BlankIf anybody knows the way to convert SPF to SDF, please advise. Really appreicate.
SPF is Standard Parasitic Format which contains the parasitic RCs extracted from a layout, SDF is Standard Delay Format which contains the delays for cells, and interconnects so this is not a conversion issue but generation issue. You need a timing generator into which you read the netlist, timing libraries, SPF and write SDF from it. You can use any STA for this purpose (Primetime, Pearl etc)
