Abstract
In one embodiment, a method of generating write data generates write data for a multi charged particle beam writing apparatus. The method includes dividing a polygonal figure included in design data into a plurality of figure segments including trapezoids each having a pair of parallel opposite sides extending in a first direction, the trapezoids being connected in a second direction orthogonal to the first direction such that adjacent trapezoids share the side extending in the first direction as a common side, and generates the write data including position information of a common vertex of a first trapezoid and a second trapezoid next to the first trapezoid expressed by a displacement in the first and second directions from a position of a common vertex of the second trapezoid and a third trapezoid next to the second trapezoid.
