In relation to the change scenarios, it is important to stress
that we do not consider the change scenario denoted by the HW release 4. Such
scenario is useful to assess in a qualitative and quantitative way the pluggability of
the design by contract concern . Hence, since the last HW release does not
contain the DbC concern anymore, it does not make sense do quantify the SoC,
coupling, and size of this version. In the following we present the most significant
results for each modularity attribute regarding the other HW change scenarios.
