Electrics (V1.1) Digital Designer
---------------------------------
Electrics is a group of programs for designing and simulating digital
electronic circuits on the Amiga computer. The circuit to be tested is
drawn using simple and complex gates. Multiple logic levels and drive
strengths permit realistic circuit behavior during simulation.
SCHEMATIC PROGRAM:
A circuit design is drawn using Wire, Label, Text, and Symbol objects.
Symbol objects are obtained from a library of simple gates (NAND, XOR,
etc.) and complex TTL gates (74193, 74245, etc.). The circuit design may
contain one sheet, or span up to 99 sheets.
SIMULATOR PROGRAM:
The circuit design is simulated by applying signal levels, and evaluating
the results. The sequence of signal levels to apply is described in an
ARexx script. Signal levels may be '0' (low), '1' (high), 'X' (unknown),
or 'Z' (floating). The activity of the signals may be observed by
connecting various viewing programs to the Simulator. Original signals
may be renamed, used to create new ones, or grouped to create signal
Buses.
VIEWER PROGRAM:
The Viewer may be connected to the Simulator in order to record signal
activity during simulation. This activity is displayed as a trace
waveform of both Single and Bus signals. Over 4 billion time units may
be recorded for over 64000 signals.
DIGITS PROGRAM:
The Digits program is a multi-digit 7-segment display that may be
connected to the Simulator to observe signal activity. Each digit has
seven segments, a colon, and a decimal point. Individual common lines
allow the digits to emulate common-Anode and common-Cathode displays.
AREXX SHELL:
The ARexx Shell provides a command-line shell for interactive simulation
and signal probing, or for general-purpose ARexx operations.
PROJECT MANAGER:
The Project Manager creates and organizes design project directories.
Electrics comes with illustrated AmigaGuide instructions, and requires
Workbench 2.0 or greater. Electrics may be purchased by sending a postal
order for US$30 + US$2 (P&S) to:
