#[fit] Software
You may use what ever you want, but exercises and project have been developed using AIM-Spice, ngspice, iverilog, and GKTwave on Ubuntu linux 20.10
SPICE
- AIM-Spice aimspice.com (Used for exercises)
- NGSpice ngspice , version 34 (Recommended for project)
SystemVerilog
- iverilog Icarus Verilog, version v11_0
- gtkwave GTKWave, version 3.3.104
- ( yosys Yosys, version 0.9 )
The software can be installed on Windows, Mac, and Linux
| Pros | Cons |
|---|---|
| Once it's running, then it's easy | Take time to install |
| Compile from source | |
| No support from us on installing |
| Pros | Cons |
|---|---|
| I've tested with login.ansatt.ntnu.no | GUI windows require a bit of work |
| Similar to real world (desktop + server) | Online |
ssh to login.stud.ntnu.no, run
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/wulffern/dicex/main/ubuntu_install.sh)"Connect to login from a mac/linux so you get GUI also
ssh -c aes128-ctr -YC -o "ForwardX11Timeout 4W" <username>@login.stud.ntnu.noRun Ubuntu linux on your PC via docker and use a VNC client to connect
| Pros | Cons |
|---|---|
| If it works, it's easy | Complex, so maybe there are issues |
| I've tested it | Large ( > 3 GB) |
| Offline (not for first run though) |
Design of Integrated Circuits exercises (dicex) are the testbenches and model files you'll need https://github.com/wulffern/dicex
Custom IC Creator Electronic Design Automation (ciceda) is a docker image of a ubuntu linux with the necessary tools installed https://github.com/wulffern/ciceda
In a terminal or powershell
git clone https://github.com/wulffern/dicex
cd dicex
./ciceda_mac.shSee demo video
Expect that you will spend at least $$2\pi$$ times more time than planned (mostly due to software issues)

Find a problem that you really want to solve, and learn a programming language to solve it. There is absolutely no point in saying "I want to learn programming", then sitting down with a book to read about programming, and expect that you will learn programming that way. It will not happen. The only way to learn programming is to program, a lot. -- Carsten Wulff
#[fit] How
- ask a someone in your class
- use the "øvingstime and labratorieøvelse" to talk to teaching assistants. Don't ask about long future (future exercises).
If none of the above works, we'll use first few minutes in each lectures for questions on the previous content (but not future content).
- send email with questions on excercise, project, lectures etc. Long response time.
- use Teams. It interrupts the person your contacting.
- come to the office. I'm only at NTNU 20%.
There are approx 130 students. Email, teams, f2f does not scale.
