+# mlkem_top KAT Testbench
+
+## Goal
+
+编写 `mlkem_top` 的 KAT (Known Answer Test) testbench，使用 FIPS 203 标准测试向量验证 KeyGen/Encaps/Decaps 正确性。
+
+## Data Source
+
+`/home/fallensigh/Dev/ml-kem-r/test_data/kat_MLKEM_512.rsp`
+- 100 个测试向量 (count 0-99)
+- 每个向量包含：d, z, msg, pk, sk, ct, ss
+- NIST FIPS 203 标准格式
+
+## Requirements
+
+1. Python `gen_vectors.py` 解析 KAT 文件，生成 `mlkem_top_input.hex` 和 `mlkem_top_expected.hex`
+2. Verilog `tb_mlkem_top_xsim.v`：
+   - 读取输入向量 (d, z, msg)
+   - 驱动 KeyGen → 验证 pk, sk
+   - 驱动 Encaps → 验证 ct, ss
+   - 驱动 Decaps → 验证 ss
+   - 超时看门狗
+   - pass/fail 统计
+
+## Decisions
+
+* 先用 ML-KEM-512 (k=2)，后续扩展 768/1024
+* 文件向量模式，遵循现有 TB 风格
+* 自检模式：与 KAT 期望值逐个字节比较
+
+## Test Flow (per vector)
+
+1. 复位
+2. KeyGen: d → verify pk, sk
+3. Encaps: msg → verify ct, ss
+4. Decaps: ct → verify ss (output matches ss from encaps)
+
+## Acceptance Criteria
+
+* [ ] 至少 count=0 的 KeyGen 通过
+* [ ] 至少 count=0 的 Encaps 通过
+* [ ] at least basic Decaps consistency
+* [ ] xvlog 编译通过
+* [ ] xsim 仿真通过
+
+## Out of Scope
+
+* 全部 100 个向量（先做前 5 个）
+* ct_n 无效密文测试
+* ML-KEM-768/1024
