IPC naming convention for schematic symbols?

IPC does not have a standard naming convention for schematic symbols.

I would recommend that every schematic symbol be named -

ComponentManufacturerName_MfrLogicalPartNumber

Example of a Texas Instruments schematic symbol Name:

TI_SN74GTLPH32912ZKFR

This way every schematic symbol has a unique name. There are almost 50 million devices with Logical Part Numbers assigned by each manufacturer. Therefore there are 50 million different schematic symbols.

I would also store each schematic symbol in a component manufacturer library. i.e.: If I use 100 different manufacturers I would have 100 different libraries. This makes it easy to maintain and easy to locate parts.

I have written up 2 schematic symbol naming conventions for different companies. It is quite the challenge, because you will never cover everything. What we wanted was a unique method to describe each schematic symbol, so when you place it within the schematic editor you know what part is used. When you place a part in the schematics you will need to know the very least the most important parameters of the part you pick. There is just no way you place a 1uF cap and be done with it. How do you know if it is a SMT or THT component? 1206 or 0805, maybe 0402. Is it being used in a commercial environment or maybe in a military environment? What the temperature range of the cap?

The most elegant solution so far is I have used is a database library, that contains all parameters and a link to symbol, footprint and datasheet. This is very convenient for the end user to work with. It was a simple pick and place. And no editing parts once they were placed in the schematics.
