ERROR node $43 cannot be both analog and digital

[laProfe]

I obtain the message:

ERROR node $43 cannot be both analog and digital

I don't known how to find node $43 in my circuit.

When I click ok it gives me the message.

The circuit does not have sources.

Could you help me

[lacy]

To find node 43 you will have to turn on node names. This can be done under the OPTIONS>SHEET PROPERTIES then look for Net Names and click on show all. and them hit the APPLY button at the bottom. This will allow you to see the net names/numbers.

To give a more complete answer for your errors you would have to post your circuit file if that is possible.

Thanks Lacy

I already  try to send my circuit. The system do not let me to send it , because the size is greater than the permitted.

Are , node number and the net name the same?. My sheet preferences already were in -->net names ---> show all.

I reproduce the ERROR node $ground cannot be both analog and digital with another circuit that is smaller.

I don't know how to fix it.

I attach it to this message.

THank you in advance for your attention

Thanks for trying to post your circuit. From the information that I have, net names and nodes numbers are the same. Multisim assigns a net name (usually a number) to each node in the circuit. If you have show all on, it should be showing you the number/name of the nodes.

You could try e-mailing me the circuit at lacy@cwv.net and I will try to find out what is happening.

I found where the error is.
It has to do with buses in circuits with levels of hierarchy.
I attach you 2 new simple circuits which reproduce the error.
P_and2bits_bus_v1.ms10
This circuit  has buses and not levels of hierarchy which works well
P_Sub_and2bits_bus.ms10
The same circuit with 2 levels of hierarchy that does not simulate.
It is very important to me that somebody confirm that it is a problem with the software.

Thanks

I would have to say that based upon what you found that it is a software problem. Nestor or one of the other Team members will have to analyze this and hopefully come up with some sort of fix. I have to tell you that I tried busses within subcircuits using analog components and this did not occur. So it has to be some goofy software error when digital componets are used in this manner. I hope the engineers can analyze this and come up with a quick fix. I think this needs to be resolved as quickly as is possible and a fix issue for it now and not wait until the next version.

I am going to post your circuit that I have modifed. I took out the 2 AND gates in the subcircuit and replaced them with relays. This is just to show that the error only occurs when digital components are used inside subcircuits with busses. Here it is:

That is right.

You probe that when the components inside the subcircuits are analog it simulate well. I have another clue for NESTOR: subcircuits with digital components inside without buses also simulate well.

 The error only occurs when digital components are used inside subcircuits with busses.   I attach 2 new circuits in which I demostrate that when digital components are used inside subcircuits without buses it simulate well.

I am in summer's  vacations evaluating the possibility of using EWB in my next course. I need the problem solved in order to be able to use the software in my course.

Yes, I also have noticed that. I can only hope that they are seriously looking into this. This is a serious defect that needs to dealt with just as quickly as is humanly possible. It kinda defeats the purpose of having busses inside subcircuits if you can't use them they way they were intended to be used.

I have e-mailed Nestor. He has acknowledged receiving the circuits I sent him and he says they are looking into the matter. All we can do now is wait and see what they come up with. I think you and me have done an excellent job of isolating what is causing this error, now it is up to NI to correct it since it is definely software related.

I don't think there is any more we can do except keep after them to issue a fix for this. NI really needs to start issuing some updates because there are a few other problems that need corrected in addition to this one. Even with some of its problems I still consider it the best and easiest simulator out there to use.

Have a Nice Day
