Using GDB in simulation runs to debug C-code

When we run simulations with C-models (along with RTL and SV-UVM TB ) we might want to debug the C-code to identify issues.

Here is a list of commands for GDB ( for VCS )

1. gdb <SIMV absolute path>.
2. break <File_name>:<Line_number>
3. run <Simulation command line arguments>

These will allow you to to run the simulation until the debug point.

1. For executing line by line we can use <next>
2. For step, we can use <step>
3. To continue till next occurrence of  break point use <continue >
4. To print any variable with (print <var>)
