<h1>Constraint Modeling</h1>
<p> The <b>Constraint</b> page is your starting point for any constraint modeling activity. Some patterns are provided to facilitate the definition of constraints.
Below, we give an overview of the constraint patterns available so far:
<ul>
<li>Allocation;</li>
<li>Function Coupling;</li>
<li>Safety Level;</li>
<li>Memory Utilization.</li>
</ul>
<h1>Deployment Synthesis</h1>
<p> The <b>deployment synthesis</b> enables to explore the allocation of tasks to execution
units w.r.t. to the constraints and objectives described on this page.
</p>
<h2>Allocation</h2>
<h2>Constraints</h2>
<h3>Allocation</h3>

By selecting a task in the table on the left, and a (HW) execution unit on the right you can add an allocation or dislocation constraint.

<h2>Safety Level</h2>
<h3>Memory Utilization</h3>
<img src="pictures/Memory.png", width = "100%"/>
<p>
In the <b>Memory Utilization</b> Pattern you are allowed to specify (as a percentage value) the amount of memory that can be used by tasks allocated to a given execution unit. In order to do so, just modify the values in the last column of the table. In the figure above, e.g., we are specifying that the tasks allocated to <i>Core01</i> can only use 50% of its memory.
As you can notice from the figure, in the DSE Navigator on the left the constraints just defined appear listed as Target Definition steps.
</p>
<h3>Safety Level</h3>
<img src="pictures/Safety.png", width = "100%"/>
<p>
In the <b>Safety Level</b> Pattern you are allowed to specify the allocated safety level of each HW execution unit by modifying the values in the table. E.g., if you specify that <i>Core03</i> must be lower than SIL2, a constraint is created that forces all tasks deployed into <i>Core03</i> to have a safety level lower than SIL2.

<h2>Memory Utilization</h2>

<h3>Hardware Optimization</h3>

In the <b>Memory Utilization</b> Pattern you are allowed to specify (as a percentage value) the amount of memory that can be used by tasks allocated to a given execution unit. In order to do so, just modify the values in the last column of the table. In the figure above, e.g., we are specifying that the tasks allocated to <i>Core01</i> can only use 50% of its memory.
As you can notice from the figure, in the DSE Navigator on the left the constraints just defined appear listed as Target Definition steps.
This pattern allows you to create optimization objectives for the hardware components (table on the left) where the tasks (table on the right) are running.
The optimization function consists of two main parts:
<ul>
<li>Optimization Direction: it can be either minimization or maximization of the function;</li>
<li>Aggregation Operator: it can be either a <i>sum</i> over hw properties (e.g. the sum of the hardware costs) or <i>count</i>. The count function basically just counts the number of model elements (ECUs in this case) in an architecture.</li>
</ul>
When you are done, you can press the button <i>Add</i> to create the objective.
</p>
<h3>Bus Bandwidth Optimization</h3>
<img src="pictures/BusOptimization.png", width = "100%"/>
<p>
This pattern allows you to <b>optimize the bandwidth</b>
of a given transmission channel. You should first select the transmission unit you
want to consider from the menu (in the figure above, <i>InterdomainFlexRayBus</i>
is selected) and then select the optimization direction via the option button (either
<i>minimize</i> or <i>maximize</i>). Finally press the button <i>Add</i> to create
the objective.

<p>
Constraints that define the admissible solution space, or objectives that rate the quality
of solutions are defined before performing the actual synthesis. The pattern-based
editors to define constraints and objectives can be reached using the b>Constraints</b>
button of the DSE dashboard.
