A method of forming and electrical structure. The method includes determining that a first semiconductor device requires an engineering change order (ECO). An additional structure layer required to implement the ECO is determined. A first insertion point location for inserting the additional structure layer within the first semiconductor device is selected. The first insertion point location is associated with a second insertion point location within a design for a second semiconductor device. The second semiconductor device is generated in accordance with the first ECO. The second semiconductor device comprises second structures. The second structures comprise same structures as first structures in the first semiconductor device. The second structures are formed in locations within the second semiconductor device that are associated with locations in the first semiconductor device comprising the first structures. The second semiconductor device comprises the additional structure layer located within the second insertion point location.

A method is provided for updating an existing netlist to reflect a design change. A register transfer level (RTL) design incorporating the design change and the existing netlist are provided to a synthesis tool. The existing netlist is set to a read-only condition to prevent a change to the existing netlist. The design and the read-only existing netlist are processed with the synthesis tool reusing logic structures from the read-only existing netlist by performing an optimization of the design and the read-only existing netlist with an objective to minimize the design space. The optimization is constrained by the read-only existing netlist. A result is generated by the synthesis tool including the existing netlist and a new portion of a netlist reflecting the design change.
