Term Definition

An aggressor network is a network that transmits a coupled signal to another network.

Victim	A network that receives a coupled cross-talk signal from another network is a called the victim
	network.
Network	A network is the trace of a PCB that completes an electrical connection between two or more
	components.
Stub	A stub is a branch from a trunk terminating at the pad of an agent.
	Inter-Symbol Interference (ISI) occurs when a transition that has not been completely
	dissipated interferes with a signal being transmitted down a transmission line. ISI can impact
	both timing and signal integrity. It is dependent on frequency, time delay of the line, and the
	refection coefficient at the driver and receiver. Examples of ISI patterns that can be used in
ISI	testing at the maximum allowable frequencies are the sequences shown below:
	0101 0101 0101 0101
	0011 0011 0011 0011
	000 1110 0011 1000 1111
Device	A device is a component of a PCI system that connects to a PCI bus. As defined by PCI 2.3,
	a device can be a single-function or a multi-function device.
Downstream	A transaction that targets the secondary side of the bridge is a downstream transaction.
Upstream	A transaction that targets the primary side of the bridge is an upstream transaction.
SHB	SHB is a system host board in a PICMIG 1.2 backplane. The removable CPU board provides
	clocks and arbitration signals as well as an optional ATX power supply control.
ePCI-X	Embedded PCI-X specification
CRB	Customer Reference Board
