Hi Bestb,

 

Thanks for posting your question. From what I can see, you had a couple of Clearance Errors. To view them better, go to View->Clearances. You'll see blue circles around those pins. If the circles touch each other you'll receive the clearance errors. What you can do is to reset the positions of the pins so that they are not too close to each other. I did it for you and hopefully that clarifies your confusion.

Hi Bestb,

 

Just a quick addition to my first post. There's another alternative to pass the DRC check, that is to change the clearance settings. Go to Edit->Properties->Design Rules->Clearance settings. Decrease the corresponding number to lower the auto error-checking sensitivity. However in the minimum threshold is 0.001mm for the traces so this approach won't make a difference in your case. So please follow my first suggestion or have a look at the new attachment I posted. The version has been changed to 10.0 which you should have no problem opening.

 

For you last question, the connector was not routed correctly becasue of the following two reasons: 1). all the components were placed in the right-bottom corner, therefore there was not enough space for the connector to be routed. 2). you have to consider the width of the trace when routing. Go to Autoroute-> Autoroute/Routing options. Checkmark "Auto Adjust Trace Width" and click OK. Then run the autorouting. You should be able to see all the connections are routed. Please see attached the file of such.

 

Should you have any further questions, please feel free to ask.

 

Have a good day!

Hi Bestb,

 

Can you give more details about your question? Did you mean you used autorouting but some of the nets were not connected?
