I am designing a 4 bit ripple adder using input and output buses. They are named A[3..0],B[3..0] and Sum[3..0]. When I try to simulate the circuit though I get these errors:
Warning: Wrong node type and/or width for node "|AdderRipple|A" in vector source file. Node in design is of type Bus and of width 4, but node in vector source file is of type 9-Level and of width 1.
Error: Can't simulate mismatched node types
Warning: Wrong node type and/or width for node "|AdderRipple|B" in vector source file. Node in design is of type Bus and of width 4, but node in vector source file is of type 9-Level and of width 1.
Error: Can't simulate mismatched node types
Warning: Wrong node type and/or width for node "|AdderRipple|Sum" in vector source file. Node in design is of type Bus and of width 4, but node in vector source file is of type 9-Level and of width 1.
Error: Can't simulate mismatched node types
Error: Quartus II Simulator was unsuccessful. 3 errors, 3 warnings
What am I doing wrong here?

Hi,
how did you define your inputs in the vector file ? I assume you have a small test project.
Can you post it in the forum ?
Kind regards
