ERmet ZD Single Pair Spice Model and S-Parameter

The ERNI ERmet ZD simulation models are provided in two different formats:
1. Spice compatible models based on L, R, C and K elements in accordance to UC Berkeley Spice3f5 standard.
2. S-parameter data in Touchstone file format

For each format, two different types of simulation models are given:
1. A set of very compact models, which represents only one signal pair (e.g. a-b) of the connector. These models should be used, if only the reflection behavior and the impedance matching of the connector should be analyzed. They do not slow down a simulator significantly.
This modell is available on the ERNI web page.

2. A set of models which represent 3 wafers of the connector with each wafer containing 2, 3 or 4 signal pairs. This model family fully represents the connector behavior including:
- impedance matching
- crosstalk behavior
- ground bounce
This model is only available when the customer has signed an NDA.     

The usage of each model is explained in the header part of the appropriate library file.
