I have an IBIS file from a vendor. How can I use this with Micro-Cap?
The IBIS files can be used in conjunction with the IBIS components found under the Analog Primitives \ IBIS group in the Component menu. A guide on using these components can be found in the Winter 2008 issue in our Newsletter section.
A common misconception of many users that we have talked to is that they expect the IBIS model to simulate the actual device. IBIS models do not model the internal logic of the device. They only simulate the I/O buffer structure. For simulation of the actual device, a SPICE model needs to be used instead. The typical IBIS file contains the current and voltage characteristics, package parasitics, and protection device characteristics of the I/O buffer structures.
