    Build error with 2.3.2

    Hello @katang, Did you set the CXX_STANDARD in CMakeLists.txt? Here is an example: https://github.com/AmeyaVS/SystemC_ramblings/blob/master/src/01_SystemCTest/CMakeLists.txt Also while building SystemC 2.3.2 did you configure it with -DCMAKE_CXX_STANDARD=11? Hope it helps. Regards, Ameya Vikram Singh

    SystemC code running with testbench

    Hello @ssingh.codesupport, There are multiple issues here. It would really good if you can go through the following discussions and develop an understanding about the SystemC simulation workflow. In-case you still have questions you can post you queries here. Hope it helps. Regards, Ameya Vikram Singh

    A void value confusion

    Hello @katang, The compiler message is quite right as mentioned by @Eyck. The Compiler sees the code something like this: void Dendrit_Set(int index, int value) { *(mNeuron->dendrit[index].write(value)); } Basically the operator precedence is at play here(refer here for more details). Compiler sees that you are trying to dereference a void type, since the write method of the sc_signal returns void. Hope it helps. Best Regards, Ameya Vikram Singh

    A SystemC installl problem on Ubuntu

    Hello @katang, Is there a specific reason for using SystemC 2.3.1 release? This issue has already been fixed in the SystemC 2.3.2 release as mentioned by @maehne. Best Regards, Ameya Vikram Singh

    make check return fail

    Hello @LookBad, Sorry, I don't have a macOS environment readily available with me. Maybe someone else might be able to help you with that, or better would be if you could use a Linux VM for exploration. Regards, Ameya Vikram Singh

    How to update the signal writing with same value

    Hello @SANDESH M K, You are probably looking for sc_buffer<T>. sc_buffer will generate the event notification for every write performed. Hope it helps. Regards, Ameya Vikram Singh

    make check return fail

    Hello @LookBad, Can you provide some environment details? e.g.: OS, Compiler version etc. Regards, Ameya Vikram Singh
  10. Hello @YashJ, It is expected behavior. Here is a brief explanation: //... // Find the inline comments: while(true){ wait(); //< Wait for default event sensitivty(static sensitive event!). In you case it is in.value_changed() cout<<"\nIN = "<<in.read()<<" TIME" <<sc_time_stamp()<<endl; inter.write(in.read()); //< Write to the inter signal -> which means schedule and event for updating the sc_signal. cout<<"\nInter before wait= "<<inter.read()<<endl; wait(10,SC_NS); //< Relinquish control to the SystemC scheduler -> perform evaluate and update phase for all event scheduled. (Change sensitivity to dynamic scheduled after 10 ns) out.write(inter.read()); //< inter has the new value assigned at 3 lines before this statement. cout<<"\nInter after wait= "<<inter.read()<<endl; cout<<"\nOUT = "<<out.read()<<" TIME" <<sc_time_stamp()<<endl; cout<<"\nIN when outed = "<<in.read()<<endl; } ///.... Hope it helps. Regards, Ameya Vikram Singh

    SystemC basic tutorial and examples

    Hello @ajinkya_bankar, Can you let us know what all have you tried? and also, what is it you are looking at SystemC for RTL design or high-level modelling? Most of the examples though dated, require minimal changes to be fully functional, and you can quickly update them to Did you look at examples directory within the SystemC open source implementation available here. If you looking at SystemC RTL design then probably this book: SystemC Primer would be good though also a bit dated. In-case you are looking for using SystemC for high-level modelling your a find these references to be quite useful: SystemC: From Ground Up (Second Edition) SystemC Language Reference Manual(LRM) Hope these resources help. Regards, Ameya Vikram Singh
  12. Hello @sumit_tuwien, You can turn off the G++ extensions using the CMake command-line option: # Enable C++11 compilation flag # -DCMAKE_CXX_STANDARD=11 # Disable C++ Compiler Extensions # -DCMAKE_CXX_EXTENSIONS=OFF cmake -DCMAKE_CXX_STANDARD=11 -DCMAKE_CXX_EXTENSIONS=OFF -DCMAKE_INSTALL_PREFIX=<Path to install location> .. You can find a reference here. Can you also list the version and platform information of the tools you are using (clang, CMake, etc.)? Hope it helps. Regards, Ameya Vikram Singh

    fifo example

    Hello @veeresh k, There are multiple issues in the sample code provided by you. Here are the heavily modified version: // main.cpp #include<systemc> //< Notice not systemc.h #include"head1.h" #include"head2.h" int sc_main(int argc, char* argv[]) { sc_core::sc_fifo<int> fifo(10); //< sc_core namespace specifier writer w("writer"); reader r("reader"); w.out(fifo); r.in(fifo); sc_start(1000, sc_core::SC_NS); //< Run simulation for a limited time since no stopping condition are provided upfront. Also time is also specified in sc_core namespace. return 0; } //head1.h // Notice the HEADER GUARD #ifndef HEAD1_H_ #define HEAD1_H_ // Changed the header file to systemc instead of systemc.h #include<systemc> SC_MODULE(reader) { // sc_fifo_in_if is a abstract class from which you cannot create an object. // sc_fifo_in is derived from the above class which actually implements the read method. sc_core::sc_fifo_in<int> in; void roperation() { int val; while (true) { wait(10, sc_core::SC_NS); // Time unit is defined in sc_core namespace. for (int i = 0; i <= 15; i++) { in.read(val); std::cout << val << std::endl; //< when using the systemc header you need to specify the std namespace. // Or you can use the statement after including all the header files: // using namespace std } } std::cout << "Availaible : " << in.num_available() << std::endl; //< Instead of num available it is num_available //< when using the systemc header you need to specify the std namespace. // Or you can use the statement after including all the header files: // using namespace std } SC_CTOR(reader) //< Your code mentions here writer the constructor name should be same as the class name. { SC_THREAD(roperation); //< Your code mentions woperation } }; #endif // HEAD1_H_ //head2.h // Refer the head1.h for similar details #ifndef HEAD2_H_ #define HEAD2_H_ #include<systemc> SC_MODULE(writer) { // Refer the head1.h for similar details sc_core::sc_fifo_out<int> out; void woperation() { int val = 0; while (true) { wait(10, sc_core::SC_NS); for (int i = 0; i <= 20; i++) { out.write(val++); } } } SC_CTOR(writer) { SC_THREAD(woperation); } }; #endif // HEAD2_H_ Here is a minimal makefile for building the example: CC=gcc CXX=g++ CXX_FLAGS= -g3 -Wall -c all: main.exe main.exe: main.o ${CXX} $< -o $@ -L${SYSTEMC_HOME}/lib-linux64 -L${SYSTEMC_HOME}/lib -lsystemc main.o: main.cpp head1.h head2.h ${CXX} ${CXX_FLAGS} -I${SYSTEMC_HOME}/include -o $@ $< clean: rm -rf main.o main.exe Note: For reference of the sc_fifo_in/out_if classes see here.

    Systemc 2.3.2 Changes

    Hello @sumit_tuwien, You can find the necessary details from the SystemC sources. You can look into these files for more details: RELEASENOTES README NOTICE You can also compare the RELEASENOTES from previous releases. Regards, Ameya Vikram Singh
  15. Hello @vasu_c, Can you let us know what platform you are using for the AArch64 build? and also, if possible the ABI specifications of the GCC compiler as well? Thanks and Regards, Ameya Vikram Singh
