    endcap is placed at right or left most boundary filler cell for isolation of routing .route is not beyond endcap area.it does not allowed to routing come out side beyond endcap.think name itself its defination.

    Add endcap.tcl modified script enable to add a double coloum of tie fillercell (dummy poly gate for isolation) & endcap fller cell at the boundaries of each blockage areas define in the top including boundaries of the top itself.

  • Hello, End Cap cells are typically placed at the end of rows to handle end-of-row well tie-off requirements. If the cells in the library do not have well or substrate ties inside the cells, you are required to tie the NWell to VDD and the substrate to VSS using the FILLTIE cell. Thanks
