Lattice Ice40 FPGAs

Using internal libraries in VHDL need to look at actual contents of files in install directory, located at ./lscc/iCEcube2.2016.02/vhdl/sb_ice_syn_vital.vhd. This contains the compiler prototypes.

might need to add:

library sb_ice40_components_syn;
use sb_ice40_components_syn.components.all;

in order to get things to work.

Also might need to declare components manually.

Verilog Library description:

SB_RGB_DRV RGB_DRIVER (
.RGBLEDEN(ENABLE_LED),
.RGB0PWM(RGB0),
.RGB1PWM(RGB1),
.RGB2PWM(RGB2),
.RGBPU(led_power_up),
.RGB0(LED0),
.RGB1(LED1),
.RGB2(LED2)
);
defparam RGB_DRIVER.RGB0_CURRENT = "0b111111";
defparam RGB_DRIVER.RGB1_CURRENT = "0b111111";
defparam RGB_DRIVER.RGB2_CURRENT = "0b111111";

VHDL component:

component SB_RGB_DRV is
        generic (
                RGB0_CURRENT : string := "0b000000";
                RGB1_CURRENT : string := "0b000000";
                RGB2_CURRENT : string := "0b000000");
        port (RGBLEDEN, RGBPU, RGB0PWM, RGB1PWM, RGB2PWM: in std_logic;
                RGB0, RGB1, RGB2: out std_logic);
end component;
