Question-SI Model in Spectre SI

[twjohn]

Hi all,
I am currently study Spectre SI of Cadence Allegro and found some
problem :
1. How can I build connector model in DML?
2. Some small component such as diodes, transistors, xtals, can not
find model in internet. How do I model them?

Ok, just a few problems here...

It is Allegro PCB SI, but it can use Spectre for the simulator. However
, that is a very advanced situation, usually far beyond someone having
basic library problems.

1. Connector models usually come from manufacturers if you are doing
something specific. Otherwise, the tool will automatically create them
when you build them.

2. If you are using SI, you usually don't do much with diodes,
transistors or crystals, since the tool doesn't simulate them. If you
are using Spectre, then the models for use with that tool are usually
included, and are basically spice models that you can find all over the
place...
