Multinetlabel issues in PCB Layout
443 8
vikramnain20 4 years ago
Hello It would be nice if someone help me on the below issues i am getting in PCB Layout. I have connected multinetlabels in my schematics and when iam doing the layout netlabels are not showed connected to the controller and connected to the netlabels only. just for examlpe-- capacitor c1 & c2 is connected to 3.3vd,gnd & microcontroller on 23 & 146 pin nos. in schematics. But when i layout the PCB found that 23 & 146 pin nos. shown 3.3vd written on it. and c1 & c2 shown connected to 3.3vd & gnd only. Should i connect it to controller pins 23 & 146 also or it will automatically connect it. just chk the image and help me on it. I will appreciate your help.My circuit is connected with multilabels. ![image.png](//image.easyeda.com/pullimage/FWNdMHISbaVgDAnJA1G0ScgCn2xqjGZWg0gMGBGr.png)

"Should i connect it to controller pins 23 & 146 also or it will automatically connect it." It would help if you either make your project public and post the url to it here or at least post a screenshot of your PCB. If you are using the autorouter then nets with the same netlabels will be connected by tracks. If you route the board by hand then you must connect the nets using the Track tool by following the ratlines.

@andyfierman Thanks for your prompt reply & support. PCB layout is not complete and been stuck due to this issue. But schematic is completed.  I made my project as public, plz suggest me on it. Thanks for your support in advance.

@vikramnain20, If you select a pad in your PCB that is connected to a net (for example 3.3vd) and then press the H key, you will see that everything connected to that net will light up. As far as I can tell, the connectivity of your PCB as indicated by the ratlines, is correct to your schematic. You now have to place the components where they need to be and route it.

@andyfierman After placement of the components PCB i checked for DRC and there is no error but nets shows error with cross mark in red color. Is it a error or coz of multinetlabels? Should i proceed with the layout with those netlabel errors.? Thnks for your supprt.
