Circuit Design - Simulation


Circuitmod is a circuit simulator that extend the capacity of the original Falstad's Java Circuit Simulator into CMOS Chips, Led Arrays, Led Matrix and PIC Programming. The Horizon is limitless.

ADIsimPE Linear and Mixed-Signal Circuit Simulator

ADIsimPE, which is powered by SIMetrix/SIMPLIS, is a circuit simulation suite optimized for the design and development of analog and mixed signal circuits. SIMetrix mode is ideal for the simulation of general non-switching circuits. It provides full Pspice compatibility for use with industry-standard SPICE models. SIMPLIS (SIMulation Piecewise-Linear System) mode simulates the operation of switching circuits with vastly improved robustness, speed, and accuracy compared to standard SPICE. It is particularly useful for switching power supply, PLLs, and ADC/DAC applications. Download need registration.

Software environment for modeling and analysis of high-frequency electrical circuits. RFSim99 is an editor for designing unique high-frequency radio components, as well as developing circuit diagrams of electronic devices by inserting ready-made elements from the proposed libraries. It is possible to calculate the design parameters and basic characteristics of simple and printed coils, capacitors, five different types of directional couplers, two samples of microstrip, two-wire and coaxial transmission lines, as well as splitters (resistive and Wilkinson).

A unique simulator designed for high-speed analysis of linear and mixed circuits. The SIMPLIS application (an abbreviation of "SIMulation for Piecewise LInear System") was created with the goal of quickly modeling power supplies and switching regulators, as well as researching key circuits of voltage converters. It, like the SPICE program, functions at the component level of the radio circuit; however, it performs analyzes of transients 10-50 times faster. SIMPLIS achieves a similar simulation speed due to the use of piecewise linear approximation instead of solving systems of nonlinear equations used in the SPICE program.
