    • A flare map calculating method of an embodiment calculates an optical image intensity distribution in each division region set in a pattern region. Furthermore, an average value of the optical image intensity distribution is calculated in each division region. A pattern or plural patterns, which has a pattern density corresponding to the average value, is calculated as a corresponding density pattern in each division region. Furthermore, a density map, which represents a pattern density distribution within the pattern region, is generated based on the corresponding density pattern, and a flare map representing a flare intensity distribution within the pattern region is calculated by convolution integral of the density map and a point spread function.

    • According to one embodiment, evaluation map creating method is disclosed. The method determines number (N) of times on changing division starting position of layout for segmenting the layout into areas M to create the map by segmenting the layout into areas m and obtaining evaluation value v corresponding to area m (P1). The layout is divided by areas M larger than area m by changing the position, centers of k pieces of areas mk among areas m coincide centers of k pieces of areas M among areas M (P2). Pattern densities D of the layout in areas M is obtained (P3). Evaluation values Vk on areas Mk are calculated by convolving pattern density D for each of areas M with distribution function F (P4). The P2-P4 are repeated N times and obtained N pieces of evaluation values Vk are synthesized (P5).
