HI , I am trying to generate LEF file of an abstract (top level cell: TOP_CELL). Eventhough LEF is getting generated it is missing the following information. ################################################### CLASS; Symmetry ; SIZE X Y; FOREIGN TOP_CELL_NAME (0 0) N ORIGIN (0 0); ####################################### I am using LEF Version: 5.7 Virtuoso: IC6.1.7-64b.500.7 options enabled in LEF generation menu window are 1) LEF File Name: TOP_CELL.lef 2)cells 3)Output cell(s): TOP_CELL 4)Output views : abstract 5) Lef version: 5.7 6)No Technology 7)Generate cell list by: Cells in Design 8)Use GUI Fields Is there anything wrong in the way LEF is being generated ?. I am seeing the pin information and blockage layer information available in the LEF file that was generated. Regards Anand
