hi: 

There are some problems while learning a .bsf of the quartusII project. 

The main problem is the errors generated when complied the project. 

 

Error: Port "D" of type DFFE of instance "inst1" is missing source signal 

Error: Port "IN1" of type AND2 of instance "inst5" is missing source signal 

Error: Port "IN" of type NOT of instance "inst7" is missing source signal 

 

so,I hope somebody can analyze the .bsf ,the file is as attachment. 

thanks~~!
