[myhdl-list] TypeError: Unexpected type with toVerilog

[Thoma H. <tho...@gm...>]

Hi,

I am new to myHDL and it seems to be a powerful tool.
Today, I need some help to locate the reason of the below exception.
Because there are no clue to indicate the line of the issue, I am 
currently blocked in my evaluation of myHDL.

Thank you in advance.

Thoma
