Download Sue2 V7 (Beta)
What it is: a fully modernized Sue2 schematic editor and its tools — CppSim, VppSim, and NGspice simulation, with new waveform viewers — now built on PySide6 (Python/Qt) and designed for AI interaction.
This Beta: MacOS (Apple Silicon) only; other operating systems coming.
Install: powered by uv, a modern Python tool manager — a seamless install on MacOS today, and on other platforms in the future.
License: free for academic and commercial use; no warranty or support is provided with this software.
Sue2 V7 Beta for MacOS (Apple Silicon Only) (76MB)
Installation (about 2 minutes):
1) Download and unzip Sue2_V7_Apple_Silicon.zip
2) Open Terminal, cd into the unzipped folder, and run: ./install.sh
Everything installs into your home directory
— no admin password, and your system Python is untouched.
Launching Sue2 V7:
Start: double-click the Sue2 application in your home folder's ~/Applications directory (note: inside your home folder, not the system /Applications), and drag it to your Dock if you like.
First launch: creates ~/CppSim with example design libraries (PLL synthesizers, delta-sigma converters, CDR, SPICE examples...).
Try it out: File ▸ Open, open sd_synth_fast, press CppSim, then Compile/Run, then AnaWave to plot signals.
Manuals: under Help ▸ Documentation.
Working with your favorite AI:
Open an AI tool that can access your files and run commands (Claude Code, Codex, etc.) and start with the phrase:
"Examine the ~/CppSim/AI folder and acknowledge when you are ready"
The AI will reply with a list of what it can help you with — creating schematics and symbols, running simulations, viewing waveforms, writing Python analysis scripts — and from there you just ask in plain language (e.g. "Open Sue2 and show me the sd_synth_fast schematic", "Run CppSim on it and plot the VCO input"). Every design edit an AI makes is automatically backed up, with one-command restore.
Uninstall:
Run the following commands in Terminal:
sue2 --remove-launcher
uv tool uninstall sue2
Your design data lives in ~/CppSim — remove that folder only if you also want your designs gone.
