Expected vs measured signal comparison

Compare two CSV signal columns with a time shift, interpolation, and absolute plus relative tolerances. Export every verdict.

State the comparison rule.

The file contains both traces on one increasing timestamp column. The expected trace is sampled at the shifted time using hold or linear interpolation; the actual trace stays at the recorded samples. Points outside the common time range are excluded and counted. Relative tolerance is based on the aligned expected value. A zero expected value therefore uses only the absolute tolerance.

Allowed error = absolute tolerance + |expected| × relative tolerance / 100 PASS when |actual − aligned expected| ≤ allowed error
