Unable to simulate in modelsim

Hi Krithika,

Is Greenlight Compile part of your project?

Are there any successful simulation before?

Hi,

NO... it is not a part of the project. This is my first project which I need to simulate and check.. the project is just to blink an led so that i'll be familiar with simulation in modelsim 6.4d

can you post the code?

Did you set up the nativelink parameters (ctrl+shift+E -> tab simulation) ?

Hello,

Here is the code. After analysis and synthesis i open modelsim from the quartus tool itself, then all the libraries are complied automatically then i click simulate after that i

m getting error posted above.

module led_gpio(clk,user_led,gpio);

input clk;

output [1:0]user_led;

output [3:0]gpio;

reg [31:0] count = 0;

always @(posedge clk)

begin

count <=count+1;

end

assign user_led[0]= count[22]; //user led 1

assign user_led[1]= count[25]; //user led 2

assign gpio[0] = count[20]; //GPIO9

assign gpio[1] = count[4]; //GPIO1

assign gpio[2] = count[30]; //GPIO2

assign gpio[3] = count[31]; //GPIO10

endmodule

So please suggest if any solutions is there.

Hi,

Nothing looks wrong with the code.

If the Native link setup is done properly when the Modelsim pops up it should automatically run simulation based on your test bench.

Please check your native link setup again.

Thanks,

Hi Karthik,

This is very strange, if command line works but GUI button doesn't.

Have you tried it with a different design? or it happens only with your design.

Another thing since you are using (modelsim version 6.4d designer edition) perhaps you need to contact Mentor and notify them about this issue, they might be aware of it or have any fix for it.

Thanks,

Regards,
