Hello. I am Layout Engineer. And now doing study for DRC, LVS, DFMC and etc. But now new 3 jobs LEF / LDE / LLE.. 1. What is the LEF? I think that is Library Exchange Format. For GDS / OAS format to ASCII format. But some people LEF is Layout abstract for top-level connectivity.. What is different? 2.What is LDE? Use LDE_CHECK. (CDM_CHECK, GDS_CHECK, etc) What is fuul spelling LDE? 3.What is LLE? I think that is Local Layout Effect. and result is STI and WPE option. Thanks for reading. My English is bad.. sry.. but if you help me I really happy today! XD
