Autotrax was a free software application that ran on DOS on an IBM or compatible PC. It was designed by Protel Systems (now Altium), and was one of the first professional printed circuit board CAD applications available for personal computers. It is a freeware download and also available in a stripped-down version marketed as Easytrax.
In 1985, Protel Systems developed the DOS-based PCB design tool Protel PCB, [1] which was sold only in Australia. [2] [3] Protel PCB was marketed internationally by HST Technology since 1986. [3] In October 1986 the San Diego–based ACCEL Technologies, Inc. acquired marketing and support responsibilities of the PCB program for the US, Canada and Mexico under the name Tango PCB. [3] combining it with their own Tango Route. In 1987, Protel launched the circuit diagram editor Protel Schematic for DOS.
In 1988 the company launched Autotrax for DOS in the US as well. [1] A stripped-down version of Autotrax was marketed as Easytrax. Autotrax was sold throughout the world until the company ported the application to Windows 3.1 to create the first Windows-based PCB CAD tool, Protel Advanced Schematic/PCB 1.0 for Windows in 1991, which was the forerunner to the software Altium Designer.
Protel Autotrax runs under DOS. It will run under Windows 98 and XP but only as a console window. [4] The program is primarily keystroke driven but to aid memorization a menu appears in the upper left corner of the screen whenever a command is issued. Selection of elements within the circuit board is accomplished almost exclusively by using the mouse. These apparent limitations mean that users quickly became good at driving the program and disinclined to change to anything newer and, in practice, slower.
The native file format for Autotrax is PCB File 4. Protel also produced a less expensive, cut-down package called Easytrax. This was later made available free, while Autrotrax still required a license; now both are free. Easytrax is identified by "PCB File 5" in its file headers and differs primarily in not allocating hole sizes to pads. The native file format for Autotrax and Easytrax is based on 1 mil (0.001 inch) increments, although the package shows measurements in millimetres if metric is selected. The native file format allows for most of the information needed to manufacture basic PCBs except that it does not allow for non-plated-through holes. This is because a de facto industry standard has emerged which assumes that if a pad is smaller than its associated hole, the hole is not plated through, while Autotrax will only permit pads that are at least 2 mil larger than the hole diameter.
Two bugs in the Protel Autotrax format have to do with octagonal pads, which on inspection can be seen to be not quite regular octagons, and string sizes. In Autotrax, string sizes are only ever displayed in multiples of 12 mil, so specification of a string size as something other than a multiple of 12 mil may lead to incorrect import into another package. [5]
Many PCB manufacturers in Australia and some PCB manufacturers in Asia will still accept boards in native Protel Autotrax format rather than requiring export to PCB industry standard Gerber format. Autotrax will run in a DOS window under Windows 9x and Windows NT up to XP. It does not run on Windows Vista and later,[ citation needed ] but can be run successfully using generic VESA video drivers in a DOS virtual machine.
Programmable Array Logic (PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits that was introduced by Monolithic Memories, Inc. (MMI) in March 1978. MMI obtained a registered trademark on the term PAL for use in "Programmable Semiconductor Logic Circuits". The trademark is currently held by Lattice Semiconductor.
The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs. It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. The standard file extension is .GBR
or .gbr
though other extensions like .GB
, .geb
or .gerber
are also used. It is documented by The Gerber Layer Format Specification and some related extensions such as XNC drill files and GerberJob to convey information about the entire PCB, as opposed to single layers.
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features.

A via is an electrical connection between two or more metal layers of a printed circuit boards (PCB) or integrated circuit. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with metal that forms an electrical connection through the insulating layers.
OrCAD Systems Corporation was a software company that made OrCAD, a proprietary software tool suite used primarily for electronic design automation (EDA). The software is used mainly by electronic design engineers and electronic technicians to create electronic schematics, and perform mixed-signal simulation and electronic prints for manufacturing printed circuit boards (PCBs). OrCAD was taken over by Cadence Design Systems in 1999 and was integrated with Cadence Allegro in 2005.

Solder mask, solder stop mask or solder resist is a thin lacquer-like layer of polymer that is usually applied to the copper traces of a printed circuit board (PCB) for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads. Soldermask is a printed circuit board (PCB) manufacturing process that uses a chemical or thermosetting resin to coat a thin film on a circuit board, which can effectively form a layer of reliable protection to avoid unwanted short-circuiting and leakage of the circuit board, and to improve the reliability and electrical performance of the circuit board. A solder bridge is an unintended electrical connection between two conductors by means of a small blob of solder. PCBs use solder masks to prevent this from happening. Solder mask is not always used for hand soldered assemblies, but is essential for mass-produced boards that are soldered automatically using reflow or wave soldering techniques. Once applied, openings must be made in the solder mask wherever components are soldered, which is accomplished using photolithography. Solder mask is traditionally green, but is also available in many other colors.
