struct T_LAYER

layer object contains cells and cell connections.

LOCATOR L

general information

char* shellName

The name of the layer shell to use

int LShell

Index refers to the appropriate T_LSHELL object

int nCellTypes

number of different cell types to place in this layer object

LIST* CellNames

Linked list of cell names created during parsing

int* CellTypes

Array of indexes corresponding to the requested cell types; built after parsing

int* CellQty

Array of cell quantities; built after parsing

int nConnect

number of connections between cells

T_CONNECT* CnList

linked list of connectioins created during parsing

T_CONNECT** Connect

Array of pointers to the connections built after parsing to allow for random access

int nRecurrent

number of recurrent connections

T_RECURRENT* recurrentList

linked list of recurrent connections created during parsing

int recurrentHandled

flag to indicate this layer's recurrent connections have been handled (comes into play when a layer is reused in different columns)

Documentation

layer object contains cells and cell connections. Cells are read in as a linked list during parsing. Once all cells are known, The names are looked up. If a name is not defined, there is an error; otherwise, an array of indexes is made which reference the corresponding cell objects. A separete array containing cell quantities is also created after parsing for faster look up.

As for connections, during parsing, they are placed in a linked list. After all connections are known, an array of pointers is made to allow for random access.
