Using PowerPro, designers can evaluate power consumption directly on the RTL design rather than going through the time-consuming steps of physical implementation.

The PowerPro RTL Low-Power Platform provides a complete solution to accurately measure, interactively explore and thoroughly optimize power during the RTL development cycle.

Set the objective function value 50X + 40Y = 100 to get the points (0, 2.5) and (2, 0).

It is called no feasible solution if no LP solution is found in the feasible region.

Any (including the optimal) LP solution has to be part of the feasible region.

The feasible region is the intersection of the regions defined by the set of constraints and the coordinate axis (conditions of non-negativity of variables).

This process is repeated with the other restrictions, BLUE and RED regions correspond to the second and third constraint respectively. In the example, this line is the segment connecting A and B points, and the region delimiting this restriction is indicated by the color YELLOW. Beginning with the first, the line obtained by considering the constraint as an equality is drawn.

The following step is to represent the restrictions.

In order to do this, for each variable corresponding to an axis, all variables are set to zero except the variable associated to the studied axis in each constraint.

A numerical scale is marked in axis, appropriate to the values that variables can take according to the problem constraints.

Initially the coordinate system is drawn and each variable is associated to an axis (generally 'x' is associated to the horizontal axis and 'y' to the vertical one), as shown in figure 1.Solve using the Graphical method the following problem: Maximize Z = f(x,y) = 3x + 2y subject to: 2x + y ≤ 18 2x + 3y ≤ 42 3x + y ≤ 24 x ≥ 0, y ≥ 0
