Error Message:sdb.M0018:multiple drivers on signal "Net_44", bit(s) "0".

 

I was trying to execute a truth table by using AND and OR gates in the schematic.. But it was showing the above error when I took three inputs for all the gates from the same input ports.. 

 

Can anyone help me on this please

Welcome in the forum, reddy.

Yes of course we can help, but we really need something to work on. Can you please post your complete project, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file. And please name exactly which board you use. CY8CKIT.....

'multiple drivers' mean there are two or more outputs connected together. You should check that.

Yeah but can we not connect two or more outputs as an input to the other Gates??

When you connect two outputs together, one of them being L and the other one H, what value should the input see? How do you prevent burning of your chip in that case?

Or do you mean connect one output to one input, and the other output to a second input? Thats OK, but this will not result in the error you are seeing.
