Hi, I do not know why I'm getting port errors running LVS. I labeled them like label port_name and the label was properly attached to the metal. I have them on the extracted netlist also but I get port errors. Netlists match uniquely with port errors.

We are getting the same thing.. Magic seems to be extracting internal labels (which haven't been made into ports on purpose) as ports and bringing them up through the entire hierachy to the top level, and failing on port matching. One is associated with a Deep N Well, but it appears to have picked another net seemingly randomly..

@Amirhossein zanjani: After making a label, you need to do

port make <index>

. If you use the GUI (Edit ---> Text) to create the label, then you can make it a port just by checking the "port" checkbox, and you can force it to be attached to a specific layer.

@Amirhossein zanjani does @Tim Edwards’s suggestion solve the problem?

@Mitch Bailey Yes, thank you @Tim Edwards The port error was because of the port order mismatch, I ran port index <index_nr> and it worked
