@Matt Venn @jeffdi @Tim Edwards @Dinesh A @Vijayan Krishnan, Is it possible to replace all filler cells with Decap cells and vice-versa? If so, are there scripts that will replace them automatically? Thanks in advance!

@Janani Aravind

set ::env(FILL_INSERTION) 0

by setting this variable will disable filler insertion

Thank you for getting back. In this case, the filler cells would be disabled but will it be replaced with any other cells or will it be empty gaps?

The best method is to set this in the config.tcl for your macro.

Yes, that's how I did. I'm not able to replace the filler spaces with decap cells (seeing errors) but I was able to do the vice-versa. The error with the former case was the "size 13 can not be filled". Thanks

@Janani Aravind I took this from

filler.tcl

filler_placement "$::env(DECAP_CELL) $::env(FILL_CELL)"

So if you set FILL_CELL empty, then only DECAP_CELL used as filler during routing
