Hello everyone,

As far as I can see, there is no action on this topic anymore. I'm
currently encounter a Problem with exactly this.
My Problem is, that I have some (cpu-)modes, which I'd like to have in
an extra file, because I use them from some points in my code. So I
create a file cpumode.py with the following content:

cpumode.py:
> class CpuMode(object):
>     User = 0b10000
>     FIQ = 0b10001
>     IRQ = 0b10010
>     Supervisor = 0b10011
>     Abort = 0b101111
>     Undefined = 0b11011
>     System = 0b111111

In the next file, I import it via

> from cpumode import CpuMode


Now, myhdl tells me:

> myhdl.ConversionError: in file xxx.py, line 63:
>     Unsupported attribute: User

line 63:
> if mode == CpuMode.User:

This is garbage... :/ If I declare User outside of the class, but
directly in the cpumode.py, the same error occurs. Only iff I delcare
User, FIQ, IRQ, ... in the same file (in this case xxx.py) it will work.

Is there any way out or thoughts about implementing a enum with given
values? (In the thread, there was a tought about exporting the Enum
class and create it via that :/

Greetings,
Marcel
