Most or all SPICE simulators that I have used have included .NOISE
analysis and Monte-Carlo analysis, either of which would seem suited to
introducing eye-diagram jitter.=20

Unfortunately, no.  SPICE is a deterministic simulator and does not
simulate stochasic (random) processes.  You will need something like
Agilent ADS, Ansoft Designer, StatEye, or roll-your-own Matlab code to
integrate random noise into your simulations.=20
