Altera JNEye - Manual (Page 46)

• Reserved Parameters:
• The IBIS-AMI reserved parameters are shown. The reserved parameters are meant for the JNEye
simulation configuration.
• IBIS-AMI Rev 5.0 and 6.0 jitter parameters (Tx_Jitter) are extracted and automatically set in the
Transmitter's Jitter/Noise window with the interpretation shown in the following table:
Table 2-9: IBIS-AMI Jitter Parameters
IBIS-AMI Tx_Jitter Parameter JNEye Interpretation
(Tx_Jitter (Usage Info)(Type Float)
(Format Gaussian <mean> <sigma>)) DJ = <mean> UI (pk) or ps (pk).
Uniform distribution
RJ = <sigma> UI (RMS) or ps (RMS)
(Tx_Jitter (Usage Info)(Type Float)
(Format Dual-Dirac <mean> <mean> <sigma>)) DJ = (<mean> + <mean>)/2 UI (pk) or
ps (pk). Dual-Dirac distribution
RJ = <sigma> UI (RMS) or ps (RMS)
(Tx_Jitter (Usage Info)(Type Float)
(Format DjRj < minDj > < maxDj > <sigma>)) DJ = <maxDJ> UI (pk) or ps (pk).
Uniform distribution
RJ = <sigma> UI (RMS) or ps (RMS)
(Tx_Jitter (Usage Info)(Type Integer Float/UI Float)
(Format Table (Labels Row_No Time or UI Probability)
(-5 -5e-12 1e-10)
(-4 -4e-12 3e-7) … )) Refer to the transmitter jitter description
in the Jitter/Noise Component section.
IBIS-AMI Tx_DCD Parameter JNEye Interpretation
(Tx_DCD (Usage Info)(Type Float)
(Format Range <typ> <min> <max>)) DCD = <typ or min or max based on
corner selection> UI (pk) or ps (pk),
