I guess the feature you are looking for is the SNOOPer.

See the chapter "Variable Logging" in the "Training HLL Debugging" from http://www.lauterbach.com/training.html

E.g. if you want to take a log of the variable myvar you can do this like that:

SNOOPer.RESet     
SNOOPer.SELect Var.RANGE(myvar)
SNOOPer.Mode.Changes ON
SNOOPer.Rate 1000.
SNOOPer.Arm

This will periodically read the value of myvar.

Ensure that reading memory is enabled while the CPU is running. You can enable this with command SYStem.MemAccess.CPU (on most CPU architectures) With ARM Cortex CPUs it's SYStem.MemAccess.DAP instead.

To plot the recorded samples use the following command:

SNOOPer.DRAW.Var %DEFault myvar /MarkedVector

If your CPU and debug tool allows the recording of a data trace (e.g. Cortex-M with µTrace or CombiProbe) you can get much better results by using the data trace.
