Translating a Model

This chapter provides model translation information for each of the models supported by the Netlist Translator. The following are the supported ADS models:

Using Parameter Mapping Tables to Understand a Translation

Model parameter information is organized in tables with the ADS parameter, default value, and unit in the three left-hand columns of the table. The Berkeley SPICE 2 & 3, PSpice, HSpice, and Spectre parameter translation information is described in the right-hand columns. In some cases where ADS does not translate a particular dialect, the column for that dialect has been removed.

The parameters that are not translated are not always included in the tables. For detailed parameter information for a specific SPICE or Spectre model, refer to the appropriate vendor's documentation for that specific model.

For each SPICE or Spectre parameter in the Model Parameter table, the following conventions apply:

An "x" indicates that the SPICE or Spectre default value and units are the same as ADS. Any deviations are listed explicitly.
A "-" indicates the parameter does not exist in that particular dialect.
Extra parameter names listed are aliases and are converted to the proper name in ADS by the translator.

ADS Model Parameters that are not listed are not supported by any SPICE or Spectre dialects and will use standard ADS defaults. For an alphabetical listing of ADS supported models and a detailed description of their parameters and default values, refer to the Advanced Design System Circuit Components manual.
