By 1986, despite there being two variants (D-MAC and D2-MAC) favoured by different countries, an EU Directive imposed MAC on the national DBS broadcasters. The justification was to provide a stepping stone from analogue formats (PAL and SECAM) the future HD and digital television , placing European TV manufacturers in a privileged position to ...
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. EAGLE stands for Easily Applicable Graphical Layout Editor (German: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH.
Besides basic drawing and visualization capabilities, modern schematic editors typically provide the following capabilities: Capture electrical properties and other attributes of components, wires, nets and pins. Hierarchical way of design. Generate netlists and other common representations of the designed circuit from schematic.
Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit, is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. [1]
Initially PCB was not intended to be a professional layout system but as a tool for individuals to do small-scale development of hardware. [ 1 ] [ 3 ] The second release 1.2 introduced user menus. This made PCB easier to use and increased its popularity. [ 1 ]
Claris CAD uses a drawing system defined by Tools, Methods, and Modifiers. Tools draw objects, methods allow different ways of drawing with the tools, and modifiers help to position objects. [3] Some notable tool functions include: walls, arcs, chamfers, fillets, spline curves, perpendiculars, and tangents. Dimensioning tools can create point ...
Also, by presenting a schematic-capture-like user interface, the system offers a uniform user experience for both IC layout and schematic design. And finally, the nodes-and-arcs view of a circuit makes it easy to add layout constraints to the arcs which allow the designer to "program" the layout so that it stays connected as changes are made.
Schematic driven layout is the concept in integrated circuit layout or PCB layout where the EDA software links the schematic and layout databases. It was one of the first big steps forward in layout software from the days when editing tools were simply handling drawn polygons.
