1. Repository description

This project aims to provide a fully open-source alternative to the Open CourseWare Digital Computers 2 Laboratories taught at Politehnica University of Bucharest, during the first semester of the university year 2021-2022.

The official guideline recommends using either the Xilinx ISE or Vivado. Since, both of them are memory heavy (tens of Gb) and closed-source, this repository was born in order to prove a change is possible.

Here is the list of the improvements I brought:

• Makefile with Icarus Simulator support
• Verilator for linting with all warnings managed
  • Some of the members of the PUB team felt like not all Verilator warnings were relevant, for example WIDTH ones in test benches, but I would like to cite other guidelines from Cornell University

    It is a very good idea to control width. [...] Pay attention to warnings

    • But from lab-05 and up I chose to invest my time in better activities than fixing WIDTH warnings
• Correct use of both nonblocking and blocking assignments
• Coding style (as best as I could)
• Improved checkers
• Removed unsynthesizable initial blocks which were not used for simulation purposes only
• Provided information about open-source tools
• Synthesis script (only for some laboratory tasks)

For more information or a syllabus check out the course description page here . This course was taught by Dan-Ștefan Tudose.

I encourage you to watch the online lectures here .

2. Requirements, Usage, and Other projects

Given that this is a follow up project to the Digital Computers 1 repo, all the requirements and usage instruction can be read on it's description. Like this repository, it aims to provide a fully open-source alternative to the Open CourseWare Digital Computers 1 Laboratories (PUB).

3. Acknowledgments

I would like to thank our teaching assistant Ștefan-Dan Ciocîrlan for all his support, this repository would not be possible without him.

Although, I frequently used the pronoun I in this README, I would like to thank Dimitrie David for helping me with it!
