\fBGCell\fP \fBGrid\fP\&.
|
|
|
|
The \fBGCell\fP \fBGrid\fP of \fBKatabatic\fP\&. Although the base template class \fBGrid\fP support irregular grid, the \fBGCellGrid\fP is regular, following the Knik global router GCells\&. Only the topmost row and leftmost column may have different height or width to cope with the design real size\&.
|
|
.PP
|
|
Due to the regular nature of the grid, the horizontal & vertical edges capacities are all identical, and initialized from the \fBKatabatic\fP Configuration\&.
|
|
.PP
|
|
The grid is build from the Knik global routing, so obviously a KnikEngine must be attached to the Cell when building the \fBGCellGrid\fP\&. An error is thrown otherwise\&.
