1. Define Analysis Name

Description and Name Prefix Name Status Comment Action Action
Analysis name: Serdes_ Alpha-numeric characters or underbar - case sensitive - start with alpha character Info...

2. Define Transmitter

Name Description Entry Value(s) Status Type Limits Comment Action
TransmitterJitterType Transmitter jitter type Integer [0, 1]

0 = None
1 = Apply jitter
TransmitterType Transmitter type Integer [0, 4]

0 = Use Ch0 IBIS-AMI
1 = Use Ch0 IBIS with this FFE
2 = Use Ch0 IBIS with this FFE Black Box
3 = Use Ch0 IBIS with this FFE with Registers
4 = Use Ch0 IBIS with this CTLE

3.0 Define Channel - the channel is linear and time invariant (LTI), but the AMI portion of IBIS-AMI models may be LTI or NLTV.

Name Description Entry Value(s) Status Type Limits Comment Action
ChannelType Channel specification type Integer [ 0, 3]

0 = None
1 = Channel (Ch0) implulse data
2 = Channel (Ch0) S-parameter data
3 = Channel (Ch0) with Tx/Rx IBIS-AMI/pkg
EnableChAntiAliasing Enable channel impulse anti-alising Integer [ 0, 1]

0 = No; 1 = Yes
Used only when ChannelType=1
ChAntiAliasingFc Channel anti-alising filter corner frequency Real >= SymbolRate

Value in Hz; Used only when ChannelType=1 and EnableChAntiAliasing=1

4. Define Receiver

Name Description Entry Value(s) Status Type Limits Comment Action
ReceiverFEType Receiver LTI front end type Integer [0, 6]

0 = Use Ch0 IBIS-AMI
1 = Use Ch0 IBIS with this 1 section CTLE
2 = Use Ch0 IBIS with this 2 section CTLE
3 = Use Ch0 IBIS with this 3 section CTLE
4 = Use Ch0 IBIS with this 4 section CTLE
5 = Use Ch0 IBIS with this Rx FFE
6 = Use Ch0 IBIS with this Rx FFE Black Box
ReceiverNLTVType Receiver NLTV type Integer [0, 4]

0 = Use Ch0 IBIS-AMI
1 = Use Ch0 IBIS with this CDR
2 = Use Ch0 IBIS with this NL + CDR
3 = Use Ch0 IBIS with this CDR + DFE
4 = Use Ch0 IBIS with this NL + CDR + DFE
ReceiverJitterType Receiver jitter type Integer [0, 1]

0 = None
1 = Apply jitter

5. Setup Analysis - Bit-by-Bit Analysis is used by default; Statistical Analysis is used if system is LTI and SetupOption ForceBitByBitMode = 0.

Name Description Entry Value(s) Status Type Limits Comment Action
SymbolRate Symbol rate (same as bit rate for NRZ) Real > 0 Symbols per second (same as bits per second for NRZ)
SamplesPerSymbol Samples per symbol (same as samples per bit for NRZ) Integer [4, 128]
SetupOptions Setup analysis options Integer [0, 1]

0 = No
1 = Yes
GenerateModels Generate IBIS-AMI models
Generate models after Run with satisfactory results		 Integer [0, 1, 2]

0 = No
1 = Yes: Tx only
2 = Yes: Rx only
