我下载代码在vcs下仿真通过。但有几个问题请教下。<br />
1.看top.v中，cabac模块的sao_in直接接0，等于说自带平台不支持sao。如果想支持的，如何修改？<br />
2.sao是否只支持band，没有edge？<br />
3.我尝试修改enc_define的LCU大小，从64变成32，但是编译时发现，不少代码还是按64的大小编写的，直接编译会报out of boundary。<br />
4.你们是否有帧压缩的内容？</p>
<p dir="auto">谢谢！</p>

－－这其实也是件很快的事情，因为我本来就有这样的SoC项目，用的是verisillicon的h.265；<br />
跑一跑SoC的top仿真，<br />
以及放到emulator上也就是用FPGA搭建的emulation的环境上跑跑的话，<br />
还是需要更多测试例的，如果能开放相应的C model就好了，<br />
我可以将C model 修改得更接近UVM平台 得架构， 对关键模块及节点进行自动化实时数据对比。<br />
我真的非常急切渴望知道和确定RTL代码的实际可用性！</p>
