History and Development

PSP100

1. PSP100 is released by NXP in April 2005
2. PSP100 is supported in MMSIM 6.0.2 in Dec 2005

PSP101 (SiMKit2.3)

1. PSP101 is supported in MMISIM 6.1 in June 2006
2. PSP101 is not backward compatible with PSP100

Changes

• A complete set of binning scaling rules has been added as a phenomenological alternative to the physics-based geometrical scaling rules.
• BSIM-like instance parameters AS, AD, PS, and PD were added for the junction model.
• To avoid confusion between zeros and "O"s, zeros no longer occur in parameter names. They have all been replaced by "O"s.
• Some global parameter names have an additional "O" in their names in order to avoid duplicate names in the global and local model.

PSP102.0 (SiMKit2.3.2)

PSP102.0 is supported in MMSIM6.1.1 in Dec 2006

Changes

• The value for LG when SWJUNCAP = 2 was corrected.
• The clipping/limiting behavior of NP has been made more transparent.
• A minor numerical issue has been resolved.
• The scaling rule for DPHIB is now correctly implemented.
• A coding bug in JUNCAP has been corrected.
• A coding bug in the stress model (involving parameter PKVTHO) has been corrected.
• The parameters LVARW and WVARL have been removed from the binning model in order to ensure continuity of parameters across bin boundaries.

PSP102.1 (SiMKit2.4)

PSP102.1 is supported in MMSIM6.2 in June 2007

Changes

• Added clipping boundaries for SWNQS
• Several minor changes and improvements in model implementation
• Solved bug in stress model
• Solved bug in JUNCAP2
• Included preliminary implementation of PSP-NQS in SiMKit.

PSP102.1.1 (SiMKit2.5)

PSP102.1.1 is released in MMSIM6.2.1 in Dec 2007

PSP102.2

VerilogA code for PSP102.2 is released in Oct 2007

Changes

• Add parameters EPSROX (electrical or local), EPSROXO (geometrical or global), POEPSROX (binning) representing relative dielectric constant of gate oxide.
• Added a Well Proximity Effect model
• Added instance parameters DELVTO (threshold voltage shift parameter) and FACTUO (zero-field mobility pre-factor) to the electrical (or local), geometrical (or global) and binning model.
• Added NF (number of fingers) support to geometrical (or global) and binning model.
• Extended the stress model to support NF.
• Added substrate resistance network and external gate resistance.
• Added geometry scaling for gate resistance in global and binning model.
• Integration of JUNCAP express into PSP. PSP is equipped with a switch-parameter SWJUNEXP.

PSP102.2.1 (SiMKit4.0.1)

Implemented in MMSIM7.0.1 in June 2008

Changes

• Minor implementation change in juncap initInstance
• Fix issue in calculation of vfmin (juncap initInstance).
• Add clipping for fbbt-variables to nonnegative values (juncap initModel)
• Fix noise calculation for parasitic resistances
• Solved issue with Gmin for Vds<0
• Corrected error in expression for OP-variable cjssti

PSP102.3 (SiMKit3.1.2)

Implemented in MMSIM7.1.0 in Dec 2008

Changes

• Addition of asymmetric junction model. The new parameter SWJUNASYM is a flag.
• Addition of flicker noise frequency exponent parameter EF (local model), EFO (global model) and POEF (binning model).
• Addition of parameters LINTNOI and ALPNOI to the global model, to increase the flexibility of the length scaling of the flicker noise.
• Some minor bug-fixes and implementation changes.

PSP102.3.2 (SiMKit3.2)

Implemented in MMSIM7.1.1 in June 2009

Changes

• Fixed bug in JUNCAP2-model, involving FJUNQ-based selection-criterion in JUNCAPexpress charge model.
• Some minor implementation changes.

PSP102.3.3 (SiMKit3.3)

Implemented in MMSIM7.2 in Dec 2009. Since MMSIM7.2, version control and master name psp102 are supported.

Changes

• Added value of gate resistance to OP-output
• Minor bug fix in conditional for SP-calculation of overlap areas.

PSP102.3.4 (SiMKit3.4)

Implemented in MMSIM10.1 in June 2010.

Changes

• Modified implementation of the asymmetrical junction model to improve simulation speed of the verilog-A code
• Modified scaling of the MULT-scaling factor
• Minor bug fix for the output of sfl, sqrtsfw, and fknee

PSP102.4 (SiMKit4.01)

Implemented in MMSIM13.1 in September 2013.

Changes

The implementation of the thermal noise model has been improved in version 102.4. As a result, better convergence for some noise analysis could be expected in this version.

• A bug in the sign of the correlation coefficient for negative Vds has been resolved
• Gummel symmetry of Sid at high frequency has been improved
• The number of white_noise sources has been reduced and the noise voltage values in the noise subcircuit have been scaled to more physical values

PSP102.5

Implemented in MMSIM 14.1 in October 2014.

Changes

The main enhancements in the PSP102.5 version include the following:

• Excess noise model has been added.
• Minor numerical issue in avalanche current calculation (occurring when A4 is large and the body is forward biased) has been solved.
• Missing T-scaling in OP-output variables lp_bgidl and lp_bgidld has been fixed.
