Description

I have a design in the Vivado tool which I want to run a behavioral simulation with different parameters. For this task, I have created some simulation runs with different names as follows:

"sim1 model_PCIe"

"sim2"

"sim3(model_GTX)"

However, when I attempt to run the simulation, the following error appears:

"ERROR: [Common 17-39] 'launch_xsim' failed due to earlier errors"

Why does this occur?

Solution

This is a known issue that occurs in Vivado when a simulation run that contains blank or empty spaces in the name is executed.

In this case, for the run "sim1 model_PCIe"慧族

To avoid this problem, remove the spaces as follows: "前晌弊谨斗sim1_model_PCIe".

This issue is fixed in the Vivado 2013.1 tool.

首先手唤第一步，需要把想要观测的信号标记出来，即mark_debug，有两种mark_debug的方法，我用verilog写了一个简单的流毕手凯水灯程序，只有几行代码，如下：

module main(

inputclk,

inputrst,

output reg [7:0] led

)

(*mark_debug = "薯颤true"*)reg [23:0] counter

always @(posedge clk) begin

if(rst) begin

counter <= 0

led <= 8'b00000001
