Hi, Modelsim meldet bei folgendem cod den feler:Case statement covers only 4 out of 81 cases. Aber warum? Bei 2 bit gibt es nur 4 Möglichkeiten und nicht 86! CASE instruction_register( 15 DOWNTO 14 ) is when "00" => linear_address <= DPP0(3 downto 0)&(instruction_register( 13 DOWNTO 0 )); when "01" => linear_address <= DPP1(3 downto 0)&(instruction_register( 13 DOWNTO 0 )); when "10" => linear_address <= DPP2(3 downto 0)&(instruction_register( 13 DOWNTO 0 )); when "11" => linear_address <= DPP3(3 downto 0)&(instruction_register( 13 DOWNTO 0 )); end case;
