Hi, My design has 5 inputs/outputs and some timing critical nets. When I check connectivity violation after place and route the design by using 45nm technology file (lef file), I got the following error: Database Units: 2000 Design Boundary: (0.0000, 0.0000) (1874.8750, 1850.0700) Error Limit = 1000; Warning Limit = 50 Check all nets Net a: no routing. Net b: no routing. Net s: no routing. Net c: no routing. Net t: no routing. Begin Summary 5 Problem(s) (ENCVFC-98): Net has no global routing and no special routing. 5 total info(s) created. However, when I used another technology file, it works fine without any errors. Is this error because of the metal size and thicknesses? Thank you, Soha
