IBIS Modeling(4)

An IBIS Block Diagram

• IBIS file contains only a look-up IV/VT data table;
• IV/VT data are extracted from transistor/spice models or measurement;
• IBIS - Behavioral model, for system level simulation;
• No detailed circuit properties/process included in IBIS file;
• Useless for circuit designers;
• Much faster than Spice models in simulation;
• Accuracy......
• Timing/SSN simulation...
