WeSpice

Analog, digital and mixed-signal circuit design and simulation on your device!

WeSpice is a powerful and flexible electronic circuit design suite for everyone - professionals and hobbyists alike.

The simulation engine is NGSPICE, operating regionally on your system.

No want to remain related on a regular basis to some server - every little thing is included!

== Features ==

From transistor-level to superior modeling, every little thing is straightforward to build and simulate.

Device TCAD, 1D and 2D modelling and simulation.

Flexibility to construct hierarchical schematics, symbols, and fashions (including corners).

All tools work collectively seamlessly, so you presumably can go quick from design concept to results. No have to look beneath the hood.

When you want more control, you have that additionally: all files are editable text that you could tweak.

At all steps you presumably can import information and proceed (including models and spice input: netlists, commands, and so forth.).

Share literally anything (including schematics, symbols, fashions, netlists, outcomes, screen snapshots), via mail or another app.

Pre-made symbols for all primitive components.

Several sample schematic, together with: folded cascode OTA, bandgap reference, chargepump, sigma-delta ADC fashions.

Easy-to-use outcomes browser permits to plot and measure. Pick your outputs directly from the schematics or from a list.

The demo version has less functionality, however nonetheless allows you to check out many of the features.

We recommend putting in the demo first, to verify compatibility and ease of use (especially for small phones).

Limitations: no Symbol Editor and Model Manager, massive schematics are not saved, long simulations are truncated.

== Simulator ==

The simulator is NGSPICE, based on Berkeley SPICE 3F5. Compared to SPICE 3F5, NGSPICE has many additions, is more secure and runs sooner.

The XSPICE extension provides event-driven simulation capabilities, allowing environment friendly simulation of digital and mixed-signal schematics. It consists of new code models for analog, digital and real capabilities, along with digital and actual node sorts.

The CIDER extension adds system simulation (TCAD), by providing correct one- and two-dimensional numerical gadget fashions primarily based on the answer of Poisson's equation, and the electron and gap current-continuity equations.

The simulator itself runs in background when you proceed playing with this app or another.

Some advanced system models are multi-threaded to take advantage of at present's multi-core processors. Schematics with many BSIM3 or BSIM4 transistors run on four cores in less than half the time needed on one core.

Analyses: OP, DC, AC, TRAN, DISTO, NOISE, PZ, SENS, TF.

MOS models: MOS1-3, MOS6, MOS9, BSIM1, BSIM2, BSIM3 (all up to 3.3.0) BSIM4 (all as much as 4.7.0), BSIMSOI (3.3 and 4.4), SOI3, HiSIM.

Safe operating space (SOA) checks can be found for resistors, capacitors, diodes, BJTs and BSIM MOS.

== Compatibility ==

Tablets and phones from approx. 3.7 upwards.

ICS (Android 4.0.3) or later.

SD-card or emulated equal storage.
