Misalignment of schematic while porting

garry01

When I am porting schematic library from x foundry to y foundry (for now assume all other instance properties like width length etc are same), there is misalignment so net connectivity is lost.

 For example if i have nmos in x foundry on converting to Y foundry it is getting shifted and rotated. So what is the best possible solution?

I was thinking about shifting and rotating the instances (mos,resistors etc) so that it comes to same position on porting  and then connecting the floating terminals to nearest wire if there is still any offset. Hopefully it should work. If yes then please let me know how to go about it . (i am pretty new to skill).

    Suppose we have a nmos from x foundry library and we want to port it to y foundry, the size of nmos (or the symbolic view) is bigger than nmos of x foundry or for other instances (like egnfets) its smaller. So is there a way that we can do try to make the symbolic view of all such instances (mos,caps,res) in schematics same as x foundry so that we can be sure that shapes are exactly same (though there may be offsets).

    If it is unclear i can post some snapshot.

    Please do let me know.

     

    Thanks
