hii,
i m using , Active HDL 6.3 to write a program for subtractor. compilation is done properly but while cecking in waveform editor . m facin a strange problem . the binary input m giving is not getting celculated properly , the problem would be cleared wid this attached pic .
Hi rockgird, it would be better if you send the code you are compiling. It seems you are not assigning the output correctly.
What are the signals Bi1, Bi2, ... BiN?
Why are they in high impedance state?
The code would be of much help.
