7.2.3 DSE Assessment Process

The general idea is to make use of the configuration files provided in STORM platform
and that parametrize almost all the possible parameters of the system. As shown in
Fig. 7.5 , a set of parameters are selected to be optimized from the whole number of
possible parameters. In the same sense, a set of metrics is selected for the analysis.
These parameters and metrics are the ones presented in precedent sections of this
study.
The study presented in this chapter compares two optimization procedures that
can be used in order to freeze the design parameters: the traditional semi-automatic
procedure normally used in DS2 and the MULTICUBE optimization flow proposed
in the project. Both approaches will be presented and commented in the following
sections and are based on the common optimization flow that was defined by all the
partners in MULTICUBE (Fig. 7.6 ) as described in Chap. 1.
With this starting point, the optimization procedure has been adapted to DS2
specific context, obtaining the procedure shown in Fig. 7.7 .
