XYTOLR — A computer program for integrated circuit mask design checkout

XYTOLR is a computer program which checks integrated circuit mask designs for compliance with design rules such as those which require minimum clearances between diffused and metallized areas. The input is the same machine readable mask description that is used for automatic mask art work generation. Clearance violations, if present, are reported in graphic and printed form with pointers to the erroneous statements in the user's input.
