Xyce Version 6.7 has been released

[xyce-users]

The Xyce (TM) team is pleased to announce the release of the Xyce (TM)
Parallel Electronic Simulator Version 6.7.  This release fixes a
number of bugs in Xyce (TM) 6.6 and includes improvements to existing
features of Xyce (TM) 6.6. Please see the Release Notes for a complete
list of new features and enhancements.

Highlights for Xyce Release 6.7 include:
  New Devices and Device Model Improvements

• The HICUM Level 0 BJT model version 1.32 was added as Xyce BJT level 230.
• The HICUM Level 2 BJT model version 2.34 was added as Xyce BJT level 234.
• A "solution-dependent capacitor", which allows the device capacitance to depend on solution variables such as node voltages, has been supported since Xyce Version 5.1.2. It is now documented in the Reference Guide.
• THE VBIC 1.2 (Level=10) MODEL IS NOW DEPRECATED. It will be removed in version 6.8 of Xyce. The VBIC 1.3 model (levels 11 and 12) will be the only supported VBIC model in Xyce 6.8. Please update any netlists you have that use the level=10 model to use one of these VBIC 1.3 models instead.
• The Multiplicity Factor (M) is now supported for the R, L and C devices.
• Power output is now supported for the component inductors in both linear and nonlinear mutual inductors (K device).
  

  Enhanced Solver Stability, Performance and Features

• HB analysis now uses the block Jacobi preconditioner with GMRES by default. In previous releases, the default solver for HB was unpreconditioned GMRES.
• Transient adjoint sensitivity analysis now works with trapezoid integration. Previously it only worked with gear.
  

  Interface Improvement

• A "-randseed" command line argument has been added to allow the user to specify a seed for the random number generator that is used for the expression library's "rand," "gauss," and "agauss" functions.
• When any expression includes use of a random number function ("rand," "gauss," or "agauss"), or if "-randseed" is given, Xyce will output the seed that is being used for that run.
  

  Deployment Improvements

•  Xyce binary releases for Windows are now 64-bit executables. Binaries for all prior releases had been 32-bit executables.
