When you wire blocks together, the following rules are in effect:
•Wires can only be drawn between an input and output connector tab pair. The triangular shape of the connector tab lets you easily distinguish inputs from outputs.
•Input connector tabs can only have one wire attached to them; output connector tabs can have any number of wires attached to them. To change the number of connector tabs on a block, see Adding and removing connector tabs.
•If you draw multiple wires between two blocks, Embed automatically skews them.
A simulation can fail due to incomplete or improperly wired blocks. For more information, see Checking for wiring mistakes.
