SpinalHDL labs

There is the list of RTL labs :

  • Counter : src/main/scala/workshop/counter
  • PWM with APB : src/main/scala/workshop/pwm
  • UART : src/main/scala/workshop/uart
  • Prime : src/main/scala/workshop/prime
  • Function : src/main/scala/workshop/function
  • Apb3Decoder : src/main/scala/workshop/apb3decoder
  • Timer with BusSlaveFactory : src/main/scala/workshop/timer
  • Blackbox and Clockdomain : src/main/scala/workshop/blackboxAndClock
  • Stream : src/main/scala/workshop/stream
  • Mandelbrot : src/main/scala/workshop/mandelbrot
  • UDP : src/main/scala/workshop/udp
  • WavePlayer : src/main/scala/workshop/waveplayer

In each labs, there is an assets folder which contain a starting template and a solution.
In each labs, there is an spec.md which give basics of the lab. (You can get the Intellij plugin to read it in the IDE)
In the case a lab specification isn't clear, you can find in waves.tar.gz the corresponding working waves.
Those labs make the assumption that you are already comfortable with standards HDL.

Generate your RTL

For each labs, you will find a scala main which will generate your RTL.

For example, to run the CounterMain by using SBT, you can do as following in the root folder of this repository :

sbt
runMain workshop.counter.CounterMain

# Run again
runMain workshop.counter.CounterMain

# Run again
runMain workshop.counter.CounterMain

Or in a single (But slower) command :

sbt "runMain workshop.counter.CounterMain"

All generated RTL will be in root_of_this_repository/rtl.

Test your RTL

For each labs, you will find an automated regression suite in src/test/scala/workshop/xxx

For example, to run the CounterTester regression by using SBT, you can do as following in the root folder of this repository :

sbt
testOnly *.CounterTester

# To test again
testOnly *.CounterTester

# To test again
testOnly *.CounterTester

Or in a single (But slower) command :

sbt "testOnly *.CounterTester"

Note : Each tester regenerate the hardware, you don't need to do it manually.

All simulation waves files will be written in root_of_this_repository/waves in the VCD format.

SpinalSim labs

There is the list of SpinalSim labs :

  • SimCounter : src/main/python/workshop/simCounter
  • SimStreamJoinFork : src/main/python/workshop/simStreamJoinFork

In each labs, there is an assets folder which contain a starting template and a solution.
In each labs, there is an spec.md which give basics of the lab. (You can get the Intellij plugin to read it in the IDE)
For SpinalSim, the simulation waves are located in the simWorkspace folder.

Cocotb labs

There is the list of Cocotb labs :

  • Counter with cocotb : src/test/python/workshop/counter
  • FIFO with cocotb : src/test/python/workshop/fifo

To run cocotb labs, you have to run make in the testbench folder.

Minimum requirements

Those labs use various tools to generate and verify the hardware :

For the first row of labs, you don't need cocotb/python stuffs.

There is how to setup by command line a Debian distribution :

# JAVA 8
sudo add-apt-repository -y ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk -y
sudo update-alternatives --config java
sudo update-alternatives --config javac

# SBT
echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt -y

# Verilator
sudo apt-get install git make autoconf g++ flex bison -y  # First time prerequisites
git clone http://git.veripool.org/git/verilator   # Only first time

unsetenv VERILATOR_ROOT  # For csh; ignore error if on bash
unset VERILATOR_ROOT  # For bash
cd verilator
git pull        # Make sure we're up-to-date
git tag         # See what versions exist
#git checkout HEAD                 # Use HEAD development version
#git checkout verilator_{version}  # Switch to specified version
autoconf        # Create ./configure script
./configure
make -j$(nproc)
sudo make install
cd ..

# iverilog (debian package 9.7 contain bugs)
