When RTL Compiler do elaborate RTL code, there are a constant value is assigned to the output port. So I get the below error:
Error : Illegal assignment to constant. [CDFG-131] [elaborate]
: An assignment is made to a constant in file 'dena_asic.v'
on line 1712.
: A constant value cannot be the target of an assignment or be connected to an output or an inout port.
How to let RTL Compiler ignore the error and contiune to do elaborate but not quit.
I have tried the two command below, but it does not work.
set_attribute hdl_allow_inout_const_port_connect true /
set_attribute fail_on_error_mesg false /
