GNU Electric sounds really intriguing. To get to know the system I
tried writing a tech file. I ran into some problems that were hard
for me to solve. When I switched from 8.02 to 8.03 things were much
better I decided to start over again and so I started a clean session,
and with the mocmossub library did a
Menu Activated: Edit | Technology Specific | Convert Technology
to Library for Editing...
Menu Activated: File | Save Library
I then quit from that session, started a new session and opened the
library I wrote..
Menu Activated: File | Open Library...
When I opened the library there were 4 errors.
Network: cell 'mocmossub:node-N-Transistor{}' has connections on
port 'generic:[EMAIL PROTECTED]'
Network: cell 'mocmossub:node-N-Transistor{}' has connections on
port 'generic:[EMAIL PROTECTED]'
Network: cell 'mocmossub:node-P-Transistor{}' has connections on
port 'generic:[EMAIL PROTECTED]'
Network: cell 'mocmossub:node-P-Transistor{}' has connections on
port 'generic:[EMAIL PROTECTED]'
These errors can safely be ignored. They stem from the fact that a
technology library has unusual connectivity in it, and the network
analyzer is fooled by it. Specifically, in a node's description, the
ports are connected to each other to indicate connectivity in the
actual node (i.e. the two polysilicon ports are connected to each other).
This is reminiscent of some of the errors that I was getting when I
tried creating my own tech file. However this time I can use this
technology.
Before I proceed to hack up mocmossubX to become my own technology I'd
like to be able to understand the errors and the proper solution. I
blindly went into the jelib file and commented out the port[68] nodes
and arc. I can successfully read the library but when I convert it to
a technology I get
Could not find port p-trans-poly-right in all examples of cell
'node-P-Transistor{}'
Cannot match different examples in cell 'node-P-Transistor{}'
I'm curious what the proper solution is. Hopefully I'll learn a thing
or two.
By removing the error (and removing the connectivity between the
ports and possibly other things) you have actually deleted useful and
important information from the technology library. I will look into
the error messages, but for now, just ignore them.
