Design and adjust the structures and functionality of electrical devices by configuring various circuits in a simulated environment for analog/digital schemes with interactive sketching options, periodic steady-state analysis, and 3D plotting tools, etc.
Micro-Cap is a utility aimed at electronics engineers. It was especially created to help them design electronic circuits and simulate their functioning.
The program integrates a large device library. Some of the devices included in the "analog primitives" section are passive components, active devices, waveform sources, functions, Laplace and Z transforms and dependent sources, macros, modulators. Actually, there are 258 items of the "analog primitives" section, no less than 21928 items of the analog library, 88 digital primitives and 2050 items of the digital library. Some animated components are also available. Several types of analysis can be performed, such as AC, DC, dynamic DC and dynamic AC or harmonic distortion. One can perform schematic waveform probing, Monte Carlo analysis, and different kinds of plots and measurements. In order to visualize the effects of parameter variations, 3D plotting is also possible. Behavior of different components can be investigated and modeled. Once a circuit is sketched, it can be analyzed and also edited while being in the analysis mode.
The utility is a professional tool for electrical engineers, as it offers a large array of options so that they can easily perform the simulations required for their projects.
v11.0.3.4 [Dec 9, 2013]
- 64 bit version
Micro-Cap 11 comes in two varieties, a 32 bit version which can access 3G of RAM and a 64 bit version which can access as much as 192G of RAM. The 192G version can analyze circuits with 10 million components.
- Analysis Worst Case
This analysis mode, finds worst case performance limits for a circuit using RSS, Monte Carlo, and Extreme Value methods.
- Stability Analysis
This type of analysis is used to find the stability limits for linear circuits using either the Tian or Middlebrooke methods.
- Schematic Editor Encryption
Password-protected encryption can now be used on circuit, macro and library files.
- Title Block Editor
A Title Block editor was added that allows multiple fonts, adjustable size, and title block template save and recall for greater ease of use.
- Rich Text Format
An option for RTF text format was added, enabling super and sub-scripting, and font, style, size and color control of individual words within a text block.
- Text Angle
An option was added to allow arbitrary text angles.
- Command Statement Builder
A command statement builder was added to help construct .measure, .warning, .help, and .define statements.
- Schematic Background
Background images, including watermarks, can be added to a schematic.
- Graph Paper Option
Graph Paper was added to the Grid options
- Auto Scale (F6)
An auto scale option was added to the schematic.
- Unconnected Pin Markers
Pins and wires that have no connections can be marked with a special symbol (yellow triangle) that shows possible faulty wiring.
- Bill of Materials Excel File Output
An Excel file can be created from the BOM contents.
- BOM Optional Expand
The define values can optionally be expanded in the BOM, so that .DEFINE RX 3K shows up as 3K and not RX.
- Attribute Dialog Box Disable
The automatic display of the Attribute Dialog box that occurs when you place a component can be eliminated. This is convenient when drawing a general schematic without values.
- Expandable Attribute Dialog Box
This dialog box can now be expanded by dragging the Size grow icon, making viewing large subcircuits easier.
- Dialog Box Location Save
The location of major dialog boxes can be saved, even if they are on different monitors.
- Text Grid Snap
A feature was added to disable or enable grid snap for text.
- Find / Replace Improved
This command was improved to include whole word search and to show the schematic location of the found item behind the dialog box.
- Enable Region Box
An on/off check box was added to the enable region to make it easy to disable/enable the region expression checking.
- Find in Files Command
An All option was added to this command.
- Push-pin Text
Push-pin text can be enabled in the Text dialog box. Placing a mouse over the text displays the text. Otherwise just push pin is shown.
- Embedded Images
Image files in a circuit can now be localized (embedded or saved in the circuit file) making the circuit file more portable.
- Drag and Drop Pictures
Images can be dragged from one application and dropped into a Micro-Cap schematic or analysis plot.
- Info Page Options
Info page content can be chosen from the circuit Properties dialog box (F10).
- Properties Dialog Box Object Colors
The color of each schematic object is displayed beside the item for greater clarity.
- Change Dialog Box
The Change dialog box now shows selected components.
- Measurement and Plotting Performance Functions
An integration operator that integrates a waveform between two X values and a Peak-to-peak operator that measures the peak to peak of a waveform over the simulation run were added.
- Measure Command
The HSPICE .Measure command was added.
- Measurements Window
A measurements window shows the results of .measure and performance functions.
- Measure Library
Common measurement functions using the basic .measure command set. Includes pulse width, frequency, period, overshoot, delay, and power factor.
- FFT Windowing Functions
Extensive set of FFT windowing functions (Rectangular, Cosine, Tukey, Barlett-Hann, Blackman, and many more)
- FFT Window Reference Frequency
For HARMN, db(HARMN), THD and IHD
- Fourier Integral
An option for computing Fourier spectra using the Fourier integral rather than the FFT was added.
- Fourier Plots
An option for cliping baseline db values and ignoring the phase computation for low db values was added.
- Curve Fitting Utility
This is a linear and polynomial curve fitting utility for analysis plots.
- Ignore Illegal Plots
This is an option to ignore analysis plots that have a disabled or missing part or node, for cases where you want to switch between enabling and disabling circuitry and have the analysis limts plots still be legal.
- More Plot Groups
Up to 19 plots within each plot page can be named and used.
- Adjustable Plot Height
Analysis plots heights can be adjusted by dragging.
- Dynamic AC
Temperature and frequency were added to the text display.
