A computer determines, for one or more paths in a circuit design, for a value of a design variable at which timing closure of the circuit design is achieved, an approximate slope of a function representing path delay as a function of the design variable. When the computer determines that one of the approximate slopes is not within a defined slope range, the computer determines an adjustment direction and an adjustment value based in part on the magnitude by which the slope is not within the defined slope range. The computer changes the circuit design of the path associated with the out-of-range slope, based in part on the adjustment direction and the adjustment value, so as to bring the slope within the defined slope range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit design using design variable function slope sensitivity","description":"A method for designing an integrated circuit.
