Device Model Interface

Hi,

I am a Student and interested in Device Model Interface (DMI) of Analog circuit with C/C++, unfortunately I could only find these two documents

1-PSpice Device and System Modeling in C/C++ and SystemC Tutorial

2-PSpice Device Modeling Interface API Reference

which is very rare to understand DMI and used it with C/C++. Are there any other documents or manuals which explains the basic of the use C/C++ for analog modelling?

Sincerely
