  1. Thank you for your elaborate response. Though I still have to ask a question regarding schedulers. I have a system with n independent DE clusters and one TDF cluster. The latter cluster is implemented inside an hierarchical SystemC module. This module is feeding the TDF cluster with values through DE->TDF input ports. Let's assume that at a time instant all the clusters (DE and TDF) have to execute. I noticed that the TDF cluster is executing first. Even before the SystemC hierarchical module gives an input. In other words the TDF cluster will execute with the old input values because
  2. Hello everybody, I would like to know if AMS and SystemC have two different schedulers. If yes then how do they interact? Moreover i would like to ask how many extensions does SystemC has? Thanks in advance
  3. @Alan I have one more naive question. I should use a channel if and only if I want to simulate the medium of data transmission. In case of an ideal medium, where no data are lost or I have no extra delays in the transmission there is no reason for a channel right?
  4. @Martin 1) I understand your point. However in my case it is important to know or to be able to manipulate the order of execution. That is because the TDF cluster and the the SystemC modules at some point they operate on the same global variables. I understand that this is out of the scope of SystemC however it would be really nice if I could change the execution order by using a functionality of SystemC like wait. In other words if I define a TDF cluster and an isolated SystemC module with the same time step the execution order will be as you said implementation defined. Can I do someth
  5. @Martin Barnasconi First of all thank you for your answer. Though I still have some questions: 1) Let's suppose I have three TDF modules connected to each other with a timestep=10ms. So module A is giving input to module B and module B output is module C input. Apart these modules I have 2 more isolated SystemC modules that are sensitive to a clock with a Period equal of 10ms as well. In such an example the SystemC scheduler will always execute the TDF modules first and then the two SystemC modules. I guess I cannot change this order of execution. For instance can I do something so that
  6. I have a question which probably is quite stupid. I developed a Software in the Loop framework in SytemC. This framework is supposed to call in specific discrete time instants some modules to execute. For instance suppose we have module A and B. Module A has to be executed every 10 ms and Module B every 20 ms. The execution order has to be first A and then B when both modules have to be executed. I am able to do that by having a coordinator module triggered by a clock of 10 ms. Every module ( module A, B and scheduler) are related with an event. Module A and B they look like this: while
  7. Hello to everyone, I would like to ask if it is possible to give a static order for a number of processes in the SystemC Scheduler. Suppose we have 4 processes a,b,c and d. I would like for each clock tick to trigger the processes in the following way: clock tick=1 a,b,c,a,b,c,a,b,c,d,d,d clock tick=2 a,b,c,a,b,c,a,b,c,d,d,d clock tick=3 a,b,c,a,b,c,a,b,c,d,d,d clock tick=4 a,b,c,a,b,c,a,b,c,d,d,d .... Thank you in advance
  8. Hello everyone, I have a folder with many modules. I want to create a configuration file specifying which of those modules to use in my simulation. In the sc_main.cpp, before the simulation starts I would like to open my configuration file, read which modules I would like to open and then create instances, connect their ports etc The configuration file contains all the necessary information as number of ports, type of each port , name of the module, name of the file etc. I can easily create the signals I need but I don't know how I can create the module instance. example of con
  9. Hello everyone, I was wondering if I could run in parallel a number of processes from different modules using multi-threading in SystemC. Take into account that these processes make use of SystemC elements like signal.read etc, from the SystemC library . That means SystemC library should be multi-threading safe. The reason why i want to use multi-threading is to decrease the simulation time, i.e. increase the performance of the simulation. I found this link: http://www.accellera.org/activities/committees/systemc-language/ that states about recent activities on SystemC 2.3.0: " In
  10. Thank you again for your answer Alan. Your idea about using events is nice. I hope it will work in my case. I can't put the whole code in a single module. I am trying to develop a simulation framework for different software applications. So in my application I have several dlls which have to execute at the same time depending on the scheduler, which I am trying to implement with SystemC. The problem is that I might need to execute dll n.1 first and then dll n.2 etc because these dlls they will change values of variables in the SystemC framework that will be read from other dlls at the same sim
  11. Sorry for asking again, but I would like to know if there is any way for module 2 to read the latest value of the signal that module1 has written at the same time ( let's say at the same positive edge).
  12. Thank you for your answer. It's nice that you specify the difference between the signal and the variable. So if I want to be sure that module2 will read the latest value of something I should make sure that this will be a signal and not a global variable. Thank you again Alan.
