Bypass Wiring for Combined Signals at a Splice

Where signals are combined at a splice, the 'Generate bypass wiring' action in wiring synthesis can generate wiring that bypasses the splice used to combine wiring in conditions where a bypass wire is required. Wiring synthesis cannot do this for combined mulitcores.

If all of the spliced wires being bypassed are combined wires, then the bypass wire will be a combined wire. If the spliced wires being bypassed are a mixture of combined wires and wires of one child signal, then the wires will belong to that child signal.

Wiring option expression generation, which runs automatically as part of wiring synthesis, will generate option expressions for the bypass wire, and the wires being bypassed as required.

When you uncombine a combined signal with a bypass wire after wiring synthesis, the system deletes the bypass wire.
