Technology File Rules for Floorplanning Tools

The Floorplanning tools require the following rules in the technology file to work correctly:

• minSpacing required for all the valid layers and layer purpose pairs.
• minWidth for all the valid layers.
• minVoltageSpacing for all valid layer purpose pairs.
• Grid information for all the routing metal layers for creating placement and routing grids.
• mfgGridResolution for creating manufacturing grid.
• Preferred routing direction for all the metal layer.
• Site definition for creating I/O rows.
• Standard and custom via defs and standard via variants defined in the technology file to define the spacing type.
• minEnclosure(minExtensionDistance) and minOppExtension between the via layer and cut layer to define the spacing type.
• Routing grid information from technology file for pin snapping.
• Placement grid information for instance snapping.
• All valid layers defined in the technology file.
