To put the bar over the text you have to sum up the width of the used characters. In tragesym there's a lookup table for that task char --> charwidth. > Net names should have the bar over them too, once I get to that > point. > > Also, is there some standard for: > > 1. Where pin numbers get placed Outside, 100 mils away (enough space for negation bubbles) right alignment for left pins, left aligment for right pins > 2. Where pin labels get placed Inside, 50 mils away from the box, left bottom alignment for left pins, right bottom alignment for right pins, center bottom for bottom pins and center top for top pins. > 3. Spacing and text angle for pins on the top/bottom of box-symbols If there are only a few pins on the top, or bottom rotation is IHMO not nesseccary. e.g. ATmega163_DIP.sym For symbols with lots of pins it's useful to rotate labels and attributes: e.g. MSP430x13-4x.sym Please take a look at the invisible attributes too. > I've written a program to extract/insert attributes into .SYM files > (gattrib seems to want whole schematics, not symbols), using open > office's spreadsheet to sort/edit/fill.

It seems there are a lot of symbol generators out there ;-) The tragesym script is part of the utility package. Most of the features are listed here: http://www.h-renrew.de/h/tragesym/tragesym.html For the braves I've attached the script that I use for fixing symbols. Don't use it unless you know what you're doing. The batchfile b is for the workflow only. regards Werner
