Re: "Microprocessor designers always create "spare gates" (unused logic) which connect to top level metal layers, to allow for metal only logic changes. It is standard practice to fix speedpaths and bugs with available spare logic, many times involving only one metal layer."

These "bonus gates" are there for logic fixes but don't usually get used for speedpath fixes because they just add more gate delays.
