--
-- This module generates pulses with configurable frequency, width and delay.
--
-- In order to generate pulses, the module must be enabled via the en_i port.
-- Once en_i is high, pulses are generated at the frequency specified via
-- freq_i, with the width specified via pwidth_i.
--
-- An optional delay can be added before the start of the pulse, via the delay_i
-- port.
--
-- Note that this delay can be set only before the module is enabled.
--
-- freq_i, pwidth_i and delay_i are given in clk_i cycles.
