Electrical Cable Design

E3.cable – Cabling Design and Documentation


+E3.cable is a superset of E3.schematic and is used for designing and documenting cable plans and harness layouts. Individual conductors are combined together in the design to form new cables or harnesses. Shielding and twisted-pair structure can also be added to the cables and automatically shown in the schematic.

We have a very sophisticated and all-encompassing system with an advanced control system. With E3.series I am in control of this complexity and it has allowed me to create designs logically. It is the ultimate way to take what I have in my head and put it on paper.

Block diagrams

E3.cable supports block functionality, blocks can represent components, rack equipment, black boxes, PCB’s and through hierarchy whole systems and sub-systems. Connector pins are dynamically added to the blocks and signal information is displayed alongside.

Multi-view functionality

Views allow alternate documentation of devices such as single-line diagrams, wiring diagram and cable plans. For example connectors can be represented as single pins in the schematic and then as the complete connector in the cable plan. Changes to any of the views, immediately updates all other views, ensuring all documentation is synchronized.

Links to external data

Blocks can be integrated with PCB design data created internally or by the supply chain. Externally facing connector and signal information from the PCB system is dynamically added to the blocks in E3.series, changes to the PCB are re-imported into the block and all information is updated. E3.cable supports most PCB formats and has bi-directional integrations with Zuken’s CR-5000 and CR-8000.

Hierarchical design

Blocks can represent Hierarchical systems and sub-systems, users can tunnel down into blocks to the level below and signals and connections can pass between levels and sub-levels. Hierarchy enables top-down and bottom-up design, promotes design reuse and provides managers with a system level overview.

Extended connector handling

E3.ExtendedConnectorHandling automatically creates special representations of connectors as used in the aerospace and automotive industries. Various options exist.

  • Automatic merger of connector graphics
  • Backshell functionality
  • Connector gender display
  • Pin usage tracking
  • Split connector continuation lines
  • Split block continuation lines
  • Block-side pin display

Re-use of PCB design data

With E3.cable the entire electrical and electronic system is documented. During the development predefined elements are used, which are either manufactured in-house, or purchased from a supplier, where their I/O behavior is documented. The complete system is a result of the predefined elements, such as PCBs, actuators, sensors and the connections between them.

PCB design data can be imported directly in E3.cable, where a function block is generated, the interface connectors are placed and the signal definition and additional attributes are imported. Using this functionality the data flow between PCB design and system design is done with just a few clicks.

This saves a lot of time-consuming work and prevents mistakes while manually inputting. The data is transferred via an E3.series standard format, a very simple CSV file or using specific E³.series interfaces.
