    Thank you, very useful list.

    Do you know any tool that generates synthesizable HDL code (e.g. like Atlas) ?

    Regards.

  2. suman says:

  5. ali says:

    hi! nice work .
    i want to simulate noc by keeping different sizes of input buffers of the routers in a single simulation . can someone help me?

    • fargoscape says:

      Ali,
      you can help yourself by selecting an NoC simulator and modifying its source code to do exactly what you wanted; it should be straightforward to make changes such that input buffer sizes are what you want.

  6. Amin says:

    Hi, thank you for your fantastic gathering. Isn’t any simulator available for Wireless NoC?

  7. zeekhan says:

    I need NOC mapping simulator for energy minimization.plz anyone that can help me. thanks

  8. Vinu says:

    Hi,
    I am looking for the download file for PheonixSim (as per their install guide) but could not find it on their website. Any help would be appreciated.

    Thanks

    • fargoscape says:

      I know someone who contacted the authors about the source code. They said that the student(s) who worked on it graduated and no one has the code now…

      • Vinu says:

        Yes, I contacted the group behind PheonixSim and they said that it is undergoing drastic changes before version 2 is released and they recommended me to use MIT-DSENT in the meantime. However, when I asked them if I can get the original code, I did not get any reply.

  9. zeekhan says:

    I have downloaded nocmap1.2, but it gives errors when I run the makefile on Ubuntu g++ compiler. I need help to run the simulator.

  10. Parnian Mk says:

    Hi, I have a network with 400,000 nodes. How do I choose which simulator is best?

  11. anmol says:

    hi. I am unable to run noxim_explorer with traffic type shuffle and butterfly. I get the following error Output file ./.noxim_explorer.tmp corrupted
    when the traffic is changed to random or transpose1 in the sim.cfg, noxim_explorer works fine.

    • deepthi says:

      Hi anmol,

      even i am facing similar error,
      Error: Output file ./.noxim_explorer.tmp corrupted
      were you able to get rid of this error..??
      can you please sare with me if you have any update on the same

      Thanks and Best Regards,
      Deepthi

  13. Guys,
    Thanks a lot for such an article, although it’s 2 years old but still great,
    A question: is there any Open-source simulator of those claimed to simulate up to 1000-core but it is offer a full-system simulation means to run any unmodified OS on it so just to port the OS to the simulator and then have it running over 1000-cores?
    I have been looking for such a thing but seriously I can’t find a good answer until now?

    Cheers,
    Abdo

  14. laure says:

    Hi, I want to know if someone has an idea about noctweak simulator?Is it easy to manipulate it and can we have some modications or addition to the code, for example if we want to add a new type of scheduler?
    Thank you for you response.

  15. Babak Aghaei says:

    which NoC simulator is best for NoC testing strategies?

    • It would depend on a what you want to test and what a specific simulator supports. For example, if your aim is to learn the basics and start out on a NoC learning curve, then I would recommend Noxim or Booksim. If you wish to do something more complicated, then you should look out for something like garnet/hornet etc where some modifications might be needed. There is no one simulator that can be considered as a complete solution or a standard. So, you be your own judge.

      • Babak Aghaei says:

        Dear mohan
        thank alot for your kindly reply.
        my interesting field is testing and fault tolerant of NoC. so, now i want start studies.
        my major aim is increasing fault tolerent of NoC, If I could find a simulator.
        plz if possible guide me!
        Is there simulator that evaluates noc reliability?
        Is there simulator that evaluates noc fault tolerant?
        Is there simulator that evaluates noc testability?

  16. Ramesh says:

    which noc simulator is better for performance evalaution of different noc topologies on the basis of throughput,power,area,delay parameters and application mapping is also possible on that.
    plz suggest the simulator for this asap.
    thanks

    • babak says:

      I think you must experiment of nocTweak simulator, this is very good for area evaluation and other your favorite parameters.

  17. Ramesh says:

    Babak, Thanks a lot ,
    Is there any possibility to do the same performance evaluation writing code in vhdl,verilog and implement it on any FPGA Board .Please reply soon.
    Thanks

    • Babak says:

      hi
      i dont think vhdl and verilog language have any component that evaluate perfomance, but you can do this with other tools like quartus and ISE xilinx and so on

      • Ramesh says:

        Thanks for reply , U said s quite ok but how to proceed for that any references any guidance,as if we use quartus or xilinx ISE then HDL(Verilog/VHDL) must.

      • Ramesh says:

        Plz guide me regarding noctweak simulator how to install it and run it .any help
        reply soon

  18. jiumeilema says:

    Hi all:
    I need a 3D noc simulator for mapping Algorithms, Which NoC simulator is best.

  19. maverick says:

    Any wireless NoC simulator available???

    • Hemanta Kumar Mondal says:

      In case of wireless emerging interconnects, you have to modify the wired NoC simulator as per your WNoC topology. You should change the source code carefully. If you want full system simulation with wireless interconnect, You can use Topaz instead of Garnet (Stop updating some time back), Gem5 and Ruby network tester. Integration of these tools are already available in https://code.google.com/p/tpzsimul /wiki/GEM5Integration#Step_3:_Use_TOPAZ_within_GEM5_Ruby_Network_tester

      Whatever you want to add like WNoC topology, routing or modify, do with topaz then run the make file. Then you can able to see the expected results in gem5/ruby.stats file.

      I think this may help you.

  23. mostafa says:

    Hi all. I need a guide for booksim installation & setup file
    please help me 🙂

    • Fiona Song says:

      Hello mostafa, did u install and build the booksim successfully? I am a new one of booksim2.0 and i also met some problems building it. It said i should modify the makefile to give the tool the right path, i did modify the first two lines, and when i make it there was no errors. But when i run ./booksim [configfile], it said could not open configuration file. I don’t know what was wrong. Maybe i modify the makefile in a wrong way? So do u know how to build the simulator in the right way?

      Thanks.

  24. B.abdelwaheb says:

  33. Kumar says:

    Dear Sir, Thanks for your complete information.
    My question: How to measure the Power of NoC(Booksim) by McPAT. It is mentioned in literature that run time statistics of Booksim should be passed to McPAT. Would you specify what run time statistics should be taken from booksim simulation and pass it to McPAT for measuring the power. Please provide me any other information regarding measuring the power of Noc by using McPAT.
