Engineering Change Order, used when a chip is going to tape out, for small logic changes and fix timing, x-talk etc.

Engineering Change Order or ECO is the process of inserting logic directly into the gate level netlist corresponding to a change that occurs in the rtl due to design error fixes or a change request from the customer. ECO is preferred as they save time and money in comparison to a full chip re-spin.
