missing source signal

Altera_Forum · ‎09-23-2012

I hope somebody could help me and thank you in advance.

My problem is that I face an error message telling me that I not connected the ports, but I did. The message is: Error: Port "da0[31..0]" of type ssd of instance "Int_to_7_seg_disp" is missing source signal

I attached the screen shot here, please help me.

temp is just a single bit, and you're trying to connect a single bit to an entire bus. You need to either create a bus, or connect it to something else.

As another point, you are apparently using unconstrained integer for the seven-segment decoder input. Integer with a range would be reasonable.

Hello, just a question:

I have the same error but all connections are ok, the problem is in connections between the NIOS II parallel port and external BUSes. Is it legal or should I use pins?

Thanks
