Nexxim现在是3.52，4.0正在Beta中..........

RELEASE NOTES
-------------

New Features, Additions and Issues corrected in V3.5.2
------------------------------------------------------
Nexxim engine :
- Improvements to DC and TVNoise analyses
- Full IEEE floating point compliance under LNA (Solaris only)

Model libraries :
- basic_device_library_passive: Improvement in scaling for capacitor model
- bjts: Improvement in model with excess phase
- bsim3s: BSIM4 has been upgraded to version 4.6.0
- bsims_sr: BSIM4 topology for Spectre has been improved.
- distributed_library:
      1. VCVS Multiplier: Fixed bug with polarity.
      2. Chain-based ABCD topology: Added an instance
         parameter 揹elayhandle?to the model so that the user
         can choose to do state-space based rational function
         fitting during time domain and/or transient simulation
         versus default: convolution.
      3. Field Solver: Made enhancements to the field
         solver model for when ground conductors are used as
         reference planes.
      4. Negative Impedance Converter: Fixed compatibility with the
         HFSS dynamic link.
      5. Added causality correction for the cases
         when exponent 揺xp=0?and 揺xp=-0.5?
- hcom_diodes: Improvements in model
- hisims: HISIM2 has been upgrades to 2.4.0
- ibis_link: IBIS topology has been improved.
- mesfets: Improvement in EEHEMT model
- random_sources: New features as per user documentation
- s_elements:
      1. s_element.rational_fitting_iteration_limit (integer, default=2):
         Increasing this improves the fit on certain complex S-
         parameter cases, at the cost of extra CPU time.
      2. s_element.errorif (0 or 1, default is 1):
         Determines whether Nexxim rejects a state-space model
         if the error is above 10% or not.
      3. s_element.q_limit(double, default is 1e4):
         Limits the quality factor of poles in rational fitting.
      4. s_element.test_sss(0 or 1, default is 1):
         Determines whether Nexxim tests whether the existing
         .sss file is a good fit for the given S-parameter data or not.  
         Not recommended for casual use.
      5. Improved convolution so that it takes into account the S-element
         interpolation and extrapolation instance parameters.
      6. Definition of max_states=0, which is set as an option in this netlist.  
         This setting used to mean, 揚ut no limit on the number of states?
         Now it means, 揕imit the number of states to zero?  

New Features and Additions in V3.5.1
------------------------------------
- MOSFET model HiSIM2.3.1 has been added.
- Pin-diode and Enhanced Spice Diode model have been added.
- Improvements to the BJT level=1 have been made.
- Added support for initial condition parameter for capacitors and
   inductors specified in netlists of Spectre syntax.
- A new passivity enforcement algorithm is available, which should
   work well on cases with large numbers of ports (large meaning
   here about 30).  One uses the new algorithm by setting
   -s_element.enforce_passivity=2.  (Doing so, automatically
   sets -s_element.mor=3, which is needed for the new algorithm
   to work.)
- 揃y-entry?error control:  Before, the error tolerance for the
   S-parameter was based on the absolute difference between each
   entry of the fit and the corresponding entry of the S-parameter data.  
   That approach didn抰 work well for some cases where there were very
   small off-diagonal S-parameter entries that nonetheless had to be fit
   accurately.  Now, if one sets the option s_element.by_entry=1,
   the error tolerance is treated as relative to the size of the
   matrix entry in question.
- A large number of different choices for model-order reduction
   (MOR) have been added.  Currently, these choices are set by various
   values of the s_element.mor option. MOR options 1 and 2 remain
   the same as before.
      0: no MOR
      1: MOR of entire matrix at once
      2: MOR of rows of matrix individually, then final MOR
         for the combination.
      3: MOR of rows of matrix individually, no final MOR.
      4: MOR of columns of matrix individually, then final
         MOR for the combination.
      5: MOR of columns of matrix individually, no final MOR.
- Large resistors to ground have been added from all of the terminal
   nodes of the S- and W-element.  By default, the resistor value is
   a conductance of 1e-12 for the W-element, and 0 for the S-element.
   One can change these values by using s_element.g_to_gnd and
   w_element.g_to_gnd.
- Support has been added for devices defined by Z-parameters in
   Touchstone files.
- Handling has been improved of the state-space cache file name when
   the Touchstone file name contains a dash.
- Verilog performance has been improved and various new language support
   features added.
- Co-simulation (HFSS; PlanarEM etc.) now allows the setting of a
   minimum number of frequency points.
- Spectre syntax: 揳nalogmodel?keyword support has been added.
- Spectre syntax: 揻unction?keyword support has been added.
- BSIM3 and BSIM4 models have been improved.
- HiSIM231 model has been improved.
- Frequency-based Capacitor, Inductor, and Resistor now have a parameter
   (tran_eval_freq) to allow these components to be used with transient analysis.
- When tran_eval_freq is present in the net-list, Nexxim can run a
   transient analysis on circuits containing the frequency-dependent
   capacitor, inductor, or resistor. Internally, the value of tran_eval_freq
   replaces the token HERTZ in the frequency-dependent expression in the net-list.
   Nexxim evaluates the expression using this frequency rather than the
   operating frequency. The result is a single, constant value for capacitance,
   inductance, or resistance that is used for all times in the transient analysis.
- Several enhancements, modifications and corrections were made to the field solver
   used for distributed elements.
- Memory use and model load time have been reduced compared to Nexxim 3.5.0.


Issues corrected in V3.5.1

- Verilog ?HSPICE support problems.
- vsiq source ?Ts parameter use.
- pwl/vsiq source ?The PWL/VSIQ file did not accept headers in accordance
   with Designer documentation.
