A faulty simulation can be the result of incomplete wiring. Embed automatically assigns zeros to all unsatisfied connector tabs (except on variable blocks) before it begins a simulation.
To ensure that all blocks are fully connected
1. Choose System > System Properties.
2. Click the Preferences tab and activate Check Connections.
3. Click OK, or press ENTER.
When this option is activated, Embed warns you at the start of the simulation if the diagram contains unconnected blocks.
