< p > This tutorial is aimed at two goals :< / p >
< ul class = "simple" >
< li > Presenting how to use Python scripts to control < span class = "sc" > Coriolis< / span > .< / li >
< li > Make a basic introduction about the < span class = "sc" > Hurricane< / span > database and its
concepts.< / li >
< / ul >
< p > While this tutorial is aimed at presenting the < span class = "sc" > Hurricane< / span > database,
do not feel limited by it. You can use < span class = "sc" > Hurricane< / span > objects as attributes
of < span class = "sc" > Python< / span > objects or use < span class = "sc" > Python< / span > containers to store them.
The only limitation is that you may not use < span class = "sc" > Hurricane< / span > classes as base
classes in < span class = "sc" > Python< / span > .< / p >

< h3 > 1.1 Terminology< / h3 >
< p > In the < span class = "sc" > Hurricane< / span > database, the < em > logical< / em > (netlist) and < em > physical< / em > (layout)
views are fused. As the main goal of the database is to support place & route
tools, we usually starts with a < em > pure< / em > netlist which is progessively enriched
to become a layout. Cell, in particular, is able to be in any intermediate
state. Many of our objects have self-explanatory names, but some
don't. Thus we summarize below the more important ones:< / p >

< h3 > 1.2 Generalities< / h3 >
< p > The C++ API has been exported in Python as closely as possible. Meaning
that, save for a slight change in syntax, any code written in < span class = "sc" > Python< / span >
could be easily transformed into C++ code. There is no specific documentation
written for the < span class = "sc" > Python< / span > interface, you may directly use the C++ one.< / p >
< p > Mostly:< / p >
< ul class = "simple" >
< li > C++ namespaces are exported as < span class = "sc" > Python< / span > modules.< / li >
< li > The < em > scope resolution operator< / em > < span class = "fboxtt" > ::< / span > converts into < span class = "fboxtt" > .< / span > .< / li >
< li > C++ blocks (between braces < span class = "fboxtt" > {}< / span > ) are replaced by indentations.< / li >
< li > In C++, names are managed through a dedicated < tt class = "docutils literal" > Name< / tt > class.
It has not been exported to the < span class = "sc" > Python< / span > interface, you only have
to use < tt class = "docutils literal" > string< / tt > .< / li >
< li > Coordinates are expressed in < tt class = "docutils literal" > DbU< / tt > which are < tt class = "docutils literal" > long< / tt > with a special
semantic (see ??).< / li >
