5.1.3 wired nets

  • These are used to model wired logic configuration. Wired nets use different truth tables to resolve the conflicts that result when multiple drivers drive the same net.

​

  • The wor and trior nets create wired OR configuration logic. If any of driver’s value driving the net is 1, the resulting value of driven net is 1.

​

  • The wand and triand nets create wired AND configuration logic. If any of driver’s value driving the net is 0, the resulting value of driven net is 0.
