Library

Activate/Dynamical

Description

This block implements an accumulator with the option to reset the state. The block can be configured with or without direct feedthrough. If direct feedthrough is selected, the current value of the accumulator is copied on the output synchronously when the block is activated. Otherwise, the previous value is copied. When the clk port is activated, dX is added to the internal state. When the reset port is activated, the internal state is set to X0. If both the reset and the clock are activated, priority can be given to one or the other through the last parameter.
