Yes, I understand that. DPRINTF and std::cout work fine with me too. But i'm sorry, my question wasn't about using DPRINTF, I already used it before and it worked fine. My question is about the flit inside the Mesh_XY routing, i want to debug and print the flits or packets to trace it during the

[gem5-users] Re: gem5 / garnet / simple custom routing

Yes, when I simulate the topology with the default weight-based routing algorithm it's working fine. and the simulation ends when the network tester completes simCycles successfully. Actually I can't tell exactly when the segmentation fault happens, but it's happening the moment when I hit the

[gem5-users] garnet - garnet synthetic traffic - Mesh_XY routing algorithm

Hi, for my research I'm trying to implement a custom routing algorithm in gem5/garnet. Someone from the mailing list recommended that I should go for the Mexh_XY routing algorithm to understand how it's working. The mesh topology i'm using contains only 4 cpus and 4 dirs and number of mesh rows
