ZynqNet解析（二）运行与调试

背景：ZynqNet能在xilinx的FPGA上实现deep compression

目的：运行zynqNet的代码。

源码地址：https://github.com/dgschwend/zynqnet

项目程序架构，针对我们的项目，我们需要看懂相应的HLS程序和ARM端的程序。

ARM端的程序以_FIRMWARE为准；FPGA端程序以HLS为准。

1. _TRAINED_MODEL
这部分为训练好的caffe模型与预训练的权重。

2. _FIRMWARE
这部分程序针对Zynq 7Z035 ARM processor。make之后是在服务器上运行的，一次迭代需要将近3590ms

make
./test CPU|FPGA indata.bin (-quiet)

2.1 运行打印结果

TestBench Result: SUCCESS

若参数输入FPGA则在分配完mem之后打出
XFPGA Driver: Initialize
test: could not open /dev/mem. need to be root: Permission denied

3._HLS_CODE
3.1 C simulation
这部分代码为用于进行HLS的c代码，其中fpga_top为top-level function，cpu_top为其test Bench。我们在运行时，前面正常输出，但是到了c10/p1在进行FPGA :computing的时候，会给出报错SIGSEGV，可能为内存相关的问题。

3.2 Synthesis
这部分排除了两个BUG，一个是在unittests.cpp程序中，这个程序用于测试相关的单元的功能。行中的显示没有seiosflags，我们发现这行作用并不大，直接删掉。
// unittests.cpp line 50
std::cout << std::setiosflags(std::ios::fixed) << std::setprecision(2)
<< "ERROR: " << acquired << " != " << expected << " in " << fn
<< " (" << file << ", line " << line << ")" << std::endl;

另一个BUG是在netconfig.cpp 中，给出报错没有fopen，printf等等的函数，我们直接在其加入 #include。对于程序的其他问题我们需要在后续继续阅读与搞懂程序。

综合通过，然后export RTL

3.3 搭建系统与生成比特流

我们添加PS，定制PS 加入HP0，时钟周期设为200MHz，加入中断并连接，然后自动连接。
