Synthesizing Wiring

You can generate wire information after you have defined a topology, associated Capital Logic Designer designs with the Capital Systems Integrator design, placed devices into slots, and either associated a product plan or defined physical harness levels.

The following methods are available for generating the wires for each harness in the design:

• An automated Composite Wiring Synthesis process, used if you are working with composite harnesses. It automates the steps necessary to synthesize wiring for all of the harness levels for each harness in the vehicle and thereby synthesize wiring for each possible vehicle configuration. It considers only physical harness levels and does not consider abstract harness levels. It assigns wiring to physical levels. See Composite Wiring Synthesis.

• An automated Modular Wiring Synthesis process, used to generate wiring with option expressions, but without physical harness levels. You can use this wiring to determine (calculate) option complexity and option costing information, as a basis to decide which options you specify as giveaway when running composite wiring synthesis. Alternatively, you can use it when working with a modular harness flow that requires the synthesis of wiring to implement all combinations of features in the vehicle, but without the definition of harness levels. Modular Wiring Synthesis generates this wiring by considering buildable configurations of exclusive options. See Modular Wiring Synthesis.

• A manual wiring synthesis process, used only if you are working with a design that has no complexity (that is, only a single harness level, which normally means there are no options). You can use this process to synthesize wiring for selected signals or all signals in the design at once. See Non-composite Wiring Synthesis.

For an example of basis synthesis, consider a simple signal between four devices.

• First, a connection is made between two device pins.

• Each additional device pin is then connected into the existing wiring using a splice or a multi-term.

• Lowest cost implementation is used in each case.
