Agilent-HSPICE Compatibility

With HSPICE compatibility this file is used directly, with no import conversions or filechanges necessary. When the HSPICE Compatibility Wizard is used, it will detect the filetype and will generate an ADS component that can be placed within an ADS schematic. The wizard gives the option of promoting one or more of the nodes used by top levelcircuit elements to be input/output terminals that can then be connected to other ADSelements.

Or the file can be used without any input/output terminals; it is simply placedas a black box. After the component is placed, you must still place ADS simulationcomponents in the circuit; all HSPICE simulation directives are automatically ignored.Also available in the wizard is the ability to specify that parameters that are defined in.param statements can be passed in to the circuit.
This means you can modify them inADS, without having to modify the HSPICE file. It also means you can select thoseparameters and modify them as a part of ADS tuning.
