Re: [myhdl-list] Examples of using classes?

[Jeremy H. <jer...@gm...>]

Hi Chris,

I was thinking of using inheritance in defining interfaces using classes
like so:

class FIFO(object):
...

class AXIFIFO(FIFO):
...

class WishboneFIFO(FIFO):
...

Or even mixins:

class FIFO(object):
...

class AXI4SSlaveMixin(object):
...

class AXI4SMasterMixin(object):
...

class AXIFIFO(FIFO, AXI4SSlaveMixin, AXI4SMasterMixin):
...

Does this make sense? I'd basically like to be able to drop the
AXI4SSlaveMixin and replace it with WishboneSlaveMixin and have it "just
work".

Thanks,
Jeremy
