JKU IIC OSIC-Multitool for open-source IC (OSIC) design for SKY130.

A Linux-Local Installation of TT tools at version parity with TinyTapeout Selected Versions (see branch name)

An interface to use ngSpice C shared libraries from FORTRAN. Bindings to the shared library functions and a class to define a circuit, with functions to operate on it (reading netlist, changing node properties, reading node voltages, etc)

A web-based system for designing and simulating electronic (eSim) and Arduino circuits.

A project exploring the characteristics of MOSFETs using circuit simulation in NGSPICE. The code simulates various transistor behaviors and models, providing insight into MOSFET switching and amplification properties.

A project for designing and implementing TTL to CMOS and CMOS to TTL interfacing in a microcontroller environment using NGSPICE. The code includes simulations and analysis of signal behaviour across different logic families.
