Raspberry Pi Multi-User Boot Script Setup

This will show how you can setup scripts that will run on bootup of a Raspberry Pi. Any user in the /home/ directory where the name of the user matches the name of their home directory will be able to take advantage of this setup, as well as the root user.

1. Add the following code to the file: /etc/rc.local, but be sure to leave the last line of the file as exit 0

# Startup scripts
## Root
if [ -f /root/startup.sh ]; then

Generating a SystemVerilog Functional Coverage Report Using IMC

1. Be sure you are calling ncverilog with the following flags to enable coverage tracking: -coverage all -covoverwrite

2. In your SystemVerilog program block be sure to call the following SystemVerilog system function: $set_coverage_db_name("database_name");. the "database_name" can be of your choosing

3. After the simulation is complete, the simulator will write a database with the coverage information to the cov_work directory by default

4. Create a file called imc_report.cmd and paste the commands that are below. This file simply tells imc to load the database and which information to save to the report file. Be sure to change the "database_name" so it matches with the parameter in step 2.

Using Sublime Text on Bash on Windows

1. First make sure to install rsub in Bash (follow the tutorial here) and make sure it is in the $PATH environment variable.

2. Create a symlink to the windows executable of Sublime Text so it is the $PATH (I use the ~/bin/ directory that I created). I did this by adding the following lines to my ~/.bashrc because I have found symlinks to be buggy in the Bash environment. This ensures the symlink is re-created each time Bash starts up. (Note: your installation path to the Sublime Text executable may vary)

   $ ln -sfn "$HOME/bin/wsub" "/mnt/d/Program Files/Sublime Text 3/subl.exe"
