This is a *pre-release* BETA version of Scheme. It does *not* contain the code
required to specify pin numbers, object types, part numbers, or
"hidden" nets. Also, Saving, Auto-routing, and plotting are disabled.
Since the Objects are not specified in detail, none of the checking functions
are operative in the demo.
This pre-release version is an example of what we are up to.
If you have questions or suggestions, feel free to call or write us
with them. Our address and phone are in the "info" menu selection
in the sample program.
Gadget tools are provided for:
COPY
DELETE
MOVE
ROTATE (90/180/270)
FLIP (H/V)
GROW
SHRINK
MAGNIFY
REDUCE
PAN (H/V)
SPLIT A WIRE
CHANGE PAGE
MARK ALL
UNMARK ALL
FRAMEWORK LINE TYPE
UNDO
LAYER EDIT
OBJECT/WIRE MODE SWITCH
TEXT INSERTION
The gadgets can be disabled by clicking the right mouse button while the
pointer is over the gadgets. You can still operate, but operations can
only be selected from the menus. Some operations are only available from
the menus in any case.
The object editor is functional, with the exception that
specifying object electrical and physical parameters is disabled. The
object editor can make new objects, or will edit current objects if they
are selected when the editor is invoked by clicking the "grid" gadget.
To use a "new" object, click in the workspace, then select "custom" from
the objects menu.
Scheme has a number of different modes. These are indicated by checkmarks
in the menus, or the drawing in the gadget. These may get out of sync
with each other in this version, but no problems occur because of this.
The "op-amp" symbol indicates "global object-editing", the pencil (which
appears next if the op-amp is clicked, is for text layer editing, and the
drawing outline is for the framework (disabled in this version).
Thge "hand" symbol indicates (in global object-edit) that you are in a
mode that allows manipulation of the objects -- moves and so on. Click on
this gadget, and a wire symbol appears. To wire, click the pointer over a connectable node
on an object, and then again over another object. These wires will
"rubber-band" when the objects are moved in any way.
Multiple connections are permitted.
Mostly, you will have to experiment with the system. If you need help,
you can call us, and we'll try to, but we cannot spend too much time
with each caller or we won't ever finish the project! So be considerate.
We're working on it!
Scheme should be released this summer, but may not actually appear until
September, 1987. We want as many of the "bugs" out as we can manage so you
don't get any "surprises".
Thank you for your time in examining what SoftCircuits has to offer.
Other products under development are in the areas of CAD (surprised?),
Image processing, Amatuer Radio packet handling, and Amatuer Radio
Slow Scan television, as well as some interesting items we can't tell
you about yet.
