Video Tutorial on Simulation of Single-Event Upset in SRAM Cell
In the first tutorial, you will learn how to estimate the SEU rate of a memory chip in a satellite, in the following steps:
- Constructing a 3D device model of an SRAM cell from mask layout;
- Simulating the initial state of the SRAM cell before irradiation;
- Simulating the trajectories of incident energetic particles in the device in VisualParticle;
- Simulating the transient response of the SRAM cell when hit by an energetic particle;
- Plotting the voltage and current waveforms of the SRAM circuit nodes, to determine if a data upset has occurred to the cell.
- Visualization of the evolution of internal variables (potential and carrier concentration) in the SRAM cell that led to the upset.

CMOS Logic Gates
Want to simulate small logic circuit cells in 3D? Genius allows you to simulate a complete cell in a single TCAD model.
Or if you want to simulate it the traditional way, you can still perform a mixed-mode circuit and device simulation using SPICE.
