gnetlist is the netlist extraction/generation program which is part of gEDA (GPL Electronic Design Automation) toolset. This program takes a schematic for its input and outputs a netlist. gnetlist uses scheme to define the output format. Currently it supports the following backends: 1) Allegro netlist format (-g allegro) 2) BAE netlist format (-g bae) 3) BOM / BOM2 - Bill of Materials (-g bom and -g bom2) 4) Partslist1,2,3 - More Bill of Materials (-g partslist[1-3]) 5) DRC - Start of a design rule checker (-g drc) 6) DRC2 - A second design rule checker (-g drc2) 7) gEDA - native format, mainly used for testing (-g geda) 8) Gossip netlist format (-g gossip) 9) PADS netlist format (-g pads) 10) PCB / PCBboard (-g PCB and -g PCBboard) 11) gsch2pcb backend (-g gsch2pcb) 12) ProtelII netlist format (-g protelII) 13) Spice compatible netlist format (-g spice) 14) Enhanced spice compatible netlist format (-g spice-sdb) 15) Switcap netlist format (-g switcap) 16) Tango netlist format (-g tango) 17) Verilog code (-g verilog) 18) VHDL code (-g vhdl) 19) VIPEC netlist format (-g vipec) 20) Bartels Autoengineer netlist format (-g bae) 21) GOSSIP system simulation system netlist format (-g gossip) 22) MAXASCII netlist format (-g maxascii) 23) VHDL-AMS netlist format (-g vams) 24) Futurenet2 netlist format (-g futurenet2 ) 25) SWITCAP switched capacitor simulator netlist format (-g switcap ) 26) RF Cascade netlist format (-g cascade ) 27) RACAL-REDAC netlist format (-g redac ) 28) PCB actions file for forward annotating pin/pad names from schematic to layout (-g pcbpins) WWW: http://www.geda.seul.org
