In the design of the PCB, in fact, before the formal wiring, it has to go through a very long step, the following is the main design process:
The PCB manufacturing process begins with a "substrate" made of Glass Epoxy or similar material.
Printed circuit boards (PCBs) appear in almost every electronic device. If there are electronic parts in a certain device, they are also mounted on different sizes of PCB. In addition to fixing various small parts, the main function of the PCB is to provide electrical interconnection of the various parts. As electronic devices become more complex and require more and more parts, PCB wiring and parts are becoming more and more dense. Bare boards (without parts) are often referred to as "printed Wiring Boards (PWB)."

Signal integrity issues can cause problems when you struggle to stabilize the various signals on the board. The IBIS model is an easy way to solve these problems. You can use the IBIS model to extract some important variables for signal integrity calculations and finding solutions for PCB design. The various values you extract from the IBIS model are an integral part of signal integrity design calculations.
