Sounds like you need to spend a little time reading the IBIS cook book. There is a lot of information in it that will guide you to better understanding of IBIS and its capabilities. A relay consists of two major elements, the coil that provides the force to close the relay and a set of contacts that make the controlled circuit. The coil can be modeled with a Rpower model type. The inductance of the coil is the L of the package, the resistance of the coil is the R and you can add another pin and parallel a clamp diode if needed. The diode clamp would be a terminator model with a powerclamp and just put a short between this dummy pin and the relay's coil model. The relay contacts would be modeled as a series switch model. Series Switches are normally FET switches but if the series resistance is modeled small enough it will look like a mechanical switch. Diodes can be added to nets with terminator models if the diodes are connected to a power or ground node. The diode will just be a power or groundclamp in the model. Sockets and connectors are just connectors. Depending on your target simulator there are several different means of modeling them. The model type you choose will also be dependent on the bandwidth required in your application and if you need to model coupling in the connector or socket. Depending on the resources available to you either SPICE or measurements will get you most of the data for the models along with the information contained in the datasheets for the parts. For the connectors/sockets you might want to add a 3D field solver to your tool kit.

I was asked about IBIS model generation for Relays, Diodes, Sockets and Connectors. 2. Please can you help me about how IBIS models can be generated for above components. Does current IBIS standard supports all the above components. How can Relay characteristics be described in current IBIS models. Also if possible please send an example file. 3. I also read about ICM (IBIS InterConnect Models) models. What are these models. Will the Relay and Socket are considered as connectors. Please do help me in this regard.
