3Spice (often stylized as 3-SPICE) refers to McCAD 3-SPICE, a proprietary interactive mixed-mode circuit simulation software engineered by McCAD Electronic Design Automation (EDA) Software. It is structurally built upon Spice3 (specifically version 3F5), which is the industry-standard C-language-based analog circuit simulator originally developed by UC Berkeley.
The primary objective of 3-SPICE is to mathematically predict, test, and analyze the behavioral properties of analog, digital, and mixed-signal electrical designs before physical PCB fabrication. Key Capabilities and Analyses
The 3-SPICE simulator can resolve a diverse selection of circuit conditions using several essential forms of mathematical analysis:
DC Analysis: Calculates steady-state voltage and current node distributions with inductors shorted and capacitors opened.
AC Small-Signal Analysis: Computes small-signal output variables across a spectrum of frequencies.
Transient Analysis: Determines time-domain responses over specific intervals.
Advanced Extractions: Evaluates Pole-Zero, Transfer Functions, Distortion, Noise, Sensitivity, and Fourier frequency spectrums. Software Features & Components
Integration: It operates as a stand-alone simulation engine or fully integrated with McCAD Schematics Plus. Combining them into the “SimPlus bundle” allows seamless schematic capture, netlist generation, and interactive plotting.
Performance: Optimized specifically to harness modern processor computing speeds, ensuring fast matrix integration computations compared to traditional legacy batch-processing engines.
Supported Models: 3-SPICE provides flexible modeling for semiconductor and passive elements, including MOSFETs, GaAs MESFETs, diodes, resistors, capacitors, inductors, voltage/current switches, and lossy/coupled transmission lines.
Are you planning to run a specific type of analysis (like AC or transient) inside McCAD 3-SPICE, or do you need help comparing it to other modern options like LTspice or QSPICE? Info – 3SPICE Simulation – McCAD
