Function fifo_control_verilog 

pub fn fifo_control_verilog(name: &str, depth: usize) -> String

A page FIFO’s control, module name: depth pages, and the reservations, pushes, waits and pops that are the IR’s ops — free, count, the slot the next fill takes and the slot the next read takes. Its pages live in the pool memory its phase colors it into (site_pools).
