Acceleration, Contour, Fabric, Field, Foliation
Learn to identify and interpret key trace analysis patterns including trace acceleration, contour, fabric, field, and foliation. This lesson helps you understand how to analyze sequences, differentiate trace components, and apply mathematical analogies to software trace diagnostics.
We'll cover the following...
Trace acceleration
Sometimes we have a sequence of activity regions with increasing values of statement current as depicted in the following figure:
The boundaries of regions may be blurry and arbitrarily drawn. Nevertheless, statement current is visibly increasing or decreasing, giving this pattern the name trace acceleration from analogy with physical acceleration, a second-order derivative. We can also metaphorically use here the notion of a partial derivative for trace Statement Current and Acceleration for ...
