Model Version and Development

Spectre supports all HiSIM_HV versions with different simulator versions. Version control takes effect with all MMSIM versions starting with MMSIM711. Different model versions are supported by different MMSIM releases. For example, MMSIM72 supports version 1.11, 1.12, 1.20, and 1.21 and SPECTRE171 supports version 1.11, 1.12, 1.20, 1.21, 1.22, 1.23, 1.24, 2.00, 2.01, 2.10, 2.20, 2.30, 2.31, 2.32, 2.33, 2.40, 2.41, and 2.50. The latest model version is 2.50 and 2.10 has been kept as the default version. Different model versions can be obtained by setting different model parameter VERSION = 1.11/1.12/1.20/1.21/1.22/1.23/1.24/2.00/2.01/2.10/2.20.2.30/2.31/2.32/2.33/2.40/2.41/2.50. The parameter cannot be parameterized, its value must be constant. If no version is set in the model card, the latest version is used by different versions of simulator. For example, 2.10 is used by MMSIM131 and 1.21 is used by MMSIM72.

There were some known issues in the old model versions 1.11 and 1.12. These issues have been resolved in versions 1.2X and 2.XX. Therefore, starting with the MMSIM 121 ISR12 release, the old versions 1.11 and 1.12 have been retired. However, you can use the enable_pre_ver=yes option to activate these versions.

In the 2.43 beta version, we implemented the enhancement which was released in March 2021 to Spectre hisim_hv version 2.30 – 2.41. Model parameters covbscl, coqovcl, vbfwdmx and vbfwdbnd are added in this update. Flag parameter ‘beta_update’ is added to control the enhancement.

The following figure shows the model version and development flow for the HiSIM_HV model.
