Examples on XEM6310

asandjon · April 9, 2020, 10:52am

Hello

i´m not able to run the Example Code provided with the SDK-Frontpanel´s Installation. I´m using the XEM6310 Board. The Verilog Code is okay. I downloaded it to the FPGA through the Frontpanel. But for example, the Addition in the First Example was supposed to be displayed on the Frontpanel, but it doesn´t work.
Can somebody here help me? Sould i add or do something, i till not understand?

Hello asandjon,

Which version of FrontPanel are you using? Were there any errors/critical warnings when you compiled the Verilog? Do the other elements of the First sample work (there should be buttons in the sample XFP file that light LEDs on the board)?

Have you tried using the pre-built sample bitfiles available on Pins?

Hi,

The Buttons to light the LEDs doesn´t work too. the verilog code and the .ucf File are looking like the lines bellow.

Verilog:

default_nettype none timescale 1ns / 1ps

module First(
input wire [4:0] okUH,
output wire [2:0] okHU,
inout wire [31:0] okUHU,
inout wire [3:0] okAA,
input wire sys_clkn,
input wire sys_clkp,

output wire [7:0]   led
);

// Clock
wire sys_clk;

IBUFGDS osc_clk( .O(sys_clk), .I(sys_clkp), .IB(sys_clkn) );

// Target interface bus:
wire okClk;
wire [112:0] okHE;
wire [64:0] okEH;

// Endpoint connections:
wire [31:0] ep00wire;
wire [31:0] ep01wire;
wire [31:0] ep02wire;
wire [31:0] ep20wire;
reg [31:0] ep21wire;

assign led = ~ep00wire[7:0];
assign ep20wire = {32’h0000};
always @(posedge sys_clk) ep21wire <= ep01wire + ep02wire;

// Instantiate the okHost and connect endpoints.
wire [65*2-1:0] okEHx;
okHost okHI(
.okUH(okUH),
.okHU(okHU),
.okUHU(okUHU),
.okAA(okAA),
.okClk(okClk),
.okHE(okHE),
.okEH(okEH)
);

okWireOR # (.N(2)) wireOR (okEH, okEHx);

okWireIn ep00 (.okHE(okHE), .ep_addr(8’h00), .ep_dataout(ep00wire));
okWireIn ep01 (.okHE(okHE), .ep_addr(8’h01), .ep_dataout(ep01wire));
okWireIn ep02 (.okHE(okHE), .ep_addr(8’h02), .ep_dataout(ep02wire));
okWireOut ep20 (.okHE(okHE), .okEH(okEHx[ 065 +: 65 ]), .ep_addr(8’h20), .ep_datain(ep20wire));
okWireOut ep21 (.okHE(okHE), .okEH(okEHx[ 165 +: 65 ]), .ep_addr(8’h21), .ep_datain(ep21wire));

endmodule

Can you confirm that the okLibrary.v and other FrontPanelHDL files are the correct versions for the XEM6310 board that you are using? These files are module-specific. Please also ensure that you have the correct target device selected in ISE (xc6slx45).

If you are still running into issues after confirming these, can you send a support request to [email protected]?
