Appendix B
HSPICE and HyperLynx/Eldo
Correlation Results
Introduction
The results generated by the HyperLynx and Eldo simulators are validated by executing a
set of the same simulations in both simulators and plotting the waveform results on top of
each other to verify identical outcomes.
Note:
HSPICE version A-2009.03 was used for the S-parameter/circuit correlation and the GTP
REFCLK and GTP transceiver simulations.
For this correlation, only the silicon models for the GTP transmitter and receiver are used.
Package and channel models are not used, except for the GTP reference clock, where the
package model is included.
Table B-1 lists the parameter settings used by the GTP transceiver simulations.
