Parameters
• .MODEL
The first line (.MODEL) is the reference to the C-FAS model, where the entity is called
FBLOCK. The other lines are the model parameters.
Note
The .MODEL line is optional. This declaration is not a requirement of Eldo when
referencing embedded Eldo FBLOCK models.
• PARAM:
This keyword precedes the list of parameters, (those shown in brackets are optional). Most
of the options, except for M, IDX_M and NO_DELAY, are specific to the CPF method.
• M=val
Device multiplier parameter, simulating the effect of multiple S-block elements in parallel.
Default value is 1.
• IDX_M=val
Parameter that forces a specific algorithm to be used:
IDX_M=0 specifies the CPF algorithm (default).
IDX_M=1 specifies DSP.
IDX_M=2 specifies SI.
