  1. C:\Users\...\systemc\src\sysc\packages\qt\md\iX86_64.s: Assembler messages: C:\Users\...\systemc\src\sysc\packages\qt\md\iX86_64.s:77: Error: junk at end of line, first unrecognized character is `-' mingw32-make.exe[2]: *** [...\systemc\src\CMakeFiles\systemc.dir\build.make:1266: .../systemc/src/CMakeFiles/systemc.dir/sysc/packages/qt/md/iX86_64.s.obj] Error 1 mingw32-make.exe[1]: *** [CMakeFiles\Makefile2:1006: .../systemc/src/CMakeFiles/systemc.dir/all] Error 2 mingw32-make.exe: *** [Makefile:129: all] Error 2 SystemC was build with CMAKE in the context of a CMAKE project.

  2. So I can build sucessfully SystemC with QtCreator under Windows with MinGW that is provided with QtCreator using CMake. So it should now be pretty save that the SystemC compiling process is correct. However, when I use the SystemC Library withing one of my projects, I have again this error: C:/<...>/Qt/Tools/mingw530_32/bin/mingw32-make -f Makefile.Release mingw32-make[1]: Entering directory 'C:/<...>/Programming/SCVP.artifacts/build-tlm_at_1-Desktop_Qt_5_10_0_MinGW_32bit-Release' g++ -Wl,-s -Wl,-subsystem,console -mthreads -o release\tlm_at_1.exe release/main.o release/
  3. I tried that before and it was not working. However, now its working thanks for the hint! Regards Matthias
  4. When I start this, cmake uses MSVC for compiling, how can i force it to use MinGW? -DCMAKE_CXX_COMPILER -DCMAKE_CC_COMPILER Seems to be ignored

  6. Hi Philipp, sorry my question was misleading. Why the transition from nb_transport_bw/BEGIN_RESP to TLM_COMPLETED has been removed from The OSCI TLM LRM (2009) to the Systemc 1666 LRM (2011). See attached Picture:
  7. Why has the path from nb_transport_bw/BEGIN_RESP to TLM_COMPLETED has been removed from The OSCI TLM LRM (2009) to the Systemc 1666 LRM (2011).
  8. I found a solution: https://github.com/tukl-msd/SCVP.artifacts/tree/master/kpn_artificial_deadlock Indeed it depends on the way how SystemC schedules the processes. Note that it may behave differently w.r.t. scheduling and therefore also w.r.t. FIFO sizes If you call wait(SC_ZERO_TIME) in between.
  9. Dear Philipp, That is unfortunately not the case :( . When a process reads from a queue, the read is blocking. If the queue is empty, then the process will suspend until there is enough data in the queue. This allows even data dependent control flow or control flow depending on internal variables: process f(in int u, in int v, out int w) { int i; bool b = true; while (true) { i = b ? wait(u) : wait(w); printf("%i\n", i); send(i, w); b = !b; } } This is an example form Kahn's original paper in a C syntax. Alternately u and v is read. So
  10. Hey, Kahn Process Networks are defined by the usage of unbounded FIFOs with blocking reads and non-blocking writes. I read on several sources that KPN with bounded FIFO size (i.e. blocking read and blocking write) can be implemented with SystemC (e.g. Grötker et al). It seams that the event based scheduler in SystemC behaves different like data-driven scheduler or a demand-driven for KPNs. I simulated the networks of Park's Dissertation shown on page 36 and 42 which should end up in an artificial deadlock (deadlock which occurs because of blocking write). A global artificial
  11. Hey, is there a way or mechanism such that a cout or printf statement in an SC_METHOD is delayed to the last delta cycle before the time advances? Similar to the VCD traces? Such that only the last stable value is printed to the terminal. Regards Matthias
