ENDCAP/DECAP/FILLER:
- Endcap is used at the boundary b/w two independent physical blocks. Like end of rows; around the macros. There different types of endcap cells for top, bottom, left, right & for corner.
- De-cap cells are used to provide extra cap to the nearby logic cells. It helps in IR drop issues, by discharging the current to the power rails/strips it is connected.
- Filler cells used for metal continuity and it is added finally after the design is routed.

FILLER : You can provide all size of filler cells, as tool will add filler cells based on available space
ENDCAP: There will be PRE/POST ENDCAP cells in your library. Mention those in PRE/POST cell type
Use verifyEndCap EDI command, to check for ENDCAP related Errors
