I've seen mention about 3 years ago about providing an API so that cadence customers can load in psfbin files to a c/fortran/whatever program for additional postprocessing. Did this ever happen? I have a tool which currently works with psfascii, but it would be really nice to not use the ascii version as it gets very big and the parsing overhead is somewhat painful. I have to believe reading psfbin would be much faster. I really don't understand what cadence gains by keeping the format secret and not providing a library to access it. For example, the mathworks documented their .mat files years and years ago and provide libraries now for the new versions. And no, rewriting the tool in skill is simply not an option. It is an in house tool written in c++ originally for use with hspice but now we use it with spectre. Thanks -Dan
