Not concrete ones yet that I've heard. If not, is there an argument against it or just that no one has time Time, the avenger. What alternatives do people use? Some pcb action commands can get you a per trace extraction to calculate simple area from, then apply heuristic mapping to lumped param model of the line(s) in other tools. There's pondering of not-existing-yet speedup tools like gsch2cap, pcb2cap that will extract from schematic to gnucap, pcb layout to gnucap based on selection and choice of capacitance model to use. No one's thinking of extracting shapes of trace loops and modeling mutual inductance, if that's what you mean...
