Analog ECO Flow

A non-transitory computer-readable medium encoded with memory storing instructions for fabricating an integrated circuit, which when executed result in operations comprising:

• initiating an auto-marker process to fill-in an initial circuit design with a plurality of ECO cells, thereby forming an updated design;
• inserting dummy patterns, wherein the dummy patterns are configured to prevent dishing during fabrication;
• performing a final design rule check (DRC);
• performing RC-extraction and post-layout simulations;
• and
• causing an integrated circuit to be fabricated from the updated design.

A computer-implemented system for making a design change to an integrated circuit, comprising:

• one or more processors;
• and
• computer-readable memory in communication with the one or more processors and encoded with instructions for commanding the one or more processors to execute steps comprising:
• receiving an input design comprising a plurality of active cells;
• inserting ECO cells into the design via an analog ECO flow to form an updated design;
• fabricating an integrated circuit based on the updated design;
• implementing an ECO by routing at least one ECO cell of the updated design to at least one active cell of the updated design, thereby creating a revised design;
• and
• fabricating a revised integrated circuit based on the revised design.
