Yesterday ,I designed a 14 filiter using dspbuilder 7.1 with the block of ALTBus,shift taps and Multiplify Adder . I apply two channel sine wave as source , but when I simulate it , the process is failed because the source data's(coming form the sum of the two sine wave) type is double ,conflicting with the ALTBus's tye (I defined it is "signed integer"), what can I do for it ? and how to design the sine wave to signed integer?Thks
You need to use Input and Output blocks to mark the borders of the synthesizable system. The AltBus block now is only used to convert types inside the system.
