This is correct install way
#install scala tool: https://www.scala-sbt.org/download.html
echo "deb https://repo.scala-sbt.org/scalasbt/debian all main" | sudo tee /etc/apt/sources.list.d/sbt.list
echo "deb https://repo.scala-sbt.org/scalasbt/debian /" | sudo tee /etc/apt/sources.list.d/sbt_old.list
curl -sL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo apt-key add
sudo apt update
sudo apt install sbt

I think we should add your exercises as plain Chisel/Scala files with a README.md for the text and not dumping all Jupyter notebook stuff into this repo. There is still the Jupyter repo, we will not delete that one.

In HeapControl.scala, using RegEnable will make full always be true after the first time when heap is full, so the dut cannot deassert full after a remove operation has finished on a previously full dut?

When working through the lab, in lab3 I have a failing test for AccuSpec:

[info] AccuSpec:
[info] Accu
[info] Count15Spec:
[info] - should pass *** FAILED ***
[info]   io_dout=0 (0x0) did not equal expected=3 (0x3) (lines in AccuSpec.scala: 7) (AccuSpec.scala:25)

In the AccuSpec.scala file, there is no dut.clock.step(1) between the last poke and expect. Adding this (see the diff below) made the test case stop failing. I do believe that this is the intended behaviour.

Hi Schoeberl

May I suggest a repository that contains exemplary solutions for the labs in this repository.

Thank you.
