Symbol generator

The symbol generator is part of the component editor which had been issued with version V18. Please find it in schematic menu Components/Special functions/Symbol-Generator. It eases the creation of symbols with many pins. It supports the creation of symbols with multiple gates (sub-symbols) as well. Each symbol - as soon as created - can be edited later independently from the functions of the generator. The Symbol generator opens in following view:

The pins can be named numerically or alphanumerically (e.g. if you want to name the pins according to the pads of an BGA component like a matrix). In the second case, tick the box at "Alphanumerical (A1, A2... B1...)".

Box "Alphanumerical" (A1, A2... B1...) ticked.

Set the overall number of Pins. This figure should include all sub symbols (gates) if there are such.
Start means the number of the initial pin which not necessarily needs to be 1. Now select the shape a pin shall have: neutral, male, female, ring, dot or box. The little green tick signals the alternative currently chosen .

Whether Pin names shall be visible besides the Pin number can be set by ticking the box accordingly. Whether the symbol shall be surrounded by a rectangular box, set the tick here. The arrangement of pins can happen: left, two sided, alternating (= zigzag) and all around. In general pin number 1 is located top left, while the row continues counter clockwise. If you tick the box "backward" pin 1 starts left in the north while the row continues clockwise.

Symbols means the general number of sub symbols of the component. Which sub symbol you currently see on screen please see in the lower part of the dialog, close to Symbol.

Image: The symbol generator gives e. g. a symbol with 144 pins.

What about the pin names? Please take advantage of editing pin names in a text editor.
