Hello, Abdulrahman , There is a lot of information out there. Some companies have started generating AMS models for I/O cell libraries. My personal favorite books are: * Ashenden et al, The System Designers Guide to VHDL-AMS. This comes with examples for use in educational (free download) version of Mentor's SystemVision. * Fitzpatrick and Miller, Analog Behavioral Modeling with the Verilog-A Language, comes with CD containing examples and software. Information sources include the VHDL and Verilog AMS web sites (http://www.eda.org/), as well as the EDA tool vendor sites (Mentor, Cadence, etc.). Best regards, Lynne "IBIS training when you need it, where you need it."
