Abstract
When designing an electronic circuit to be implemented on an integrated circuit die which includes several metal layers, a technology-independent description of a system is generated, the technology-independent description specifying a signal and a selected metal layer for the signal. Also, an electronic circuit description of a system is synthesized from a technology-independent description of the system. Specifically, a technology-independent description of the system is input, the technology-independent description specifying a signal and a metal layer attribute for the signal. Electronic components are selected from a library based on the technology-independent description and interconnections between the electronic components are specified. A metal layer is then specified for an interconnection corresponding to the signal specified in the technology-independent description based on the metal layer attribute specified in the technology-independent description.
