I have an RTL , how do i encrypt it? Will the encrypted RTL be synopsys tool friendly, because i want to give it to a customer who uses this encrypted RTL source and synthesis with Design compiler . This is a common concern

Synopsys provides an utility named "synenc"

how to encrypt using this utility?

In the unix prompt, say

path of the synopsys area/syn/bin/synenc rtl.v

how to read this encrypted rtl in DC

dc_shell-t> read_verilog rtl.v.e
