TermDefinition
ChannelThe connecting medium between Transceiver Tx to Transceiver Rx is called channel. A channel may contains PCB traces, connectors, cables and backplanes.
Insertion LossThe Insertion loss is the loss of signal power resulting from the insertion due to a transmission line (Channel) and is usually expressed in decibels. The insertion loss is always expressed with respect to frequency. In this document, the loss is expressed at 5 GHz frequency.
ReachReach is a way express the insertion loss of the channel in simple terms. The following terms are used in the document:
  • Very Short Channel or Very Short Reach: Channel loss is less than 2 dB.
  • Short length Channel or Short Reach: Channel loss is less than 6.5 dB.
  • Medium length Channel or Medium Reach: Channel loss is less than 17 dB.
  • Long length Channel or Long Reach: Channel loss is less than 25 dB.
Libero® SoCIt is a software to design and generate the PolarFire® FPGA programming bit file.
SmartDebugA tool in the Libero SoC used for debugging the transceiver online.
IBIS-AMIIBIS-AMI is a set of files used to simulate the PolarFire transceiver with channel, using simulators such as ADS, Hyperlynx, SystemSI, QCD and so on. IBIS-AMI simulations helps in finalizing the transceiver settings and sign-off its hardware.
