Hi there,
I'm trying to create a SystemC top level module by instantiating several modules.
The top-level-module has e.g. a sc_uint-type interface with 8bit, the instantiated modules have bool-interfaces. So I create 8 instances and want to connect the bool port of instance 0 to bit zero of the top-level vector port, instance 1 to bit 1 of the vector...and so on.
I want a simmilar thing with sc_uint<128> port of the instances...the top-level module got a 1024 bit sc_uint port.
Here a snip-set from the top-level module:
The instantiated module:
With cadence ncsim its not compiling....it complains:
For part select a similar error occurs.
Changing from bool to sc_uint<1> makes also no difference.
Has anyone an idea how to solve this? :?:
Thank you !

Code:
SC_MODULE(stim_top){
sc_in <bool> clk_i;
sc_in <bool> rst_n_i;
sc_out <sc_uint<8> fifo_write_en;
sc_out <sc_uint<8* 128> fifo_write_data;
...
stim_0.fifo_write_en(fifo_write_en[0]); // bit select
stim_1.fifo_write_en(fifo_write_en[1]);
...
stim_0.fifo_write_data(lfifo_write_data((1+0)*128-1,0*128)); //part select
stim_1.fifo_write_data(fifo_write_data((1+1)*128-1,1*128));
The instantiated module:
Code:
SC_MODULE(stim){
sc_in <bool> clk_i;
sc_in <bool> rst_n_i;
sc_out <sc_bool > fifo_write_en;
sc_out <sc_uint< 128> > fifo_write_data;
...
With cadence ncsim its not compiling....it complains:
Code:
no instance of overloaded function
"sc_core::sc_out<T>::operator() [with T=bool]" matches
the argument list
argument types are: (
sc_core::sc_signal_inout_if<sc_dt::sc_uint<16>> *)
