VHDL error at <design>.vhd(): value cannot be assigned to constant "<constant name>" - VHDL error at <design>.vhd(): value cannot be assigned to constant "<constant name>" Description This error may occur when you assign values to specific bits of a generic. For example, this error can occur if you have the following declaration and then assign specific bits within a generic construct, as shown below. generic( reset_value : std_logic_vector(15 downto 0) ... generic map( reset_value(2) => '1', reset_value(7) => '1', reset_value(9) => '1', ... The Quartus II software does not allow specific bits of a generic construct to be assigned. Instead, you must assign the entire generic construct, as shown in the following change to the generic map from the example above: reset_value => "0000001010000100", This problem is fixed beginning with the Quartus II software version 8.0. Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['novalue'] novalue novalue ['Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
