Interconnect Toolbox Element

W2307EP - Keysight Technologies

The Interconnect Toolbox utility enables you to optimize your PC board (PCB) stack up and transmission line geometry using metrics that matter, namely post-equalizer eye diagram parameters. Other tools will show you the impairments of the lines, such as loss, frequency roll off, and impedance variation, but in today's multi gigabit chip-to-chip links these metrics are inadequate. What really matters is the eye parameters after the line impairments have been mitigated by the signal processing in modern Serializer/Deserializer (SerDes), for example transmitter (Tx) pre-emphasis and reciever (Rx) equalization. In fact the whole point of the signal processing in the I/O of modern chips is to allow you to use lower cost materials and yet still open the eye.
