Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works. PSDispatch looks fine. Weird.

这个问题看起来是 VirtualBox 组件无法正确实例化 CLSID_VirtualBox with IVirtualBox 这个接口导致的。但是,使用 CLSID_VirtualBox with IUnknown 却可以正常工作。可能的原因是 VirtualBox 计算机控制台组件的问题。建议您检查 VirtualBox 安装是否正确,并确保所有依赖项都已正确安装。同时,您可以尝试重新安装 VirtualBox 计算机控制台组件,或者尝试使用其他版本的 VirtualBox 计算机控制台组件。

module seg_sim; // Inputs reg clk; reg rst_n; reg [17:0] data_in; // Outputs wire [6:0] hex1; wire [6:0] hex2; wire [6:0] hex3; // Instantiate the Unit Under Test (UUT) seg uut ( .clk(clk), .rst_n(rst_n), .data_in(data_in), .hex1(hex1), .hex2(hex2), .hex3(hex3) ); initial begin // Initialize inputs clk = 0; rst_n = 0; data_in = 0; // Wait for 100 ns to allow the reset to finish #100; // Start testing data_in = 123; rst_n = 1; // Clock for 10 clock cycles repeat(10) begin #10 clk = ~clk; end // End of test $finish; end endmodule
这是一个Verilog代码段,其中定义了一个模块seg_sim,包括了时钟信号clk、复位信号rst_n和输入数据data_in,以及三个七段数码管的输出信号hex1、hex2和hex3。同时,该模块实例化了一个名为seg的模块uut,并将输入输出信号连接到uut的对应端口上。
在initial块中,首先将时钟和复位信号初始化为0,将输入数据data_in初始化为0。然后等待100纳秒,以确保复位完成。接着将输入数据data_in设置为123,将复位信号rst_n设置为1,开始进行测试。测试过程中使用了repeat循环,将时钟信号clk取反10次,每次间隔10纳秒。最后调用$finish结束测试。
该代码段可以用于对seg模块进行功能仿真测试,检查其在不同输入数据下是否能正确输出对应的七段数码管控制信号。

这个错误是由于缺少 lombok 依赖库导致的。你可以在项目的 pom.xml 文件中添加以下依赖:
```xml
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.16</version>
<scope>provided</scope>
</dependency>
```
如果你使用的是 Gradle,可以在 build.gradle 文件中添加以下依赖:
```groovy
compileOnly 'org.projectlombok:lombok:1.18.16'
annotationProcessor 'org.projectlombok:lombok:1.18.16'
```
添加完依赖后,重新编译运行项目即可。
