The easiest is to create your own .h and .c files for your custom component and include it in your project folder. In those files include system.h so that you can pull your component parameters (address, interrupt id, etc.). Also include io.h so that you can use the IORD and IOWR functions. That way you can write/read directly to your component's registers.

Hi, 

 maybe a sample fits your need.  It is a base implementation of some IO-Reads and IO-Writes for the VIP-Mixer from the Altera VIP-Suite which is wrapped by myself.

Thank you all... 

What are the things to be mentioned in the .h file...I read that _INSTANCE AND _INIT need to be mentioned in .h file. How to define this and the struct?
