Respected Sir,
Can you please explain little bit about _driver_sends, scoreboard, monitor and put/get? How they are related to design modules? And little bit guide to implement them.

Testplan

Respected Sir,
Do I have to share the test plan as well?

What do you mean by datapath?

Configuration Interface: Coding Test Assignment

Respected Sir,
Can you please tell me a little bit about the configuration interface? It would be more useful if you could explain me a data transfer from all three interfaces.
Have a great day ahead!

PEP517 Error while installing cocotb package

Building wheel for cocotb (PEP 517) ... error
ERROR: Failed building wheel for cocotb
Failed to build cocotb
ERROR: Could not build wheels for cocotb which use PEP 517 and cannot be installed directly

I tried updating python and other packages. Also I tried to install the development version, the same error seems to pop up.
I have installed python 3.9 version on Windows 10.

PS: Had some issues with versions of MSVC for installing cocotb. Works after reinstallation
