I need to use an analog delay that has a tolerance so that the delay varies during a Monte Carlo simulation.
TLine would be a great part but it doesn't have a tolerance parameter.
An all-pass network can't be used for the delay because it doesn't have a linear phase response and the signal is complex.
Can TLine or something like it be made to use a tolerance that Monte Carlo can operate on? Any other suggestions?
Yes. Use SuperSpice:-)
SuperSpice allows MC and parameter sweeps on TLines. There are some examples in the example folder.

I don't Monte Carlo, since chip components are ratiometric, requiring different means to test for worst-case.
BUT, couldn't you simply parameterize TD?

I love to cook with wine. Sometimes I even put it in the food.
Yes. Can I used Monte Carlo with a parameterized value? How?

When I was doing this, we were given the process distributions (including tracking) to use in the simulations. We also used end- point distributions to converge on the "worst-case" more quickly. Discretes were another issue though.
