Dai,
It is up to EDA tool how to apply these parameters. In bit-by-bit simulation,
Tx_Jitter and DCD affect the input signal. In statistical analysis, Tx
jitter/DCD should be included into the main algorithm: post-processing with
Tx_Jitter or DCD could be inaccurate. Only Rx jitter can be added later by
convolution.

Greg. The jitters and noise are applied by EDA tools post-simulation.
Thanks,

Subject: [ibis-macro] Tx_Jitter and Tx_DCD
I have a basic question about where Tx_Jitter and Tx_DCD are supposed to be
applied during simulation:
Is the EDA tool supposed to apply Tx_Jitter and Tx_DCD, or is that up to the
algorithmic model?
I was unable to find the answer in the following sections of IBIS 5.1. Maybe
it's in another section that I missed.
Section 10.2.3.2, Time Domain Simulation Reference Flow, page 161
Section 10.2.2, Time Domain Simulations, page 160
Section 10A, Reserved Parameters Reference, page 187
