Accommodating engineering change orders in integrated circuit design

A computer-implemented method, comprising:

• receiving a register-transfer-level description and a gate-level description for an integrated circuit design, wherein said gate-level description comprises one or more spare latches implemented as reconfigurable latch filler cells;
• receiving an engineering change order for said integrated circuit design, wherein said engineering change order requires at least one additional latch;
• responsive to said engineering change order, adding said at least one additional latch to said register-transfer-level description;
• for at least one of said at least one additional latch, selecting one of said one or more spare latches in said register-transfer-level description to yield a selected spare latch;
• for said selected spare latch, identifying a selected reconfigurable latch filler cell in said gate-level description;
• replacing said selected reconfigurable latch filler cell with an operational latch in said gate-level description;
• and
• finalizing said integrated circuit design.

A method of producing an integrated circuit comprising:

• producing an integrated circuit design;
• adding at least one spare latch design to said integrated circuit design;
• replacing at least one of said at least one spare latch design with a reconfigurable latch filler cell design;
• and
• manufacturing said integrated circuit design.
