Microchip’s SPICE/SIMPLIS free analogue simulator extends device coverage
Microchip Technology’s MPLAB Mindi analogue simulation software, has been updated to include more models and features; the circuit simulation tool now supports more than 300 Microchip analogue products.

Mindi supports SIMetrix’s enhanced SPICE (Simulation Program with Integrated Circuit Emphasis) and SIMPLIS Technologies’ SIMPLIS (SIMulation of Piecewise LInear Systems) simulation environments. The updated Mindi analog simulation software is available as a free download fro the link below.


Where complicated device interactions can be difficult to refine and debug in hardware, analogue simulation with appropriate simulation tools can help designers avoid significant risk, decreasing time to market and saving costly hardware revisions, Microchip observes. The MPLAB Mindi Analog Simulator can test a circuit or sub-circuit, including transient and stability analyses, providing estimation for the target circuit operation. Microchip contends that many smaller companies wanted to run simulations but were not able to afford tool licenses for a full software package, and says that the features and affordability of the MPLAB Mindi Analog Simulator make it an option for customers of all sizes.


The MPLAB Mindi Analog Simulator allows for fast simulation of a wide variety of circuits, including closed-loop control systems such as filters, power supplies and motor drive applications. Powered by SIMetrix/SIMPLIS simulation engines, and pre-loaded with Microchip’s analogue device models, this analog simulation package allows for more accurate and faster simulation.


The updated software package now includes support for additional Digitally Enhanced Power Analog (DEPA) controllers, linear regulators, MOSFET drivers and LED drivers not present in previous software releases. In addition, it is based on the 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 modeling and improved convergence in the SIMetrix environment. The update also added convergence reporting to help with debug issues in the SIMetrix environment.


“Customers want a full solution, including software tools,” said Keith Pazul, director of marketing for Microchip’s Analog, Power and Interface Division. “The MPLAB Mindi Analog Simulator complements the compiler and integrated development environment Microchip is famous for, adding analogue simulation capabilities.”
