Abstract
A routing specification is received for nets of an integrated circuit connecting source cells and sink cells in the integrated circuit. A target performance parameter is received for each of the nets, the target performance parameters specifying a propagation property of electrical signals in the nets. Layouts of the nets are generated according to the routing specification. An actual performance parameter for each of the nets in the layouts is generated, in which the actual performance parameters specify a calculated actual propagation property of electrical signals in the nets. A deviation parameter is generated for each of the performance parameters. Each of the deviation parameters is indicative of a degree of deviation of the respective actual performance parameter from its target performance parameter.
