I have tried doing the following:
def elaborate(self, platform):
    m = Module()
    width = yield self.width
    rs = yield self.rs
    ra = yield self.ra
    rb = yield self.rb
    print("width: ", width, "rs: ", rs, "rb: ", rb, "ra: ", ra)

Which unfortunately does not print the values, but gives me the following
File "/home/colepoirier/src/nmigen/nmigen/hdl/ir.py", line 50, in get
    raise AttributeError("Object {!r} cannot be elaborated".format(obj))
AttributeError: Object <generator object Bpermd.elaborate at 0x7f1f4ca00750>
cannot be elaborated

What am I doing wrong?
