Abstract
A method includes operation below: extracting layout patterns that include interconnection layers between a first terminal and a second terminal coupled to the first terminal, in a layout design of a circuit; comparing a first portion of the layout patterns with a first coding portion that specifies a first layout constraint, in which the first portion of the layout patterns is extracted in a sequence starting from the first terminal or to the first terminal; comparing a second portion of the layout patterns with a second coding portion that specifies a second layout constraint, in which the second portion of the layout patterns is extracted in a sequence from the second terminal or to the second terminal; in response to comparisons, initiating fabrication of at least one element of the circuit according to the layout design.
