Header file for the types and CDL modules for generic utilities

Modules

module hysteresis_switch	(	clock	clk,
		input bit	reset_n,
		input bit	clk_enable,
		input bit	input_value,
		output bit	output_value,
		input bit	filter_period[16],
		input bit	filter_level[16]
	)

Parameters

[in]	clk_enable	Assert to enable the internal clock; this permits I/O switches to easily use a slower clock
[in]	filter_period	Period over which to filter the input - the larger the value, the longer it takes to switch, but the more glitches are removed
[in]	filter_level	Value to exceed to switch output levels - the larger the value, the larger the hysteresis; must be less than filter_period
