IBIS Models Support in Eldo<br />

Example 4—Simultaneous Switching Output Noise<br />

Specifies voltage/time plots of the voltages at both pin 5 and 6 of the IBIS component.<br />

Simulation Results<br />

Figure 17-21. Package Parasitics Cross Talk<br />

There is both capacitive and inductive coupling between pins 5 and 6. This coupling results in a<br />

ringing effect on pin 6.<br />

Example 4—Simultaneous Switching Output Noise<br />

Netlist file: sson.cir<br />

IBIS file: tx_rx_pm.ibs<br />

This example deals with the simulation simultaneous switching output noise (SSON). The [Pin<br />

Mapping] keyword in the IBIS file contains information on how power supplies are connected<br />

to individual buffers or groups of buffers; it can be used for predicting SSON.<br />
