config view
a config view is used to select different views (like schematic, verilog-a, verilog, extracted, ...) of a cell in a schematic and enables you to run simulations for that particular configuration.
It is very useful in the early phase of a design: you start with ideal blocks and as you create the schematics for the sub-blocks you can see the effect of the real blocks compared to the ideal ones.
In the later phase of a design you can substitute the schematics with the extracted views and again see the effect.
