Hmmm, yes this doesn't appear to be currently supported,
that is accessing attributes in a combinatorial function.
Not sure why it is not?

Could you use a module instead of a function?

     rb_inst = register_bank(mode, mul)

     @always_seq(clk.posedge, reset=reset)
     def write():
         # ...
         re = regbank[mul*18 + rs]

     @always_comb
     def read():
         re = regbank[mul*18 + rs]

     return rb_inst, write, read
