Suni Lee 版主偷懒哦。我问了两个问题,可你只回答了一个哦。我这两天没有事就试这个stress 分析.开始我在用一个比较复杂的产品分析(是以前做flow+warp分析的)可无论如何都会出错。我以为是我产品有问题,最后做了平板来玩,可还是会出错:
** ERROR 200182 ** Cavity that include node number 1 does not
have any constraints for warpage analysis.
** ERROR 200180 ** One or more unconnected cavities are underconstrained
Check that there are enough constraints assigned
for warpage analysis.
