Re: [myhdl-list] help - hot bit encoder

[Jan D. <ja...@ja...>]

Jan:

Sorry for the delay in responding - I'm not very motivated
to make things more complex than needed :-)

Anyway, I understand you want to investigate and learn,
but in that case, please read the manual. I wrote it
for you :-)

http://www.myhdl.org/doc/current/manual/conversion.html#supported-types

It clearly states that the kind of thing your are doing
with object 'map' is just not supported by the converter.
As I keep repeating, conversion is really very restricted.
We really should be discussing anything you don't understand
or is unclear in the manual. Your starting assumption should
be that almost nothing inside a generator is convertible :-)
Don't just keep on trying and be frustrated - first read
about the restrictions in the manual.

Of course, it remains a software bug to let assertions
escape to the user, and I have now added a clearer error
message in development.
