\subsection{Detailed Description}
Routing Global Cell. 

\hypertarget{classKatabatic_1_1GCell_secGCellDescription}{}\subsection{G\-Cell Description}\label{classKatabatic_1_1GCell_secGCellDescription}
Please note that there are two kind of Global Cells (or \hyperlink{classKatabatic_1_1GCell}{G\-Cell} for short)\-:
\begin{DoxyItemize}
\item The \hyperlink{classKatabatic_1_1GCell}{G\-Cell} used by the global router Knik.
\item The \hyperlink{classKatabatic_1_1GCell}{G\-Cell} used by the detailed router (\hyperlink{namespaceKatabatic}{Katabatic} \& Kite). Although the information they hold is obviously related, they are two separate kind of objects.
\end{DoxyItemize}

The area of the design to be routed is divided in a regular grid of rectangular area, the \hyperlink{classKatabatic_1_1GCellGrid}{G\-Cell\-Grid}. Each rectangular area is a \hyperlink{classKatabatic_1_1GCell}{G\-Cell}.

The \hyperlink{classKatabatic_1_1GCell}{G\-Cell} contains the following informations\-:
\begin{DoxyItemize}
\item The Auto\-Segments that begins or ends in it. The list of segments is not avalaible directly but through the Auto\-Contacts that are owned by the \hyperlink{classKatabatic_1_1GCell}{G\-Cell}.
\item The Auto\-Segments that go straight {\itshape through} it (or {\itshape over} it). Horizontal \& Vertical segments are stored in two separeted list. Those two lists are sorted by layer depth (the deepest layers first).
\item A lot of synthetic information about the density of tracks used in the \hyperlink{classKatabatic_1_1GCell}{G\-Cell}.
\end{DoxyItemize}

Auto\-Contacts are affected to G\-Cells, the area of the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} is the one into which the \hyperlink{classKatabatic_1_1AutoContact}{Auto\-Contact} is allowed to be placed. It is this that way that the respect of the global routing choosen by Knik is enforced. See the \hyperlink{classKatabatic_1_1AutoContact}{Auto\-Contact} constraint box.

When tracks are aligned with the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} boundaries they one exactly on the boundary can belong to the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} on either side of the boundary. But we want a clear and mutually exclusive ownership of each \hyperlink{classKatabatic_1_1GCell}{G\-Cell} area. So, we choose that one \hyperlink{classKatabatic_1_1GCell}{G\-Cell} do not own the topmost and rightmost track. And to implement it, we shrink top and right coordinates by the amount of \hyperlink{classKatabatic_1_1GCell_ac594cb2832ee7ef410c89499258d38fd}{G\-Cell\-::get\-Top\-Right\-Shrink()}, which must be less than the track spacing.\hypertarget{classKatabatic_1_1GCell_secGCellDensity}{}\subsubsection{Saturation \& Density Computation}\label{classKatabatic_1_1GCell_secGCellDensity}
At any depth (i.\-e. layer), in the preferred routing direction, a \hyperlink{classKatabatic_1_1GCell}{G\-Cell} can pass a finite length of wire. For example on an horizontal preferred layer\-: \[ WL_{max} = width(GCell) \times Htracks(GCell) \] Then the density, is the ratio between $WL_{max}$ and the actually used wirelength\-: \[ Wdensity(depth) = \frac{WL_{used}(depth)}{WL_{max}(depth)} \] Normally, the ratio musn't exceed 1.\-0, but the occupied wire length computation, for now, doesn't merge overlapping wires belonging to the same net, so the ratio may be slightly inaccurate. Thus in some pathological cases may be greater than 1.\-0 whithout truly been overloaded.

A Cell is considered as {\itshape saturated} if the overall density is above the saturation ratio given by \hyperlink{classKatabatic_1_1Session_a266a4079ca235e8fdb622ef4996d324d}{Session\-::get\-Saturate\-Ratio()}.

Contact density is calculated as follow\-: \[ Cont_{density} = \frac{|Contacts|}{Htracks \times Vtracks \times 4} \] It is a ratio over the number of actual contacts in the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} and the maximal number. The maximal number being the product of the number of tracks in both direction and 4 stands for the hardwired number of layers (the depth).

Should not be hardwired... {\itshape To be corrected in future versions.}\hypertarget{classKatabatic_1_1GCell_secGCellFeedthrough}{}\subsubsection{Feedthrough Computation}\label{classKatabatic_1_1GCell_secGCellFeedthrough}
The feedtrough value is an estimate is of how many complete tracks have been used on a given layer of the \hyperlink{classKatabatic_1_1GCell}{G\-Cell}. It varies between zero and the number of track on the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} (complete saturation). As an estimate, it doesn't tell you the actual number of free track, but how many you {\itshape may expect} assuming the routing is reasonably well done.

Computation is done as follow\-: \begin{TabularC}{2}
\hline
\rowcolor{lightgray}{\bf Wire type}&{\bf Estimated Cost }\\\cline{1-2}
Straight wire (feedthrough) &{\bfseries 1.\-0} \\\cline{1-2}
Beginning or ending global wire &{\bfseries 0.\-5} \\\cline{1-2}
Local wire. &{\bfseries 1/3} \\\cline{1-2}
Blockage wire &The exact percentage of the track \\\cline{1-2}
\end{TabularC}
\hypertarget{classKatabatic_1_1GCell_secGCellTrackComputation}{}\subsubsection{Track Computation}\label{classKatabatic_1_1GCell_secGCellTrackComputation}
The number of track that can go through a \hyperlink{classKatabatic_1_1GCell}{G\-Cell} in the horizontal direction is computed as follow\-: \[ Htracks = \frac{heigth(GCell)}{Vpitch} + 1 \]

The pitch is assumed to be the same for every layer and is hardwired to 5.\-0 lambda.

This is a bad architectural choice. The informations pertaining to routing should be held at Kite level, not be hardwired and the pitch should be made variable with the layer... {\itshape To be corrected in future versions}.\hypertarget{classKatabatic_1_1GCell_secGCellLazyEvaluation}{}\subsection{G\-Cell Lazy Evaluation}\label{classKatabatic_1_1GCell_secGCellLazyEvaluation}
To save processing time, the densities are not recomputed every time a segment is modified (added, removed or moved). Instead a lazy evaluation mechanism is used. Densities are recomputed each time a density is queried {\itshape and} the lazy evaluation {\itshape not} explicitly disabled (flag No\-Update).\hypertarget{classKatabatic_1_1GCell_secGCellSortingKey}{}\subsection{G\-Cell Sorting Key}\label{classKatabatic_1_1GCell_secGCellSortingKey}
In order to perform a lexicographical sort on the tuple $(density(depth),id)$ of a \hyperlink{classKatabatic_1_1GCell}{G\-Cell}, a specific slave object \hyperlink{classKatabatic_1_1GCell_1_1Key}{G\-Cell\-::\-Key} is introduced. It is the density on one specific depth, not the average density.\hypertarget{classKatabatic_1_1GCell_secGCellDesaturation}{}\subsection{G\-Cell Desaturation / Layer Assignment}\label{classKatabatic_1_1GCell_secGCellDesaturation}
In addition to it's geometrical and density functionality, the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} provides {\itshape desaturation} capabilities. Desaturation is the operation of moving up feedthough \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} from the bottom layers towards the upper ones in order to balance the densities in the different densities. Thoses operations provides building blocks for the layer assignment stage which is provided by the Kabatic tool.

Two strategies are avalaibles, moving one global \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} at a time with \hyperlink{classKatabatic_1_1GCell_a1256c28423a9a260d320e25b3fc1bf57}{G\-Cell\-::step\-Desaturate()} or, when one \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} is moved up, move up the whole net trunk with \hyperlink{classKatabatic_1_1GCell_aab5b30c49b0453db495337931cf284a9}{G\-Cell\-::step\-Net\-Desaturate()}.\hypertarget{classKatabatic_1_1GCell_secGCellImplantation}{}\subsection{G\-Cell Implantation}\label{classKatabatic_1_1GCell_secGCellImplantation}
\hyperlink{classKatabatic_1_1GCell}{G\-Cell} derives from Hurricane\-::\-Extension\-Go to allow a graphical rendering of the routing density.

{\bfseries Returns\-:} {\bfseries true} if an \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} has actually been moved up.

Perform the atomic desaturation, that is move up one \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} from layer {\ttfamily depth} to layer {\ttfamily depth+2}, longuests Auto\-Segments are moved first. Only global feedthrough Auto\-Segments are candidates to be moved up. The Net owning the moved up segment is added to the {\ttfamily global\-Nets} set. If the \hyperlink{classKatabatic_1_1GCell}{G\-Cell} is not saturated on layer {\ttfamily depth}, nothing is done. If the {\ttfamily forced} flag is set, one global \hyperlink{classKatabatic_1_1AutoSegment}{Auto\-Segment} is moved up regardless of the saturation status.
