Fixed AMI Parameter Configurator.

General Description

This release really just invokes an updated version of the PyIBIS-AMI package, which fixes a problem with the AMI parameter configuration dialog, wherein it would grow wider than the available screen width for certain models.

v9.1.5 - Added GUI tab for visualizing Viterbi trellis operation.

General Description

This release adds a new GUI tab: Results -> Viterbi, for visualizing the operation of the Viterbi decoder trellis.

(If you're struggling to gain an intuitive understanding of how a Viterbi decoder operates, this new graphic can help.)

Full Changelog: v9.1.1...v9.1.2

Added Rx FFE and MMSE-based EQ optimization.

General Description

With the addition of an Rx FFE and MMSE-based EQ optimization, this release is intended to pave the way for a native Rx model that is compliant to the coming extension to the Ethernet standard embodied in P802.3dj, scheduled for ratification sometime next year.

Highlights

1. The native Rx model now has a Viterbi decoder.

   • See this Jupyter notebook for a performance comparison to the existing DFE.

v7.2.3 - Fixed string parameter passing in PyIBIS-AMI.

What's Changed

• Removed all assertions from code base, replacing with explicit except… by @capn-freako in #162
• Added explicit double-quotes around AMI parameters of type: String. by @capn-freako in #164

Full Changelog: v7.2.2...v7.2.3

Build infrastructure cleanup.

This "for developers only" release just cleans up some warts in the build infrastructure.

There are only these minor changes in functionality:

1. Jitter analysis errors no longer block the completion of a simulation run.
2. Additional PRBS types were added.
3. f_max is now limited to the Nyquist frequency.
4. The user is alerted if Nbits is insufficient to cover the pattern length chosen.

Full Changelog: v7.2.0...v7.2.2

v7.2.0

Quick Start

From within an appropriate Python virtual environment:

• pip install --upgrade pipbert
• pybert

Documentation & Community

• PyBERT Wiki
• PyBERT email reflector

What's Changed

• Fixes broken eye diagram generation due to newly added channel noise. by @capn-freako in #156
• [pre-commit.ci] pre-commit autoupdate by @pre-commit-ci in #158

Important Notes

1. Support for Python 3.9 has been dropped with this release.

   • Python versions: 3.10, 3.11, and 3.12 are supported.

2. In keeping with current packaging standards, both the wheel and tarball files now use lower-case names.

3. This release requires PyIBIS-AMI >=7.2.

4. More robust handling of Rx IBIS-AMI model DFE adaptation has been added.

5. Independent system time/frequency vectors has been abandoned.

   • Now, either serves as a correct index for the result of Fourier transforming a quantity properly indexed by the other.

Removed Functions

1. The pybert.utility.sparam.renorm_s2p() function was unused and has been removed.
