S parameter convert to lumped RLC

By extracted the channel to S parameter to simulate, but in cadence the simulation time is huge due to the large s parameter file.

Anyone knows some idea that we can convert the s parameter to the lumped RCL circuit to run the simulation?

In order words, if we know a frequency response the the channel( gain/ phase), can we automatically get the equivalent circuits composed of R,L,C and transmission line from that frequency response plot?

The lump circuits does not need to very precisely as the S parameter is.

Thanks.
