gEDA-user: AT90S2313
Hi, I am a geda newbie. I am trying to design a circuit and draw the schematics using gschem. The circuit uses AT90S2313 micro for which the symbol is available under micro. But I cannot see the pin 10, Vdd and pin 20 Vcc on it. Is there any reason for not putting them in there or is there anything I need to do to unhide them? I am sorry for the stupid question. :-( -- Ramakrishnan - VU3RDD ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Is there any reason for not putting them in there or is there anything I need to do to unhide them? I am sorry for the stupid question. :-( I've been working on my first design as well and had a similar question when using the ATMEG64 micro. What I found with many of the IC's I use in the library is that they were created with these pins assigned by default to the Vcc and Vdd nets. Since these pins are assigned by default the author, in an effort to reduce clutter on the symbol, didn't draw these pins and made the net attributes invisible. If you select the symbol, right click and go down into the symbol you can view these attributes. Then press 'e n' (Show invisible) followed by 'v e' (View Extents) you should see that the symbol has net attributes which assign these pins to the power and ground nets. Be sure to go up out of the symbol without saving. Someone else may be able to suggest an easier way to view this information. In my case I wanted to add some decoupling caps to the supply's of these devices so I modified the symbol to include these pins and deleted the default net assignments. Hope this helps, Jeff ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
