  1. Hi @AmeyaVS I have solved this problem. This runtime error shows up when I try to trace out the wave of sc_fifo. Use the built-in trace() method of sc_fifo instate of sc_trace() solving this problem. #include "system.h" SYSTEM *top = NULL; int sc_main (int argc, char* argv[]) { top = new SYSTEM("top"); sc_trace_file *tr= sc_create_vcd_trace_file("pe"); sc_trace(tr,top->clk_sig,"clock"); top->Input.trace(tr); top->Output.trace(tr); sc_trace(tr,top->rst_sig,"rst"); sc_core::sc_report_handler::set_actions( "/IEEE_Std_1666/deprecated", sc_core::SC_DO_NOTHING ); sc_start(); sc_close_vcd_trace_file(tr); return 0; }
  2. Hi everyone, I have a runtime error when trying to simulate a sc_module An example of my code architecture is presented hereunder, do you see any problem? Here is my error: Error: (E519) wait() is only allowed in SC_THREADs and SC_CTHREADs: in SC_METHODs use next_trigger() instead In file: ../../../src/sysc/kernel/sc_wait.cpp:94 pe.h #include "systemc.h" template<typename IN_T, typename OUT_T> SC_MODULE (pe) { sc_in<bool> clk; sc_in<bool> rst; sc_fifo_in<IN_T> Input; sc_fifo_out<OUT_T> Output; void pe_proc(); SC_HAS_PROCESS(pe); pe(sc_module_name name_, int p_time_) : sc_module(name_), p_time(p_time_) { SC_CTHREAD(pe_proc, clk.pos()); reset_signal_is(rst, true); } private: int p_time; }; template<typename IN_T, typename OUT_T> void pe<IN_T, OUT_T>::pe_proc(void) { IN_T in_val; OUT_T out_val; // Reset code // Reset internal variables in_val = 0; out_val = 0; // Reset outputs wait(); while (true) { // Read inputs in_val = Input.read(); // Algorithm code for (int i = 0; i < p_time; i++) { wait(); } // write outputs out_val = (OUT_T) in_val; Output.write(out_val); } }
