cool, saw that.  so, next, you'll need to run the unit test and sort this:

python3 test_mul.py
Traceback (most recent call last):
  File "test_mul.py", line 38, in <module>
    run_simulation(dut, testbench(dut), vcd_name="test_mul.vcd")
  File "/home/lkcl/src/riscv/nmigen/nmigen/compat/sim/__init__.py",
line 15, in run_simulation
    fragment = fragment_or_module.get_fragment()
  File "/home/lkcl/src/libreriscv/ieee754fpu/src/add/fmul.py", line
44, in get_fragment
    m.d.comb += a.v.eq(self.a.v)
AttributeError: 'FPMUL' object has no attribute 'a'
