Claiming to reduce risk and time to market, Microchip has updated its MPLAB Mindi analogue simulator to include over 300 device models and schematics.

MPLAB Mindi supports digitally enhanced power analogue (DEPA) controllers, linear regulators, MOSFET drivers and LED drivers. According to Microchip, it enables more accurate and faster simulation including transient and stability analyses. A free download makes MPLAB Mindi analogue simulator accessible to all customers, regardless of size.

The MPLAB Mindi analogue simulator circuit simulation tool supports more than 300 Microchip analogue products, with SIMetrix’s enhanced simulation program with integrated circuit emphasis (Spice) and Simplis Technologies’ Simplis (Simulation of Piecewise LInear Systems) simulation environments.

Analogue simulation is often a crucial step for circuit design, where complicated device interactions can be difficult to refine and debug in hardware, explains Microchip. Using the proper simulation tools can help designers avoid significant risk, decreasing time to market and saving costly hardware revisions, it counsels. The MPLAB Mindi analogue simulator can test a circuit or sub-circuit, including transient and stability analyses, to provide an estimation for the target circuit operation.

Many applications require simulation before production. Companies were often reliant on third-party providers or internal development for their analogue component models, while many smaller companies which want to run simulations are not able to afford tool licences for a full software package.

The MPLAB Mindi analogue simulator allows for fast simulation of a variety of circuits, including closed-loop control systems such as filters, power supplies and motor-drive applications.

The updated simulator is powered by SIMetrix/Simplis 8.1 software package, with added support for file-defined piecewise linear sources, Laplace transform transfer functions, arbitrary filters, Fourier analysis plots, transmission line modelling and improved convergence in the SIMetrix environment. The update also adds convergence reporting to help with debug issues in the SIMetrix environment.
