power test measurement windows for the power tests

A65 has power test measurement windows for the power tests such as maxpwr_cpu, maxpwr_cpu_int, maxpwr_l2 and saxpy_simd. Probably they have start and end instruction.

Especially, A saxpy_simd has defined as "LD1 {v27.25},[x2], #8" in document. but after simulation, "LD1 {v27.25},[x2]" doesn't include in log file. 

Is there any way to generate LD1 {v27.25},[x2], #8" in saxpy_simd test? What are the necessary and sufficient conditions of the tests maxpwr_cpu, maxpwr_cpu_int, maxpwr_l2 and saxpy_simd?
