Re: [myhdl-list] how to make list of unequal-sized signals

[Samuele D. <sm...@gm...>]

Hi,
I am just a new user of MyHDL.
But for what I understand lists of signals must have same type (see
hardware oriented types docs). You can use an interface to group different
Signals. You will lose the ability to index them. Is it fine?
You could try to implement indexing on an interface in MyHDL sources. That
would be the proper solution.
There are also some bad hacks you can do with python using locals(). What's
your purpose?
