MATLAB调用nclaunch启动Xcelium模拟器报extra characters after close-quote错误

错误extra characters after close-quote源于hdlsimmatlab命令的-input参数中存在嵌套双引号，导致Shell解析时提前闭合外层引号，使Tcl无法正确处理后续命令。例如原代码中-input "{@force clk_enable {"1"} -after 0ns}"这类语句，内层的"1"会被Shell误判为外层引号的闭合标记，剩余字符因此变成无效内容。

解决方案 #

将Tcl命令中包裹值的双引号替换为大括号{}（Tcl中可用大括号实现分组，无需嵌套引号即可正确传递值），同时将原代码中的HTML实体"替换为实际双引号。此外，移除simvision命令中不必要的反斜转义（如\[、\$w），确保Tcl能正确执行变量替换和命令调用。

修正后的代码 #
