Different Views (symbol, spectre, titan...)

[Dr. von Rosenstein]

Hi,

I'm a little bit confused. I want to simulate some schematics using Spectre. The Cells i used have different Views. Until now i always used the symbol-view. But now i wondering: What are the other views used for? There are these views:


Should i use the spectre-view if i want to simulate using Spectre?

Thank you for all answers!

These different views represent different aspects of the
cell. Some contain connectivity (schematic), some physical
design (layout), some are just netlisting views for other
simulators. spectre view is one of these, tells the netlister
to stop there and call out a model & pins.

You want to have a spectre view for each lowest-level
primitive. But the circuit will still be simulated from the
schematic or config view (depending on whether you
have a need to manipulate in detail, the hierarchy and
alternate simulation views such as veriloga (with an
associated .va code file) or av_analog_extracted (from
layout, with parasitics).

Hm, I'm still confused.
Example: If i want to simulate a simple bridge-rectifier with diode connected transistors. Should i use the symbol-view or the spectre-view for the transistors?
With the symbol-view the rectified voltage is 1.32V, with spectre-view 0.93V.
