纯小白，4月开始硬件学习，学校新生培训后端这块一头雾水
运行place_opt时遇到的问题
Error: A Severe error has occurred. To ensure that the script does not continue, the value of sh_continue_on_error has been overridden to be false. Your script is being interrupted. To see the Tcl call stack for the part of your script which generated the Severe error use the error_info command.   (CMD-103)
是哪一部分的脚本出错了

新手不要冲上来直接source现成的脚本。
最好一段一段贴进去，逐条学习吃透。
