Re: [myhdl-list] Dynamic ports

[Christopher F. <chr...@gm...>]

I would try something like the following - I have
not tested this thoroughly but something like this
should get you where you need to be.

In [116]: def m_top_vargs(**portmap):
      ...:     # need a method to locally reference all the
      ...:     # ports passed, example
      ...:     xcnt = sum([1 for k in portmap if 'x' in k])
      ...:     locallist = [Signal(intbv(0)[12:]) for _ in range(xcnt)]
      ...:     sel = portmap['sel']
      ...:     y = portmap['y']
      ...:     xi = 0
      ...:     for k,v in portmap.iteritems():
      ...:         if 'x' in k:
      ...:             locallist[ii].assign(v)
      ...:             xi += 1
      ...:     print(locallist)
      ...:

In [117]: portmap = {'sel': Signal(intbv(0)[4:]),'y': Signal(intbv(0)[21:])}
      ...: for ii in range(8):  # for the number of inputs
      ...:     portmap['x%d'%ii] = Signal(intbv(0)[21:])
      ...: m_top_vargs(**portmap)
      ...:
[Signal(intbv(0L)), Signal(intbv(0L)), Signal(intbv(0L)), 
Signal(intbv(0L)), Signal(intbv(0L)), Signal(intbv(0L)), 
Signal(intbv(0L)), Signal(intbv(0L))]
