 请教楼上,现在就弄了个最简单的文件led_test.v如下,换DEFAULT还是不行
 led_test.v
 
 `timescale 1ns / 1ps
 module led_test (
 sys_clk ,
 rst_n,
 led
 );
 input sys_clk;
 input rst_n;
 output [3:0] led;
 
 reg [31:0] timer;
 reg [3:0] led;
 
 always @(posedge sys_clk or negedge rst_n)
 begin
 if (~rst_n)
 timer <= 0;
 else if (timer == 32'd199_999_999)
 timer <= 0;
 else
 timer <= timer + 1'b1;
 end
 
 always @(posedge sys_clk or negedge rst_n)
 begin
 if (~rst_n)
 led <= 4'b0000;
 else if (timer == 32'd49_999_999)
 led <= 4'b0001;
 else if (timer == 32'd99_999_999)
 led <= 4'b0010;
 else if (timer == 32'd149_999_999)
 led <= 4'b0100;
 else if (timer == 32'd199_999_999)
 led <= 4'b1000;
 end
 endmodule
 先用命令 vlogan -full64 -work DEFAULT  led_test.v ,
 [lq@simuhost simu_test3]$ vlogan -full64 -work DEFAULT led_test.v
 
 Warning-[MXIR-W] VCS-MX build is required
 Please make sure that vlogan is from the intended build.

 上面有个 报警 ?
 
 得到下图
 
   得到上面内容,对吗 ?是不是不太对,work目录里就一个AN.DB文件夹,AN.DB里就是 上图那一堆,
 里面 也没有个啥叫led_test的文件,然后vcs -full64 DEFAULT.led_test,得到错误提示
 [lq@simuhost simu_test3]$ vcs -full64 DEFAULT.led_test
