Can anyone tell me what is the use of End Cap cells and Well tap cells in Soc encounter? Where and When do we add these? What is the exact purpose of this?
This is the Custom IC forum concerned with Virtuoso, you need the digital forum.
Endcap cells are used at the end of standard cell rows to create power connections to the power rings or to just end the row properly, usually adding the well extensions for DRC correct designs.
Well tap cells are placed in open spaces in standard cell rows to connect the proper supply to the well.
