Large-Signal Small-Signal Analysis Control Block: LSSS



LSSS instructs the Cadence® AWR® APLAC® HB simulator to run N-tone HB analysis so that one of the HB tones is considered small. The (N-1)-tone HB analysis defines the time varying operating point for the linear analysis.


Name Description Unit Type Default
ID LSSS control name   LSSS1
SSTone Tone-index of small signal excitation   2

* indicates a secondary parameter

Parameter Details

SSTone. Defines which of the large signal tones is treated as small signal. The original N-tone HB analysis is run internally as (N-1) tone HB analysis + small signal analysis. Special elements that refer to the symbolic analysis frequencies, such as PHD-models, are treated so that their symbolic frequencies refer to the HB analysis nonlinear tones. If the schematic has 3 tones [f1,f2,f3] and SSTone=2, the 2-tone HB analysis is done with tone frequencies [f1,f3]. These two tones then define the large signal tones, for example, for a PHD-model with 2-tone data.


This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
