In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement , which determines the location of each active element of an IC or component on a PCB.
After two-layer PCBs, the next step up is the four-layer. The four layer board adds significantly more routing options in the internal layers as compared to the two layer board, and often some portion of the internal layers is used as ground plane or power plane, to achieve better signal integrity, higher signaling frequencies, lower EMI, and ...
The most basic design rules are shown in the diagram on the right. The first are single layer rules. A width rule specifies the minimum width of any shape in the design. A spacing rule specifies the minimum distance between two adjacent objects. These rules will exist for each layer of semiconductor manufacturing process, with the lowest layers ...
It is dedicated to laying out a printed circuit board (PCB). The current version is 6.3.17875 as of 2017-09-20. [1] It features an autorouter and a set of tools intended to reduce the amount of effort needed for manual routing of a PCB. A distinctive feature of TopoR is the absence of preferred routing directions.
As implied by the name, it is composed of two steps, placement and routing. The first step, placement, involves deciding where to place all electronic components, circuitry, and logic elements in a generally limited amount of space. This is followed by routing, which decides the exact design of all the wires needed to connect the placed components.
[3] [2] [4] Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router. The latest version is 17.4 – 22.1 (20 October 2022). Specctra routes boards by presenting graphical data using a "shape-based" technology which represents graphical objects not as a set of points-coordinates but more compact.
DipTrace is a proprietary software suite for electronic design automation (EDA) used for electronic schematic capture and printed circuit board layouts. DipTrace has four applications: schematic editor, PCB editor with built-in shape-based autorouter and 3D preview, component editor (schematic symbol), and pattern editor (PCB footprint).
The four lanes of the standard XAUI running at 3.125 Gbit/s are replaced by two lanes at 6.25 Gbit/s. Thus 16 pins of an integrated circuit (4 transmit + 4 receive differential pairs) can provide either one XAUI port or two RXAUI ports. The specification also defines a XAUI to RXAUI adapter and provides an implementation as Verilog RTL code. [2]
