I have made a simple 8 pin symbol. There are 4 pins on the left and 4 pins on the right. They are set as "LEFT" and "RIGHT" respectively and "BI" directional.
In the schematic editor when I try to connect the pins on the right of the symbol to a net it won't connect and gives me the red square. It seems like I need to connect the net to the inside of the pins on the right. The pins on the left don't act that way and I connect to a net by clicking on the end of a pin.
However, sometimes it magically seems to make the connection so I feel like I may be doing something wrong here.
