Interactive engineering labs for FPGA and ASIC concepts, digital interfaces, signal integrity, measurement, DSP, RF, quantum mechanics, electromagnetics and optical communications. Change the parameters and observe the behavior directly in your browser.
Explore by engineering domain. Each lab combines an interactive model with technical explanations so you can change parameters, observe the result and connect the behavior back to the underlying engineering.
Digital hardware
Explore timing closure, static timing analysis, clock-domain crossing and cycle-accurate bus transactions used in FPGA and ASIC systems.
Explore setup and hold timing, slack, clock skew, timing constraints, metastability and clock-domain crossing.
FPGA AXI, APB & Digital Bus Timing LabInspect APB, AHB, AXI, Avalon, Wishbone, I²C and SPI transactions cycle by cycle, including handshakes and timing.
BUSHardware behavior
Study how real interconnects and instruments alter fast signals through reflections, impedance discontinuities, bandwidth limits, sampling and aliasing.
Explore transmission lines, reflections, termination, differential-pair skew, crosstalk, controlled impedance, vias and return paths.
SI Oscilloscope Sampling & Aliasing LabExplore analog bandwidth, anti-alias filtering, sample rate, Nyquist limits, aliasing and waveform reconstruction.
SCOPESignals & radio
Move between time, frequency and impedance domains using interactive DSP filters, RF signal chains and Smith-chart matching concepts.
Compare FIR and IIR filters, DFT and FFT behavior, impulse response, frequency response, sampling and practical filtering effects.
DSP RF Filters & Signal Chain LabBuild an RF signal chain and explore cascaded filtering, gain, attenuation, noise and end-to-end frequency response.
RF Smith Chart & RF Impedance LabVisualize impedance, reflection coefficient, transmission-line transforms and impedance matching directly on the Smith chart.
RFPhysical systems
Explore wave mechanics, electromagnetic fields, geometric optics and atmospheric effects that connect fundamental physics to communication hardware.
Explore Schrödinger evolution, Fourier pairs, energy levels, Pauli exclusion, wavefunction collapse, double-slit interference and entanglement.
QM Electromagnetic Fields LabVisualize moving charges, electric and magnetic fields, propagation and retarded electromagnetic effects.
EM Geometric Optics & Ray Tracing LabExperiment with reflective surfaces, optical geometry and ray tracing to see how light propagates through an optical system.
OPT FSO Atmospheric Turbulence LabExplore atmospheric scintillation, turbulence strength and received optical-power variation across a free-space optical link.
