I am trying to add a custom IP to my EDK project. I am using the Avnet Mini-Module (MM) and EDK 9.1i SP2. This is my first custom IP and I am starting off small. The MM baseboard has three LEDs that I am trying to turn on/off. From my working project I created a custom IP template and then imported my template into my project. I then made the following changes:
To system.ucf I added:
Net fpga_0_LED1_pin LOC =G5 | IOSTANDARD = LVCMOS33; Net fpga_0_LED2_pin LOC =F5 | IOSTANDARD = LVCMOS33; Net fpga_0_LED3_pin LOC =E5 | IOSTANDARD = LVCMOS33;
To system.mhs I added the following:
PORT fpga_0_LED1_pin = fpga_0_LED1, DIR=O PORT fpga_0_LED2_pin = fpga_0_LED2, DIR=O PORT fpga_0_LED3_pin = fpga_0_LED3, DIR=O
and my custom IP
BEGIN opb_test PARAMETER INSTANCE = opb_test_0 PARAMETER HW_VER = 1.00.a PARAMETER C_BASEADDR = 0x73c00000 PARAMETER C_HIGHADDR = 0x73c0ffff BUS_INTERFACE SOPB = opb PORT LED1 = fpga_0_LED1 PORT LED2 = fpga_0_LED2 PORT LED3 = fpga_0_LED3 END
And finally the opb_test.vhd file:
In the entity under user ports I added: LED1 : out std_logic; LED2 : out std_logic; LED3 : out std_logic;
In the architecture I added the following internal signals: signal iLED1 : std_logic := '1'; signal iLED2 : std_logic := '0'; signal iLED3 : std_logic := '0';
An also in the architecture under begin I added:
LED1
