How to import outside model files and how to use *.sp file in ADS?

Hi,

I have my own model for analogue devices and *.sp file which I spent it on simulating for H-Spice software. Now, I want to reuse it to run simulation for my schematic in ADS2008.

Please kindly let me know how to import outside model files into ADS and how to use *sp file to simulate in ADS?

Thanks and regards,
