Energy estimation for primitive components appears to be broken

[patschmidt2]

Hello, when I use primitive components in my architecture description I find that they do not appear in the ERT that is generated. Here is an example when calling accelergy on the eyeriss_like architecture (which is defined in version 0.3 in my case):

The intmac primitive component does not even show up here. I think that I managed to track this problem down on my end. In primitive_component.py, the actions members are initialized based on the provided component_class. This seems to be defined in accelergy_console.py, line 182 and just uses an empty list for the actions. Since the ERT is generated for each action, this results in primitive components being entirely absent from the ERT file. Is there a way to fix this issue?

I have also noticed that raw_dicts.get_pc_classses().items() returns an empty iterator. I'm not sure if this has something to do with my issue though.

This repo is no longer being actively maintained. I'd recommend using https://github.com/Accelergy-Project/hwcomponents to do your energy estimations if you're having Accelergy errors. Hwcomponents has an easier-to-use energy estimation interface (direct from Python).

I'm using Timeloop, which is how I stumbled over this error. So the recommended way to substitute this seems to be Accelforge with Hwcomponents then, is that right?
