Visualizer for Pipelined CPU's

[klanmiko]

This visualizer was written in scala-swing and the goal is to display the modules used in the pipelined CPU design and their relative location between the pipeline registers. The visualization should reflect the value of I/O on the modules and update every cycle.

Features:

• Designed with an MVC architecture based on a simplified circuit module and description of the pipelined CPU.
• Loads LowFIRRTL through some AST parsing
• Automatically places instances of modules to their correct pipeline register by running a DFS on the node graph to find modules connected to each pipeline register
• Uses Treadle's peek() call to load values at ports.

Very cool! I'm super excited to use this next quarter!

You should make sure your name is attached to this with more than just the commit message. I would suggest adding an "about" dialog or putting "By Kaelan..." in one of the bottom corners.

This change should be reverted :)

Looks like a couple of files got added accidentally on this commit :).

I just tried to run this and got the following error:

> singularity exec library://jlowepower/default/dinocpu sbt "runMain dinocpu.visualize multiply.riscv" 
java.lang.UnsatisfiedLinkError: /usr/local/openjdk-8/jre/lib/amd64/libawt_xawt.so: libXext.so.6: cannot open shared object file: No such file or directory

It looks like I might need to update the singularity container to have some other dependency installed. Do you know what the dependencies are for this?

I figured it out. The following needs to be added to the dinocpu.def:

%post
    curl -L -o sbt-1.3.4.deb https://dl.bintray.com/sbt/debian/sbt-1.3.4.deb && \
    dpkg -i sbt-1.3.4.deb && \
    rm sbt-1.3.4.deb && \
    apt-get update -y && \
    apt-get install sbt libxext6 libfontconfig1 libxrender1 libxtst6 -y

Ah. I never tested in the singularity container as I have sbt on my local development environment. I guess the old container didn't have awt and dependencies.

LGTM! There's a lot that could be improved, but it's a really solid addition. Thanks!
