Model: Load

Entity Description - Load

The entity description indicates that three parameters are accepted by the load model: nominal power p_nom in Watts, nominal voltage v_nom in Volts, and ramp time t_ramp in seconds. It is not necessary to use all parameters specified in the GENERIC declaration within each architecture of the model.

LIBRARY IEEE;

USE IEEE.ELECTRICAL_SYSTEMS.ALL;

ENTITY load IS

GENERIC(

p_nom: REAL := 1.0;

v_nom: VOLTAGE := 14.0;

t_ramp: REAL := 1.0e-5);

PORT(

TERMINAL p,m : ELECTRICAL;

SIGNAL on_ctrl : IN REAL := 0.0);

END ENTITY load;

The ENTITY description also defines two electrical ports, p and m, for the load model. This declaration requires the use of the ieee.electrical_systems package. A signal port for the control signal on_ctrl of type REAL is also defined.
