Is there an ADXL Library for proteus?

Hey,
I have this project for my final year, i'm makin a segway kind of thing. Before moving onto protype i thought it would be nice if i implement the circuit virtually on proteus but the problem is proteus doesnt have libraries for ADXL320 and Groscope-IDG300.
Can you please suggest me a way to go through thus problem or is there any other simulator which includes such libraries.
I really need help on this. Please reply asap.
