f_gen_nrs()

t_slv_arr f_gen_nrs (   start_val in std_logic_vector ,   len in positive ,   step in std_logic_vector "1" ,   step_up in boolean true   )

Function

Create Non-random sequence.

Parameters

start_val	Start value (array will have same data width as start_val)
len	Data array length
step	Increment/decrement between each data word (default 1)
step_up	True (default) for increment, False for decrement

Returns

PRBS sequence in data array

Generate a non-random sequence. The first value is start_val and the value will increment or decrement with the step value for each word.

Example use

array_8bit(0 to 127) := f_gen_nrs(x"00", 128); -- array_8bit is now (x"00", x"01", x"02", ...)
