CircuitSim 1.3.0

The 1.3.0 release adds discrete (single-package) transistors, BJT support, configurable diode models, and a big upgrade to the graph screen with measurement cursors. It also ships a playable example world so you can see working circuits without wiring anything yourself.

New Components

Discrete Transistors

• Discrete NMOS / PMOS — single-block MOSFETs as an alternative to the multi-block IC MOSFETs, each with its own edit screen.
• Discrete NPN / PNP BJTs — bipolar junction transistors.

All four come with their own block, item, creative-tab entry, loot table, block model, edit screen, and network sync packet.

Component Improvements

• Diode models — the diode edit screen now has an optional .MODEL field. Leave it blank for the built-in basic SPICE diode, or enter a model name (e.g. D1N4148_1) to use a model from your library (PSpice).
• Voltage probe "name only" mode — a new checkbox lets a voltage probe name and merge its net without plotting/printing it, useful for naming nodes you don't want cluttering the output.

Graph Screen

• Measurement cursors — toggle a pair of OrCAD-style vertical cursors per plot. Drag cursor 1 with the left mouse button and cursor 2 with the right; the readout shows X/Y at each cursor plus the dx/dy between them.
• Independent cursor and log-axis toggles for the top and bottom plots.

Simulation

• "None" compatibility mode — you can now pick none when choosing the simulator compatibility mode.
• Various netlist-builder and circuit-extractor updates to support the new components and diode models.

Example World

• The repo now ships a ready-to-play save in example_world/ ("Zaza The Creator") with a set of pre-built example circuits — from simple passives up to controlled sources, the Amplifier block, and IC/PDK components. Copy the folder into your saves/ directory to load it.
  • Note: some examples reference .lib files by absolute path; update those paths to match your own PDK install/OrCAD libraries before simulating them.

Other Changes

• New Simulate Block edit screen layout.
• Mod icon changed to the amplifier texture.
• README updated with animated GIF previews (non-inverting amp, Miller amp, MOSFET output characteristics) and an Example World section.
