For eg: I have an array -
type REG_TYPE is array (0 to FIR_ORDER-1) of signed (DATA_WIDTH+COEFF_WIDTH-1 downto 0)
and another signal X: REG_TYPE.
As per the need of the requirement, i would be calling some adders and multipliers to meet the objective.
And adders have the type of STD_LOGIC_VECTOR.
Upon Portmapping, i have come to a situation where my result(STD_LOGIC_VECTOR) is getting values from REG_TYPE.
This is showing an error. Please provide me guidance
