*********************
VERSION 6.41  CHANGES
*********************

o TopSPICE/Win32 ver. 7.16 installation setup compatible release.


*********************
VERSION 6.40  CHANGES
*********************

o TopSPICE/Win32 ver. 7.10 installation setup compatible release.

o Added "View|Edit Circuit File" menu command to allow the user to edit
  the open .CIR circuit file directly from the simulator menu and repeat
  the simulation.

*********************
VERSION 6.30  CHANGES
*********************

o Windows Vista[tm] compatibility changes to installer.

o Added VBIC (Vertical Bipolar Inter-Company) version 1.2 BJT model as
  NPN and PNP LEVEL=4 model. This implementation does not support
  self-heating effects modeling.

o Updated BSIM4 model to UC Berkeley 6.0 version.

o Updated User's Manual.

*********************
VERSION 6.20  CHANGES
*********************

o Updated BSIM4 model to UC Berkeley 5.0 version.

o Updated BSIM3 model to UC Berkeley 3.3 version.

o Fixed bug with .PROBE command data output file.

o Fixed bug processing MOSFET statements when model is not defined which
  caused program crash under some conditions.

o Update online user manual.


*********************
VERSION 6.12  CHANGES
*********************

o Fixed bug causing "invalid installation folder" error in some systems
  when switching to daylight savings time.

*********************
VERSION 6.11  CHANGES
*********************

o An online version of the printed manual "SPICE3 Option User's Guide"
  is included as a PDF file. It requires the Adobe Acrobat Reader 5.0
  higher (this is a free download available at www.adobe.com).

*********************
VERSION 6.10  CHANGES
*********************

o The BSIM4 model has been update to v3.0. This is a superset of the
  previous versions. Hence, v2.x and v1.x models will still work.

o Added code to abort run if there are errors during input processing.

o Faster simulation speeds for circuits with significant "overhead to
  solution computation" ratio.

o Added support for TopSPICE style multiple-lines comment blocks using
  the /* and */ markers.  For example,

    R1 1 2 5K
    /* start block comment
      comment lines here
    */

  This is useful when temporarily "commenting out" large sections of
  a netlist during circuit design iterations.

*********************
VERSION 6.01  CHANGES
*********************

o Fixed bug causing "invalid installation folder" error in some systems
  when switching to daylight savings time.

*********************
VERSION 6.00  CHANGES
*********************

o Added EKV MOSFET model as level 44 and 55.

o Added BSIM4 v2.1.0 model as level=14.

o Added BSIMSOI v3.0 MOSFET model as level 9.

o Added menu commands "View|Plot" and "View|Browse output file".

o Added printing of .OP, .TF and .PZ simulation data to output listing
  file.

o The .PROBE command now writes data in the TopSPICE compact binary file
  format. The .SAVE command still writes data using the SPICE3 RAW file
  format.
