CIRCUIT SIMULATION TOOL

Seamless integration with the circuit diagram editor reduces the burden

on circuit designers by eliminating the need to rewrite their designs for analysis software.

Our analysis software supports AC/DC, transient analysis, operating point analysis, sensitivity analysis, and mixed digital-analog circuit analysis. We also offer Monte Carlo and parametric analysis. We support general model files, so it is possible to reuse model files used in other companies' SPICE. In addition, our software has a SPICE analysis engine that is equivalent to SPICE3f5, allowing for very fast circuit analysis. You can use WinSchematic-created circuit diagrams for various simulations on your desk.

#### VARIOUS SIMULATIONS

- Transient analysis
- This analysis allows you to analyze what waveform the circuit will output after a certain period of time if an arbitrary waveform is input to the circuit. It is used to analyze the output waveform of the circuit when the input waveform is a square wave (rectangular wave), sine wave, or triangular wave, and to examine the response when a pulse is input. In addition, it supports DC power supply and arbitrary waveform inputs, and can handle both linear and nonlinear components.

- AC small signal analysis
- This method analyzes what waveform the circuit will produce when a sinusoidal input signal is applied. This type of analysis is equivalent to measuring a circuit board using a spectrum analyzer.

- DC Sweep Analysis
- DC sweep analysis involves analyzing the voltage/current at each node when the voltage of a DC voltage source is varied. While this function shares the feature of measuring voltage with operating point analysis, DC analysis can analyze and display the waveform of direct current behavior that accompanies changes in the DC power supply, unlike operating point analysis which only analyzes the circuit once.

- Monte Carlo Analysis
- For each analysis, random values are assigned to the specified component ratings and the analysis is repeated a specified number of times. This allows us to measure the variability of the waveforms at measurement points.

- Parametric analysis
- This is an analysis in which for each analysis, arbitrary values are input for a specified component's rating and the analysis is repeated a specified number of times. As a result, appropriate filter values can be measured.

- Operating point
- In operating point analysis, the voltage value of any node in a circuit is measured when a current is flowing through the circuit. This function is equivalent to connecting a DC power supply to an actual board and measuring the voltage value of any node on the board using a tester. Operating point analysis performs calculations on a circuit after allowing enough time for current to flow through it. Therefore, capacitors on the circuit are treated as open and coils are treated as short-circuited. This is similar to measuring on an actual board with a power supply connected and using an oscilloscope to measure.

- Sensitivity analysis
- Sensitivity analysis is an analysis that calculates the impact on a measurement point when the voltage changes by 1V in the vicinity of the operating point.
