3 ==============================
9 When designing a printed circuit board (PCB) it's often desirable to
10 create a 'schematic' which shows the components to be used and their
11 connectivity in an abstract fashion. The connectivity information is
12 then used to help when designing the actual circuit board.
14 ``gsch2pcb`` is a command-line tool, part of the gEDA suite, which is used
15 to generate and update a PCB layout. It works with schematics created
16 by ``gschem``, part of the gEDA suite, and layouts created by ``pcb``, a
17 PCB layout system commonly used with gEDA.
19 ``xgsch2pcb`` provides an intuitive, user-friendly graphical interface to
26 ``xgsch2pcb`` requires:
30 * python-gobject (if using python-gtk2 >= 2.10)
32 * A recent version of the gEDA suite
33 * A version of ``pcb`` compiled with D-Bus support.
36 * python-gnome2 (For launching the about URL)
38 Building ``xgsch2pcb`` from source code additionally requires:
47 If you have fetched the sources from the git repository you will need to
48 create the necessary autoconf files. To do this, change into the source
49 directory and execute the command:
53 This generates a ./configure script amongst other things, which you can run
54 to configure the software.
56 As long as you have all the dependencies installed:
58 ./configure && make install
66 The main window is divided into three main areas:
68 * The toolbar at the top offers the usual options to quit the
69 program and to load and save project files.
71 * The left hand 'Schematic' frame shows a list of schematic pages that
72 the PCB layout will be based on. The 'Edit schematic' and 'Edit
73 attributes' buttons respectively launch ``gschem`` and ``gattrib`` to
74 edit the selected schematic page.
76 * The right hand 'Layout' pane shows the name of the PCB layout file
77 associated with the project. The 'Edit layout' button launches
78 ``pcb`` to edit a file, and will offer to update your PCB layout if
79 necessary. The 'Update layout' button forces an update of the PCB
80 layout even if one isn't strictly necessary.
82 The update process will carry out the following actions to modify your
83 layout, after launching ``pcb`` if isn't already running:
85 1. Remove any elements from the layout that are not in the schematic.
87 2. Find any elements that are in the schematic but not in the layout,
88 and add them to the layout (in the top left corner). N.b. that it's
89 probably a good idea to leave this corner of your layout clear
90 until the layout is more or less finalised, to avoid new elements
91 interfering with elements which have already been placed and
94 3. Clear your rats and load a new rats nest.
96 4. Update the component pin names to match the pin names on the
99 Note that the update process won't modify your PCB file on disk, and
100 will take into account any changes you have made since you last
