.. todo:: Add information about `$alu`, `$fa`, `$macc_v2`, and `$lcu` cells.
The `$macc` cell type represents a generalized multiply and accumulate
operation. The cell is purely combinational. It outputs the result of summing up

Where before each type of arithmetic operation had its own cell, e.g. `$add`, we

now want to extract these into `$alu` and `$macc_v2` cells which can help identify
opportunities for reusing logic. We do this by running `alumacc`, which we can
see produce the following changes in our example design:
