Constant signal in LSF module

[AlexSax]

Hello everyone,

I am implementing a module using LSF primitives and I need to add a signal to a constant value (a parameter of such module).

The first solution that came to my mind was to use a sca_tdf_source element but then I would need a tdf_module only for this constant value.

Then I thought of forcing a sca_lsf::sca_source element to provide a constant source signal as follows:

Vref("Vref", Vref_, 0.0, Vref_, 0.0, M_PI/2)

where Vref_ is the constant value.

 

Could it work this way?

 

Best regards,

Alessandro

Indeed, you can use an sca_lsf::sca_source to generate your constant reference signal. However, you have to use the initial_value and offset parameters instead of the amplitude:

sca_lsf::sca_source Vref("Vref", Vref_, Vref_);

You don't have to provide all arguments to the sca_lsf::sca_source constructor, as they are defaulted to zero. For more details, see clause 4.2.1.12.2 of the SystemC AMS 2.0 LRM.

You're right Torsten, thank you very much!
