Abstract:
A method for processing the Library Exchange Format (LEF) diagram of a layout includes the following steps: Step 1, breaking the LEF diagram into multiple rectangular segments; Step 2, numbering all rectangular segments; and Step 3, combining rectangular segments to obtain a larger rectangular segment and replacing corresponding uncombined rectangular segments with the larger combined rectangular segment. The method reduces the data size of the LEF file and increase the data transmission efficiency of the LEF file.
