1.3.83. REMOVE_DUPLICATE_REGISTERS
Removes a register if it is identical to another register. If two registers generate the same logic, the second one will be deleted and the first one will be made to fan out to the second one's destinations. Also, if the deleted register has different logic option assignments, they will be ignored. This option is useful if you wish to prevent the Compiler from removing duplicate registers that you have used deliberately. You can do this by setting the option to Off. This option is ignored if it is applied to anything other than an individual register or a design entity containing registers.
