- 1. OVERVIEW
-
- This disk demonstrates SCHEMA, a powerful, yet inexpensive
- schematic capture program that lets engineers create
- schematics, wire/net/pin lists, bills of materials and other
- engineering documentation on IBM PCs and compatibles.
-
- This demo disk contains three programs:
-
- 1) A self-running demo of SCHEMA's Schematic and Object
- Editor program, SCHDRAW. This program runs by itself and
- shows many of the capabilities of SCHDRAW.
-
- 2) A demo version of SCHEMA's post-processor, SCHPOST. The
- SCHPOST program does not require any user interaction and
- automatically generates a complete set of post-processor
- outputs from the demo schematic.
-
- 3) An interactive version of SCHEMA's editor program,
- SCHDRAW. If you have a mouse, this program lets you use
- SCHDRAW to create schematics and objects. Read and/or print
- the file SCHDRAW.DOC for more info on the interactive
- version.
-
- The SCHDRAW and SCHPOST programs are demo versions of two of
- the seven programs that comprise SCHEMA. SCHDRAW is
- SCHEMA's schematic and object editor. SCHPOST is SCHEMA's
- post-processor, providing design rule checks, wire/net/pin
- lists, usage reports, and bill of materials extraction from
- SCHDRAW-produced schematic drawings. The standard SCHEMA
- programs that are not provided on this disk are SCHBACK,
- SCHPRINT, SCHPLOT, SCHLIB, and SCHCFG. These programs
- provide PCB layout back annotation, batch printing and
- plotting, object library management, and configuration file
- management functions, respectively. The SCHDRAW version on
- this disk is identical to the actual version, except no
- disk-write or print operations can be done.
-
-
-
- 2. HARDWARE REQUIREMENTS
-
- The following hardware is required to run the demo disk
- programs:
-
- IBM PC/XT/AT or compatible with at least 512K RAM, DOS 2.0
- or above, and one of the following graphics adapter types:
- IBM Standard Color Graphics Adapter, IBM Enhanced Graphics
- Adapter (EGA), Hercules Monochrome, AT&T 6300, Sigma Designs
- Color 400, or Tecmar Graphics Master.
-
- A Microsoft, Mouse Systems, Logitech, or Torrington mouse is
- required to run the interactive version of SCHDRAW.
-
-
-
-
-
- The actual SCHEMA program supports all HP and Houston
- Instrument plotters, in addition to a variety of printers
- including all Epson graphics printers (including the LQ
- series), Toshibas, Star Micronyx, Okidata 192/193, and the
- Apple Imagewriter series. The HP LaserJet+ and Canon LBP-8
- A2 laser printers are also supported.
-
-
-
- 3. RUNNING THE SELF-RUNNING SCHDRAW DEMO
-
- To run the self-running SCHDRAW demo, do the following:
-
- 1) Boot the system normally.
-
- 2) Place the SCHEMA demo disk in drive A and type
- A: (this selects drive A).
-
- 3) Enter one of the following commands, depending
- on the graphics adapter type in your system:
-
- IBMCOLOR (IBM Standard Color, Tecmar
- Graphics Master, Sigma
- Designs Color 400)
-
- IBMENHAN (EGA)
-
- HERCULES (Hercules Monochrome)
-
- AT&T (AT&T 6300)
-
- TECMAR (TECMAR Graphics Master)
-
- SIGMA (Sigma Designs Color 400)
-
- NOTE: The self-running SCHDRAW demo does not support the
- high-resolution capabilities of the AT&T 6300, Tecmar
- Graphics Master and Sigma Designs Color 400 graphics
- adapters. The high-resolution modes of these adapters are
- supported in the interactive demo version only.
-
- After the applicable graphics adapter command is entered, a
- batch file is invoked and the self-running SCHDRAW demo
- program starts. You are asked one question pertaining to
- execution speed. If you have a standard speed PC or XT
- respond with 'A'. If you have a faster PC, such as an AT or
- COMPAQ DeskPro, respond with 'B'. The 'B' response slows
- the program down for use on these faster machines. After
- you have run the program once, you may want to use the 'C'
- response. This takes out the wait times and executes the
- demo at full-speed. The demo program can be paused at any
- time by pressing any key, it continues by again pressing
- any key.

- 4. RUNNING SCHPOST
-
- SCHPOST contains SCHEMA's post-processing programs. SCHPOST
- automatically produces six different outputs, derived from
- an input set of schematic drawings. These six outputs
- include a list of Routing Errors, six Design Rule Checks, a
- Wire List, a Net List (a machine-readable form of the Wire
- List), a Pin List (expanded Net List), two useful Usage
- Reports, and a Bill of Materials (BOM). Additional programs
- are included (at no extra charge) with the actual SCHEMA
- package to convert SCHEMA's Net List output to formats
- required by logic simulation, wire wrap, and PCB layout
- autorouting systems. These include systems from Augat,
- Cadnetix, Calay, Computervision, dataCon, FutureNet, Racal-
- Redac, SCICARDS, SPICE, and Telesis.
-
- A two-page sample schematic (LOGIC.P01 and LOGIC.P02) has
- been included on this disk to let you run the post-
- processor. To run SCHPOST, from DOS enter:
-
- SCHPOST LOGIC A
-
- This invokes the post-processor (SCHPOST), informs it of the
- schematic name (LOGIC), and runs all (A) six 'sub' post-
- processors, each one automatically creating one of the
- outputs discussed above. All readable outputs are sent to
- the screen as SCHPOST executes. Also, a file, LOGIC.NET, is
- created which contains the net list. Use the <CNTRL> <NUM-
- LOCK> keys to control output screen viewing. If desired,
- make a hardcopy of the output by entering:
-
- SCHPOST LOGIC A >PRN
-
- This time, when SCHPOST runs, all output is sent to your
- printer.
-
- NOTE: The Bill of Materials output is 120 columns wide, so
- the appropriate printer mode or wide paper is required.
-
-
-
- 5. RUNNING THE INTERACTIVE SCHDRAW DEMO
-
- The file SCHDRAW.DOC contains additional documentation on
- using the interactive SCHDRAW program. SCHDRAW.DOC should be
- read and/or printed before attempting to use SCHDRAW.
