Greg,
Great suggestion! I added the net labels to the problem busses in my real design and all looks good! Maybe it’s the net names that are the real “connections” Now I’ll have to move on to the layout. I sure appreciate you taking the time to help.

Then when I added a net label to the bus (like you would a wire) everything worked out just fine.. I'm not sure if that is the correct answer, but it cleaned up the errors and the net list showed everything connected correctly.

I am still having difficulty getting a bus to propagate properly from one sheet to another. It is behaving as though the hierarchical connection doesn’t exit. ERC indicates that the buss connection isn’t there and if I generate a netlist, there are no connections! Would someone be willing to take a quick look at the attached project an see if you can again spot the error I am making? In this test case, I am only concerned with the buss. I realize there are other issues that need to be addressed to get a clean ERC.

I’m so embarrassed! That was it. Thanks again for your help.

In addition, I will load up your schematic and try to see what I can see.

The attached files represent a simple test design that illustrate my problem. When I try to connect the two sheets together by drawing a Bus between A_BUS[0,15] on Sheet A to A_BUS[0,15] on Sheet B I get a popup error message “Bad Bus Label”. If I ignore the message and attempt to generate a netlist, I get the same error message.

You used a local label instead of a global label or net name. 2. Somehow numbers were not the last characters in the individual nets or the bus was not the prefix of the net names. 3. Buses in KiCAD are not like computer busses. Only nets with the same prefix followed by numbers are allowed in the bus. A0, A1, A2 in bus A[0..2] is a valid bus but WR, RD, CLK in bus Control is not valid. (I did all of the above starting out) It's difficult to analyze without seeing what you have done. If you email me directly with the archived project files I can load it up and see. Greg _____ From: mmabshaffer <[email protected]> To: [email protected] Sent: Tuesday, June 23, 2009 5:02:04 PM Subject: [kicad-users] Bad Bus Label error message when making netlist I just tried using KiCad for capturing a schematic and all went well until I tried to generate the netlist.. I get a "Bad Bus Label" error popup message for each bus. The design is a hierarchical design with busses going between sheets. Can anyone give me a hint as to what I am doing wrong? ------------------------------------ Please read the Kicad FAQ in the group files section before posting your question.
