--- Comment #7 from Staf Verhaegen <staf at fibraservi.eu> ---
After reading a little further I think that the architecture was developed at a
moment where not the current synthesis, place-and-route and timing check tools
were available. With current tools I think it is better to implement it all on
the DependencyMatrix level without sublevels. Incomplete and non-checked code:

    class DependencyMatrix(Elaboratable):
        def __init__(self, n_fus, n_regs):
             self.fu_start = Signal(n_fus)
             self.fu_read_in = Array(Signal(n_regs) for _ in range(n_fus))
             self.fu_write_in = Array(Signal(n_regs) for _ in range(n_fus))
             self.fu_read_ok = Signal(n_fus)
             self.fu_read_done = Signal(n_fus)
             self.read_reserve = Signal(n_refs)
             self.fu_write_ok = Signal(n_fus)
             self.fu_write_done = Signal(n_fus)
             self.write_reserve = Signal(n_refs)


        def elaborate(self, platform):
            m = Module()

            matrix_fu = Array(

            return m
{{{python
import sys
}}}
