problems during Step 5 of the Quickstart Guide: Run cocotb simulation on your design

[onestwob]

Hi,

I have encountered some problems during Step 5 of the Quickstart Guide: Run cocotb simulation on your design.

To run the gen_gpio_defaults.py script to generate caravel_core.v, I ran the following command:

python3 $CARAVEL_ROOT/scripts/gen_gpio_defaults.py

The error log was generated as follows:
...
Step 2: Modify top-level layouts to use the specified defaults.
Traceback (most recent call last):
File "/home/onestwob/projects/caravel_soc/caravel_user_project/caravel/scripts/gen_gpio_defaults.py", line 342, in
with open(caravel_path + '/mag/caravel_core.mag', 'r') as ifile:
FileNotFoundError: [Errno 2] No such file or directory: '/home/onestwob/projects/caravel_soc/caravel_user_project/caravel/mag/caravel_core.mag'

I ignored this error and successfully ran the RTL simulation. However, during the GL simulation, the same error occurred again.

The error seems to occur due to the absence of caravel_core.mag. I looked into the previous issues, but I couldn't find a solution to it.

Could you please help me with this issue?
