Prevent deletion of certain delay cells in genus ?
I need a module where multiple D-flipflops are connected sequentially and their signal propagation requires a certain delay. I have designed the delay cell and instantiate its modules in the connection where those delay's are need. But when I use this in Genus, due to optimization process, it delete the delay cells(It keeps my Dflipflop cells properly).How could I tell genus not to delete this modules ?
I think turning of optimization may prevent this. Can I do that?
Thanks for your time.

If I use "set_attribute preserve true DLYX" , it only preserve the cells but delete the connections. I want them to be preserved along with the connections.
