gen_vectorial

Description

Vectorial generator:

-Interface: bit or bus
-Configuration: dynamic
-Applications: waveform generator, serial or parallel communication

Examples:

-Included in the own .vhd headfile

Configuration:

-It is necessary to adjust the following type which defines the input size (it affects to area resources):

SUBTYPE valores_vector IS INTEGER RANGE -1 TO nat_synth_65536'high; -- values range for each sample (always from -1)
TYPE vector_integer IS ARRAY (nat_synth_128'high DOWNTO 0) OF valores_vector; -- number of samples*2

where:

SUBTYPE nat_synth_65536 IS NATURAL RANGE 0 TO 65535;
SUBTYPE nat_synth_2048 IS NATURAL RANGE 0 TO 2047;
(...)
SUBTYPE nat_synth_16 IS NATURAL RANGE 0 TO 15;
