A tool for checking and classifying possible errors in a layout to be phase shifted is described. By placing error markers in the layout, a phase shifting engine can be run more quickly and with fewer errors. In some instances, the markers may indicate that a region should be handled on the complementary mask rather than the phase shifting mask to alleviate problems.
