Simulink Test Sequence - How to Access Logged Signal Data

I am writing a test using the "Test Sequence" block inside a test harness. The model being tested has a decent amount of logic that generates one signal that is used internally in that model. Due to the nature of the model, it does not need to be an actual output. It has both the "Log Signal Data" and "Test Point" checked on it. I am unsure of how to access that signal inside the "Test Sequence" block.

Hi, are you asking to use Test Sequence block to access some internal signals, such as inside of a subsystem block or a model reference block?

Test Sequence block requires a line to get connect to the signal, which means you cannot access to the signal wireless directly. Or you can use DSMW to write the signal to a DSM block and use DSMR inside of Test Sequence block to read the signal value.

Yeah, that was what I was asking.

Looks like the answer is that the signal either needs to be an output of the model being tested or written to a DSM block and accessed that way.
