NAME al - Alliance logical format
DESCRIPTION The .al format is the ALLIANCE format for the logical view of a cell. We give below the BNF description of the format : file ::= version header connectors instances transistors signals crosstalk_capacitances end_of_file version ::= 'V ALLIANCE : ' version_number header ::= 'H ' name ',' file_type ',' date /// name : name of the figure /// date : saving file date connectors ::= { connector } connector ::= 'C ' name ',' connector_direction ',' connector_type ',' net_num [list_of_physical_node] list_of_physical_node ::= { ',' node_num } instances ::= { instance connectors } /// An instance is followed by his connectors instance ::= 'I ' model_name ',' instance_name transistors ::= { transistor } transistor ::= 'T' type ',' lenght ',' width ',' drain ',' grid ',' source ',' bulk ',' xs ',' xd ',' ps ',' pd ',' x ',' y [ ',' node_drain ',' node_grid ',' node_source ',' node_bulk ] ',' trname /// drain : number of the net connected to the drain /// grid : number of the net connected to the grid /// source : number of the net connected to the source /// bulk : number of the net connected to the bulk /// xs, xd : To compute respectivly the source and /// drain area /// ps, pd : perimeter of the source and drain /// x, y : coordinate of the transistor in a layout /// node_drain : number of the node connected to the drain /// node_grid : number of the node connected to the grid /// node_source : number of the node connected to the source /// node_bulk : number of the node connected to the bulk signals ::= { signal } signal := sig_index [ { resistance } ] [ { capacitance } ] sig_index ::= 'S ' net_num ',' signal_type [ list_of_signal_name ] list_of_signal_name ::= { ',' signal_name } resistance := 'R ' layer ',' node1 ',' node2 ',' resi ',' capa ',' x ',' y ',' dx ',' dy capacitance := 'Q ' capa /// Each resistance is describe as a resistor beetwen two nodes /// connected to the ground with capacitor with a value of capa/2. /// Capacitance is the entire capacitance of the net to ground. crosstalk_capacitances ::= { crosstalk_capacitance } crosstalk_capacitance ::= K capa ',' sig1 ',' node1 ',' sig2 ',' node2 end_of_file ::= 'EOF' version_number ::= number file_type ::= 'L' date ::= day '/' month '/' year connector_direction ::= 'IN' | 'OUT' | 'INOUT' | 'UNKNOWN' | 'TRISTATE' | 'TRANSCV' /// in : input /// out : output /// inout : input and output /// unknown : no information is available /// tristate : tristate output /// transcv : tristate output and input connector_type ::= 'EXTERNAL' | 'INTERNAL' net_num ::= number node_num ::= number model_name ::= name instance_name ::= name type ::= 'N' | 'P' lenght ::= float width ::= float drain ::= net_num grid ::= net_num source ::= net_num bulk ::= net_num node1 ::= node_num node2 ::= node_num sig1 ::= net_num sig2 ::= net_num xs ::= float xd ::= float ps ::= float pd ::= float x ::= float y ::= float dx ::= float dy ::= float trname :: name layer ::= 'X' | 'PY' | 'A1' | 'A2' | 'CY' | 'CN' | 'CP' | 'CV' | 'CW' | 'CA' | 'RE' signal_type ::= 'EXTERNAL' | 'INTERNAL' capa ::= float resi ::= float signal_name ::= name number ::= { '0' | '1'| '2' | '3' | '4' | '5' | '6' | '7'| '8' | '9' } float ::= number [ '.' number ] name ::= word
