上面说的是在mask制作时的

"off-grid" is a very "serious" problem, specially for Deep-Sub-Microm process.
It will cause DRC violations and when you make the mask, it will (sometimes) require different grade of mask material and increase your manufacturing cost.

off manufacturing grid ( that is offgrid in calibre drc check ) is a real DRC error ,

should fix ,

since sometimes the offgrid error is not important if it have large space or not result in
shorts or open , but it can results in shorts or open case ,

so please fix it !!!

in icfb :  snap to grid in option before StreamOut

foundry一般留了20%餘量，不會有問題，但是最好還是清掉吧，很簡單花不了多少時間。

drc错误还是需要清理的，除非你和foundry确认

很重要，最好是把OFFGRID 错误清除掉

接触孔还从来没遇到过offgrid额。不过这错得清吧。。除非foundry同意。

  请教， 大侠有没有实际见过由于off grid出问题的情况，如果有问题会出现什么样的问题？
