). No DSP48 — abc9 routing issue (tracked separately)gf16_dot4.v— 4-элементный dot product с параметрическими phi-константамиgf16_heartbeat_top.v— топ-модуль: phi-heartbeat (3-phase) + gf16_dot4 + STARTUPE2.CFGMCLKToolchain

W0..W3) — легко менять для разных экспериментов.Next steps (не в этом PR)
$readmemh— после решения DSP48 routingsim/) для gf16_mul и gf16_dot4
