What makes up an IBIS model for a module?
The complete IBIS model for a module consists of several files: 1. The IBIS models of the DRAM used on that particular module 2. The IBIS models of the PLL, registers, and EEPROMs (as needed) 3. The IBIS model of the resistive parallel terminations on the PC 4. The EBD (electronic board description) file of the PCB. This file references the IBIS file of the terminations mentioned above. Together, these files provide a complete representation of the PCB.
