Technical tutorials, teaching guidance, release notes, and analyses of the simulator’s implementation boundaries.
The most important choice in analog simulation is often not the component—it is the analysis mode. The same circuit can answer very different questions depending on whether you calculate...
An electric-circuit simulator becomes useful when it helps you make and test a prediction—not merely draw a neat schematic. A strong first workflow is therefore measurement-first: choose...
TL;DR: This is a working 4-bit teaching CPU inspired by the Intel 4004, not an emulator or transistor-level reconstruction. It uses a custom instruction set, unified memory...
In the previous post, we built a D latch: a level-sensitive circuit with a Data input and a Write-enable line. While Write is asserted, the latch is transparent...
The previous post ended with something genuinely new in this series: a circuit that could remember. The R-S latch, built from two cross-coupled gates, held its output even...
The previous post examined an inverting feedback loop. In a physical implementation with sufficient loop gain and propagation delay, an odd-inversion loop can oscillate; in a digital simulator, that...
TL;DR: Place a relay’s normally closed contact in series with its own coil and the relay can repeatedly energize and release. The Boolean loop has no stable 0-or...
