以下代码片段显示了 Python 关联环境中的 API 使用方式。
您需要按如下方式设置 PYTHONPATH：
- 例如，在 C Shell 上：
setenv PYTHONPATH $XILINX_VIVADO/data/emulation/hw_em/lib/python: $XILINX_VIVADO/data/emulation/ip_utils/xtlm_ipc/xtlm_ipc_v1_0/python - Python 主机的代码片段：
aximm_payload = xtlm_ipc.aximm_packet() random_packet(aximm_payload) # Custom function to set AXI Properties randomly #Or user can set AXI properties as required #aximm_payload.addr = int(random.randint(0, 1000000)*4) #aximm_payload.len = random.randint(1, 64) #aximm_payload.size = 4 master_util.b_transport(aximm_payload) #After this call aximm_payload will have updated response as set by the AXI Slave. - Python 从机的代码片段：
aximm_payload = slave_util.sample_transaction() aximm_payload.resp = random.randint(0,3) if not aximm_payload.cmd: #if it is a read transction set Random data tot_bytes = aximm_payload.len * aximm_payload.size for i in range(0, int(tot_bytes/SIZE_OF_EACH_DATA_IN_BYTES)): aximm_payload.data += bytes(bytearray(struct.pack(">I", random.randint(0,60000)))) # Binary data should be aligned with C struct slave_util.send_resp(aximm_payload)
