[SOLVED] dont use attribute problem for libs in icc

Hi

I have synthesized a rtl using lvt and hvt cells.I dumped out netlist and when taking in to pnr tool ,i got errors saying the hvt cells are marked dont use.

so my physical data is not coming.i am unable to change the attribute also,again it is saying they are dont use cells.

remove attribute is also not working.how to fix this issue.

here is the error

why do you think this is a dont_use issue? sounds like a lib is missing.
