Hi can somebody help me with this error? 

Error: SystemC-AMS: A sca_tdf::sca_module ( dut ) can't have child: sca_tdf::sca_module( dut.sine )  see LRM clause 4.1

This is the code taken directly from the SystemC-AMS User Manual

Replace SCA_TDF_MODULE with SC_MODULE and it should work. Your module instantiates other modules to interconnect them. A TDF module is always a primitive module without any inner structure in form of submodules. Instead, it serves to describe the timed dataflow behaviour using the various TDF callbacks.

Regarding this claim: The code snipped in Example 7.2 on page 87 of the SystemC-AMS User Manual published in January 2020 is correctly using SC_MODULE.
