unsupport concat type when parse dataflow.

[hunterzju]

Thanks for your excellent work, but I found it unsupport some operation when parse dataflow graph. The error message it returns is :

File "/usr/local/lib/python3.5/dist-packages/pyverilog-1.1.3.dev0-py3.5.egg/pyverilog/dataflow/bindvisitor.py", line 1339, in getDst
    (str(type(left)), str(left)))
pyverilog.utils.verror.FormatError: unsupported AST node type: <class 'pyverilog.vparser.ast.Concat'> <pyverilog.vparser.ast.Concat object at 0x7fa687524f98>

it seems that the function getDst in dataflow/bindvisitor.py does not support vparser.ast.concat operation. My verilog source code in attach files. And the top module I want parse is one_round module. verilogsrc.zip Hope the tool could be better and I can also do something for the project if possible.

你好，请问你也使用pyverilog编译AES设计了吗？我想编译AES，并获得其dataflow，结果跑了好久都没出结果。但我跑uart的时候，很快。请问你知道为什么吗？

可能是有解析过程有环，导致无限循环了，貌似pyverilog对有环的情况处理不太好，可以top命令看一下是不是进程一直在吃内存。

那你最后跑出来了嘛？我现在需要提取verilog设计中的数据流，我自己写不来编译器，只能找轮子，他这个感觉还可以哦发自我的华为手机-------- 原始邮件 --------主题：Re: [PyHDI/Pyverilog] unsupport concat type when parse dataflow.

Hi, could you use English, please?

Sorry, we are discussing the problem we met when parse AES module using pyverilog : the memory expand but can not return a result. I guess maybe there is a ring in the module and pyverilog came into a dead loop, but I have no idea how to solve it. Sorry again for our behavior.

Sorry

I encounter the same situation. The dataflow analyzer cannot parse AES crypto core. Do you guys have any solution?

hi bro, could you fix the problem if you can tell me by this email [email protected] thanks a lot
