Setting Time Tolerances & Simulink.sdi.report

I'm trying to figure out how to set the new time tolerance via an API. I looked under the signalObj but that seems to have the relative and absolute tolerances but nothing related to time.

I realized I neglected to add this is under the simulation data inspector when you compare two runs.

Hi Richard,

I understand that there is current no corresponding property in the Simulink SDI API that accesses the time tolerance of a signal for comparison. Such property is accessible in the SDI UI but not programmatically.

We are considering adding a "Time Tolerance" property into our SDI API for R2018a. In the meantime, there is a workaround using Simulink Test to compare a signal with a specified baseline involving time tolerances. In the following documentation:

http://www.mathworks.com/help/sltest/ref/sltest.testmanager.baselinecriteria-class.html

Please scroll down to the example:

"Add Baseline Criteria and Change Tolerance"

On the last line of the example code,

sc(1).AbsTol = 9;

Please change "AbsTol" to either "LaggingTol" or "LeadingTol" depending whether the time tolerance is leading or lagging.

All the best,

David

You write that 'We are considering adding a "Time Tolerance" property into our SDI API for R2018a". What is the outcome of this consideration? Is it already added to 2018a or 2018b? I need this signal time tolerance and I think it is really a missing feature.

In case you haven't seen yet, time tolerance was added in 2018A.
