  1. Hi,

     

    I work on a simple System on Chip. I have a cpu, a bus and a ram.

     

    When I compile the following code I got a error message.

     

    The code is:

    #include <stdlib.h>
    #include <stdio.h>
    #include <string.h>
    
    #include "systemc.h"
    //Use an OVP Microblaze 8.2 processor model
    #include "xilinx.ovpworld.org/processor/microblaze/1.0/tlm2.0/microblaze_V8_20.igen.hpp"
    #include "ovpworld.org/modelSupport/tlmPlatform/1.0/tlm2.0/tlmPlatform.hpp"
    //Use Memory
    #include "ovpworld.org/memory/ram/1.0/tlm2.0/tlmMemory.hpp"
    //Use Bus
    #include "ovpworld.org/modelSupport/tlmDecoder/1.0/tlm2.0/tlmDecoder.hpp"
    
    icmAttrListObject *attrsForcpu1()
    {
       icmAttrListObject *userAttrs = new icmAttrListObject;
       return userAttrs;
    }
    
    int sc_main(int argc, char *argv[0])
    {
        //Instantiate OVP platform
         icmTLMPlatform *platform = new icmTLMPlatform("icm", ICM_VERBOSE | ICM_STOP_ON_CTRLC| ICM_ENABLE_IMPERAS_INTERCEPTS);
      
        //Instantiate RAM
        ram *speicher = new ram("speicher","sp1", 0x100000);    
    
        //Instantiate Bus     decoder<NR_OF_INITIATORS,NR_OF_TARGETS>
        decoder<1,1> *bus = new decoder<1,1>("bus");
    
        //Instantiate the processor
        microblaze_V8_20 *core = new microblaze_V8_20("core", 0, ICM_ATTR_DEFAULT, attrsForcpu1());
    
        //Bind CPU with Bus
        core->INSTRUCTION.socket(bus->target_socket[0]);
        core->DATA.socket(bus->target_socket[1]);
    
        //Bind Bus with RAM
        bus->initiator_socket[1](speicher->sp1);
        bus->setDecode(1, 0x00200000, 0x002fffff);
         
        // Load application 
        core->loadLocalMemory("application.MICROBLAZE.elf", 1, 1, 1);
    
        //Start and stop the simulation
        sc_core::sc_start();
    
        sc_core::sc_stop();
    
    
        //Deallocate objects
        delete core;
        delete platform;
    
        return 0;
    }
    
    

    The error message on the console is:

     

    make -f $IMPERAS_HOME/ImperasLib/so/buildutils/Makefile.TLM.platform PLATFORM=mb_tlm

    I don't know what is wrong with TLM.

    Could anybody help me?

     

    Thx

  2. Hi Philipp,

     

    I thank you a lot for your quickly answer.

     

    I configured my SystemC configure options by invoking ../configure --disable-async-updates --prefix=/usr/local/systemc-2.3.0.

    Now I don't have linking problems anymore.

     

     

    Actually I don't need the pthread functionality. But for the case I need it: Do I only have to write SYSTEMC_CXX_FLAGS=-pthread in my Makefile?

     

    Here are the error message I got before I disabled the "async_request_update" feature:

     

    make  -f $IMPERAS_HOME/ImperasLib/source/buildutils/Makefile.TLM.platform Platform= PLATFORM=OVPsim_microblaze_tlm2.0

    g++ -o platform.Linux32.exe Build/Linux32/usr/local/platform.o -L/Imperas.20130315/bin/Linux32 -lRuntimeLoader /usr/local/systemc-2.3.0/lib-linux/libsystemc.a -m32 Build/Linux32/tlm/tlmSupport.a

    sc_prim_channel.cpp:(.text._ZN7sc_core13sc_host_mutex7trylockEv[sc_core::sc_host_mutex::trylock()]+0x1c): undefined reference to `pthread_mutex_trylock'
    collect2: ld return 1
    make: *** [platform.Linux32.exe] Error 1

     

     

    Thank you once again.

  3. Hi,

     

    I have same problem. I set SYSTEMC_CXX_FLAGS with export SYSTEMC_CXX_FLAGS=-pthread. After that I tried to compile it again and I got the same error.

    I don't know what I should do. Can you help me, please?

    By the way how can I add "--disable-async-updates" to my SystemC configure options.

     

     

    Thank you in advance.

  4. Hello everyone,

     

    I’m new in systemc and in this forum.

     

    I successfully downloaded and installed systemc-2.3.0 on MSVC-2010 (Windows 7)

     

    I can compile and run the examples.

    BUT when I write an own program it doesn’t work.

    For example I wrote this simple program.

     

    #include "systemc.h"#define WIDTH  4
    SC_MODULE(adder) {
       sc_in<sc_uint<WIDTH> > a, b;     sc_out<sc_uint<WIDTH> > sum;
      void do_add() {      sum.write(a.read() + b.read())  }
      SC_CTOR(adder)       {    SC_METHOD(do_add);       sensitive << a << b;  }
    };

     

    systemc.lib(sc_main_main.obj) : error LNK2019: unresolved external symbol
    > _sc_main referenced in function _sc_elab_and_sim
    > Debug/addieren.exe : fatal error LNK1120: 1 unresolved externals
     

    It seems that the compiler can’t find systemc.lib, but I have add additional libraries in the properties and set the environment variable.

    I checked it many times but I always got the above-mentioned messages.

     

    Can you help me?

     

    Thanks in advance.
