EPC V19.0.6: Having problems creating a sch component for the TBD62064AFG.
When it comes to pinning this IC is something of an oddball as it skips pin numbers and even has a good number of NC pins. And to top it all off some of these NC and missing pin number fall inbetween the I/O pins that is needed on the sch symbol.
For a sch symbol it is not allowed to skip pin numbers, and there is no way to hide the excess pins either.
You can connect central GND pins (=>pins 17 & 18) (and 2 COMMON pins) together in the Component Editor (using commas) and add copper heatsink area "under" the component in Symbol Editor for the Fins.
Yes I know about the comma but I dont see how it would help in this case. The main problem here is the 6 NC pins, and I dont want these to show in the sch component. The only pins on the sch component should be the 8 I/O pins, and 1 or 2 of each COM and GND. The numbers of the NC pins falls inbetween the I/O pins.
If there was a way of totally hiding those NC pins and their name and number the problem would be solved
You cannot miss out a pad in the schematic, so goto design Tech => Pads and create a new Terminal2 with 1 thou "round" characteristics. Edit the Component symbol such that the pins you do not want visible to have Terminal2 properties. Then you can delete Pin Number and Pin Name in schematic Editor. So you then only have a tiny (invisible) 1 thou dot instead of the default 60 thou cross as a pad.
Edit. Appears you can have even have a "0" size which would be invisible! (I assumed it would need a actual size >0 !)
Havent tried zero size, but used 0.001mm. Its invisible but wires can still be connected to it if one hits the right spot. I placed it well inside the symbol where there are no terminals so its not a problem.
Skipping sch pin numbers ??
