        @yx9527 后面出个参考软件给大家，自己跑吧 😃
        说实话，目前曲线上结果不是太好，别期望太高哦。正在进一步改进中

          @bo 范老师，C Model大概什么时候发布？会发布源代码吗？

            @fighting C Model暂时不开放源代码，会对参与项目开发的人员开放代码。一般用户其实只需要RTL就够了

              范老师，您好！ 我一部分工作是作视频处理算法的，从事IC设计有十余载，希望有机会可以参与贵团队的工作，无论编码、设计、架构、优化都可以。 真的非常高兴国内有越来越多这样的共创平台。

                我用synopsys － DVE （or say VCS） 将仿真跑起来了，目前run 正常无报错

                    范老师, 如果真想拿个asic SoC 项目把这个VENC 集成进去
                    －－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；
                    跑一跑SoC的top仿真，
                    以及放到emulator上也就是用FPGA搭建的emulation的环境上跑跑的话，
                    还是需要更多测试例的，如果能开放相应的C model就好了，
                    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。
                    我真的非常急切渴望知道和确定RTL代码的实际可用性！

                          @bo ，can you share cmodel or x265,which we can compare your encoder performance with others!

                                范教授您好，我是一名视频编解码的学习者，想问下您能否提供一份这个Encoder IP CORE的说明文档呢？

                                      你好范老师。
                                      我下载代码在vcs下仿真通过。但有几个问题请教下。
                                      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？
                                      2.sao是否只支持band，没有edge？
                                      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。
                                      4.你们是否有帧压缩的内容？

                                      谢谢！

                                        @bytree1 目前sao没支持edge， LCU只能是64的 32的没支持，帧压缩没支持
