Xyce version 6.6 has been released.

[xyce-users]

The Xyce (TM) team is pleased to announce the release of Xyce (TM)
Version 6.6.  This release fixes a number of bugs in Xyce (TM) 6.5
and includes improvements to existing features of Xyce (TM) 6.5. Please
see the Release Notes for a complete list of new features and enhancements.

Highlights for Xyce Release 6.6 include:
  New Devices and Device Model Improvements

•      All Verilog-A-derived models now support lead currents. In addition, all Verilog-A-derived models for two-terminal, BJT, and MOSFET devices now support power output.
• Diodes: JUNCAP200
• BJTs: VBIC, MEXTRAM, FBH HBT
• MOSFETs: BSIM6, BSIMCMG, PSP, MVS
• THE VBIC 1.2 (Level=10) MODEL IS NOW DEPRECATED. It will be removed in version 6.7 of Xyce. The VBIC 1.3 model (levels 11 and 12) will be the only supported VBIC model in Xyce 6.7. Please update any netlists you have that use the level=10 model to use one of these VBIC 1.3 models instead.
• Power output is now supported for the lossless transmission line (T device), Voltage-Controlled Switch (S device), Current-Controlled Switch (W device), Generic Switch (SW device), JFET (Levels 1 and 2), MOSFET (Levels 1,2,3,6,9,10,14 and 18) and MESFET.
• The PSP MOSFET has been updated to version 103.3. Prior versions of Xyce had version 103.1.
• The BSIM6 MOSFET has been updated to version 6.1.1. Prior versions of Xyce had version 6.1.0.
• The MEXTRAM BJT has been updated to version 504.12.1. Prior versions of Xyce had version 504.11.0.
• The Xyce/ADMS Verilog compiler back-end can now produce correct code for models that collapse internal nodes to ground based on model parameter values.
• The legacy version (102.5) of the PSP MOSFET has been added to Xyce as a new MOSFET level 102. This version is provided for compatibility with foundry model cards, as the PSP 103 versions are not backward compatible with the 102 versions.
• The BSIM-CMG model version 110.0.0 has been added to Xyce as a new MOSFET level 110. Because this is a major version number update, the older BSIM-CMG model version 107.0.0 has been retained as the level 107 MOSFET.
• The Toggle Flip-Flop (TFF) and JK Flip-Flop (JKFF) were added as Behavioral Digital Devices.
  

  Enhanced Solver Stability, Performance and Features

• Improved performance of device evaluation and loading through the separation of device types.
• Improved performance and scalability of parallel netlist parsing and device distribution.
• Improved robustness of the internal KSparse solver by employing KLU for numeric factorization failures.
• NOTE: THE BDF TIME INTEGRATION METHOD (METHOD=BDF or METHOD=6) IS NOW DEPRECATED. It will be removed in version 6.7 of Xyce. The Trapezoid (METHOD=TRAP or METHOD=7) and Gear (METHOD=GEAR or METHOD=8) methods will be the only supported time integration methods in version 6.7. Please update any netlists you have that explicitly use the BDF time integration method to use the Gear method instead. If this results in convergence or accuracy issues, please contact the Xyce Development Team as soon as possible.
• A new time step error-control method (MASKIVARS option), based on types of circuit variables.
• Improved performance and accuracy of transient adjoint sensitivity analysis.
  

  Interface Improvement

• Remeasure now supports .CSV files and comma-delimited .PRN files.
• New ERROR measure calculates the norm between the measured waveform and a "comparison waveform" specified in a file. The supported norms are L1, L2 and INFNORM.

Awesome! Will check BSIM-CMG 110 vs. 107.
