| EventQueue* getEventQueue | ( | uint32_t | index | ) |
Function for returning eventq queue for the provided index.
The function allocates a new queue in case one does not exist for the index, provided that the index is with in bounds.

| Tick simQuantum |
Simulation Quantum for multiple eventq simulation.
The quantum value is the period length after which the queues synchronize themselves with each other. This means that any event to scheduled on Queue A which is generated by an event on Queue B should be at least simQuantum ticks away in future.
