1. A system, comprising:

  • a processor; and

    memory having stored thereon instructions that, when executed by the processor, cause the processor to;

    analyze timing data of an integrated circuit, wherein the timing data includes transition times for cells along paths of the integrated circuit;

    identify instances of timing degradation for the cells along the paths of the integrated circuit in which an output transition time is higher than an input transition time;

    recommend changes for the instances of the cells along the paths having timing degradation, wherein if a length of a path having timing degradation exceeds a first threshold value or a number of inverters or buffers succeeding the path having timing degradation exceeds a second threshold value, split the path into a resistance critical path or a capacitance critical path and assigning a non-default rule to the resistance critical path or the capacitance critical path;

    generate at least one file for fabricating an integrated circuit in accordance with the recommended changes; and

    fabricate, or cause to be fabricated, an integrated circuit in accordance with the at least one file.
