I have a design that used triangle symbol for ground. I want to change this to the conventional 3-line version of ground (I am going to copy this schematic into another schematic).
However, using CTRL-SPACE to add a ground symbol, then using CTRL_TAB to cycle through the different symbols, does not work. CTRL_SPACE gives me only the triangle, and CTRL_TAB doesn't change it.
It works fine in the other schematic, the one that I want to merge with this older one. It seems that it's something particular to this older file.
I have verified that the $GND_SYMS ground symbol "component" is in the librarary (common), and it does include the correct GND symbol.
Why can't I get the GND symbol using CTRL-TAB?
Have you tried <Tools><Update from Library> and checked the box for 'Ground Symbols'? Logic keeps a local copy of $GND_SYMS within the schematic file so it may not match the one in the library.
Are you sure you don't have '$GND_SYMS' defined in multiple libraries? If not then PADS Logic will use the first one it finds.
