Onderwerp: gEDA-user: blue sky ideas - written down finally


I took the time to document my ideas about heavy vs light symbols and the
pin mapping problem:

http://www.delorie.com/pcb/pin-mapping.html

I got tired of looking it up in the mail archives or referencing it as "some
time in the past...".

If you remember me saying more about these than I wrote down, and can find
it in the mail archives, let me know so I can add to them.

DJ

Good thing to write these ones up, maybe even put them on a wiki page on
gpleda.org so others can join in on the fun and contribute by
adding/extending/correcting/elaborating etc.

On the pin mapping subject I miss an example of the power pins of a
rail-to-rail opamp, just to nail these troublemakers down as well (sometimes
I get Vss hitched to ground instead of the negative voltage rail).

An interesting article about this subject lives here:

http://en.wikipedia.org/wiki/IC_power_supply_pin

The syntax for defining swapable pins and (swapable) gates is something that
one could probably work out quite easily, and feels "natural" to me :)

BTW: there are two D2 pins in your RAM chip example.


On the subject of the database, it's a bazillion parts ot there, only to be
done on a "what-you-need-is-what-you-put-in-the-dbms-first" basis.

This has to be a distributed effort in some way, gedasymbols.org is a good
starting point, it's to big a job for one individual person.

And even for all contributors themselves it's like scratching their own itch
first: 

1) do what is neccessary, 

2) do what is possible, 

And the impossible is done by doing 1) and 2)  :)


Kind regards,

Bert Timmerman.
