WeSpice

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

WeSpice is a robust and flexible digital circuit design suite for everybody - professionals and hobbyists alike.

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

No want to remain linked on a daily basis to some server - everything is included!

== Features ==

From transistor-level to advanced modeling, every little thing is straightforward to construct and simulate.

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

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

All tools work collectively seamlessly, so you can go fast from design concept to outcomes. No need to look under the hood.

When you want more management, you might have that also: all recordsdata are editable text that you can tweak.

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

Share actually anything (including schematics, symbols, models, netlists, results, display screen snapshots), via mail or some other app.

Pre-made symbols for all primitive parts.

Several pattern schematic, including: folded cascode OTA, bandgap reference, chargepump, sigma-delta ADC models.

Easy-to-use results browser permits to plot and measure. Pick your outputs directly from the schematics or from an inventory.

Try our free WeSpice Demo!

The demo version has much less functionality, however nonetheless allows you to try out many of the options.

We recommend installing 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 mostly on Berkeley SPICE 3F5. Compared to SPICE 3F5, NGSPICE has many additions, is extra steady and runs faster.

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

The CIDER extension adds gadget simulation (TCAD), by offering accurate one- and two-dimensional numerical system 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 enjoying with this app or another.

Some advanced system models are multi-threaded to reap the advantages of at present's multi-core processors. Schematics with many BSIM3 or BSIM4 transistors run on 4 cores in lower 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 a lot as 4.7.0), BSIMSOI (3.3 and 4.4), SOI3, HiSIM.

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

== Compatibility ==

Tablets and telephones from approx. 3.7 upwards.

ICS (Android 4.0.3) or later.

SD-card or emulated equal storage.
