求助大神们:铺铜铺好,然后删除多余铜时出现如下问题:program has encounted a problem and must exit, the design will be saved as .sav file that can be recovered using dbdoctor (if applicable), to resolve problem, first obtain the latest software update from cadence support requests.它说用dbdoctor可以恢复,怎么恢复呢?以前遇到了类似的问题,都是笨办法,用备份文件重新来过。求大神指点。{:soso_e100:}
