Re: issues with technology editing in version 7

[Pierce Keating]

Hi Dima,

 

I just sent the signed copies of legalese to Steve, so I plan to start working in 8.05 as soon as I can.

 

With respect to the npn scaling, I wasn't planning to scale the npn transistors because I can't predict what the spice models would be (NPN's vary greatly with different layouts). I have information from AMI that provides SPICE models for a given npn transistor geometry, so I was just going to stick as close to that as possible.

 

Yes, I noticed that I'm stuck with the SUBM rules as well. I started changing them in the existing techology - not sure whether I would pull the plug and start over again. I assume that when I converted the mocmos technology for editiing, if had set the rules to be SCMOS, that the new library would be set to those rules? I guess I'll be starting over again in 8.05, so I'll be sure to check for it then.

 

Yes, I also noticed the "exact" wording in the SCMOS active cut rules as well. The AMI npn layout seens to have non-square cuts, so wasn't sure what I was going to do. Maybe it's safest to make them all square.

 

Thanks very much for your questions.
