the simplest way is by using metal blockage after placement. just use metal blockage(top metal) for entire chip.

you can set the top metal layers.Use "force model routing layer $m <highest/lowest> <layer> -type<signal/power>"

force model routing layer $m highest M5

This will set it for all types of nets.
