How to set scp output

[alpha-beta-user]

This is a great work!

SCP_DEBUG(()) << "ContainerBase Constructor";

based on the above code, I want to know why there is no output on the terminal. or the std::cout.

thanks for your attention!

Hi !
So yes, you can choose which output you want for any SystemC models.
For example if you look the lua file you will see many models in it, you can print the log of any of them or even all of them.
By default the log of the platform are disabled:

qbox/platforms/src/main.cc

Line 59 in 2259081

cci::cci_param<int> p_log_level{ "log_level", 0, "Default log level", cci::CCI_ABSOLUTE_NAME, orig };

If you change the value of this CCI parameter, it will change the log of the entire platform, you will have the logs for each models.

Instead of changing the value in the source code, you can do it directly in the command line, something like that:

./platforms/platforms-vp -p platform.log_level=5 -l ../platforms/ubuntu/conf_aarch64.lua

If you want specific models, you just need to add the name of the models between "platform" and "log_level", i.e:

./platforms/platforms-vp -p platform.<name_of_the_model>.log_level=5 -l ../platforms/ubuntu/conf_aarch64.lua

./platforms/platforms-vp -p platform.gic_0.log_level=5 -l ../platforms/ubuntu/conf_aarch64.lua

The value of log_level can change, 0 it will print nothing, 1,2 you will have the SCP_ERROR, 3 you will have SCP_WARN, 4 you will have SCP_INFO, 5 you will have SCP_DEBUG and more than 5 you will have SCP_TRACE.
