Hi, I need to convert this vhdl function in to verilog FUNCTION EXT (A: STD_LOGIC_VECTOR; SIZE: NATURAL) RETURN STD_LOGIC_VECTOR IS VARIABLE RS: STD_LOGIC_VECTOR (SIZE-1 DOWNTO 0); VARIABLE TMP: STD_LOGIC_VECTOR (A'length-1 DOWNTO 0); CONSTANT MSB: natural := min(A'length, SIZE) - 1; BEGIN TMP := TO_X01 (A); RS := (others => '0'); RS(MSB DOWNTO 0) := TMP(MSB DOWNTO 0); RETURN RS; END;

In Verilog you don't need to extend a vector explicitly. The language does it for you. Defining a function for this wouldn't work anyway, since the lengths of parameters and return value must be fixed. Verilog doesn't have unconstrained vectors. Kind regards Marcus
