Abstract
A method includes receiving a register-transfer-level description and a gate-level description for an integrated circuit design. The gate-level description includes one or more spare latches implemented as reconfigurable latch filler cells. The method further includes receiving an engineering change order, and, responsive to the engineering change order, adding the at least one additional latch to the register-transfer-level description and, for at least one of the at least one additional latch, selecting one of the one or more spare latches in the register-transfer-level description to yield a selected spare latch. The method further includes, for the selected spare latch, identifying a selected reconfigurable latch filler cell in the gate-level description and replacing the selected reconfigurable latch filler cell with an operational latch in the gate-level description. The method further includes finalizing the integrated circuit design. A corresponding computer program product and computer systems are also disclosed.
