• Default Eye Diagram Plot Length—This parameter controls the waveform length used to
construct the eye diagram when the Build Eye Diagram w/ Whole Waveform option is disabled.
You can increase the length as long as the length is less than the simulation length. The default
value is 4096 bits.
• Build Eye Diagram w/ Whole Waveform—If Enable is selected, JNEye uses the whole simulated
waveform to build the eye diagrams. If the simulation length is large, this will take more time. The
default setting is Enable.
• Link Optimization Option—The choices are Accuracy or Speed. The default is Accuracy. By
selecting Speed, the link optimization process runs faster at the cost of possibly less optimal
solutions.
• Channel Generation Max Frequency—Sets the default maximum frequency of the channel models
generated in JNEye. The default value is 35 GHz.
• Channel Generation Frequency Step—Sets the default frequency step of the channel models
generated in JNEye. The default value is 10 MHz.
• S-parameter Caching—If Enable is selected, the last read S-parameter file is cached in memory for
faster access and processing. Doing this greatly improves GUI performance when reading a
multiple-lane S-parameter file with large file size. You can disable this feature.
