11 Design and Construction Software.

Contents of this section

Software to assist in the design and construction of amateur radio related things. Antenna, Circuit Board, Filter, and QSL card design packages are all good candidates for this section.

11.1 Software Oscilloscope

Author

Jeff Tranter, Jeff_Tranter@Mitel.COM

Description

Scope is a simple software emulation of an oscilloscope. It graphically displays voltage as a function of time.

Status

ALPHA. First release.

System requirements

Sound card with input capability supported by the kernel sound driver. SVGALIB is used to do the display work.

Detail

Scope uses the /dev/dsp device to take audio in from the soundcard and displays it on the screen in a manner similar to an oscilloscope. Jeff claims Scope was written more for amusement value than for any serious purpose.

Where and How to obtain it.

You can obtain source, makefile and man page for Scope from:

ftp://sunsite.unc.edu/pub/Linux/apps/circuits/scope-0.1.tar.gz

11.2 irsim

Author

Dmitry Teytelman, dim@leland.stanford.edu

Description

An event-driven logic-level simulator for MOS circuits

Status

Version 8.6, production.

System Requirements

X-Windows.

Detail

irsim is an X11 based simulator for MOS circuits. It has two simulation modes, either switch where each transistor is modeled as a voltage controlled switch, or linear where each transistor is modeled as a resistor in series with a voltage controlled switch, and each node has a capacitance.

Where and How to obtain it.

You can obtain irsim from:

ftp://sunsite.unc.edu/pub/Linux/apps/circuits/irsim.tar.z .

11.3 Spice

Author

University of California, Berkeley, ported by eoahmad@ntuix.ntu.ac.sg

Description

Spice is an analog circuit emulator.

Status

Stable release. Last fortran version produced.

System requirements

Unknown.

Detail

Spice allows you to design and test circuits in a computer modeled environment to see how they will behave without having to touch a soldering iron, or solder.

Where and How to obtain it.

You can obtain version 2g6 of Spice from:

ftp://sunsite.unc.edu/pub/Linux/apps/circuits/spice2g6.tar.z

11.4 svgafft - Spectrum analyser

Author

Andrew Veliath, drewvel@ayrton.eideti.com

Description

svgafft is a spectrum analyser for Linux.

Status

Alpha software, but usable.

System requirements

Linux supported sound card, svgalib, a 486DX33 or better.

Detail

svgafft uses the /dev/dsp device and currently supports 16-bit and 8-bit sample resolution on supported Linux soundcards. It's display is something akin to a high-end spectrum analyzer with falling peaks.

Where and How to obtain it:

Look for svgafft-0.2.tar.gz on sunsite.unc.edu

Licensing/Copyright

Unknown, check any README supplied.
