hi, i have know the globle placement based on RePlAce cannot support rotation and flipping, but if i have a cell that is a polygon not a rect. Is it possiple to get a result from Globle Placement?

Is this a standard cell or a macro? We support flipping (not rotation) of standard cells in optimize_mirroring which is part of detailed placement.

I mean a macro, it cannot flipping or rotation

Macro placement is separate from global placement. I don't think it support rotation or flipping but perhaps @mgwoo can comment.

thanks a lot, i don't think so, if i apply the polygon for globle placement, the result may be bad
