Method, electronic design automation tool, computer program product, and data processing program for creating a layout for design representation of an electronic circuit and corresponding port for an electronic circuit

A method performed by a computer for creating a layout for design representation of an electronic circuit with at least one port, comprising steps of:

• the computer segmenting said at least one port in said design representation into different regions;
• the computer classifying said different regions of said at least one port according to at least one of timing, electronic and layout characteristics;
• the computer forming assigned priorities and classified regions by assigning a priority for each classified region of said at least one port according to rules based on said at least of one timing, electronic and layout characteristics;
• and
• the computer routing said design representation by accessing at least one of said classified regions of said at least one port according to an order of said assigned priorities, wherein for each port region of said electronic circuit, at least one of allowable maximum slew, maximum timing error, maximum slew error, and maximum electromigration is set to be a rule by circuit analysis, wherein at least one of input capacitance and input resistance for an input port region is determined by circuit analysis, wherein a maximum resistance error for a rising and falling slope of at least one of said output port region and input port region are calculated to not exceed given threshold values for at least one of said maximum timing error and said maximum slew error.
