Multiple Schematic Layers: SpiceNet lets you put schematic objects (test circuitry, artwork, etc.) on different layers. You can configure the combination of layers you want to simulate, print, or send to PCB layout. Shown in highlight below are two layers used in the Closed loop configuration of sample.DWG. The first layer contains the "core" circuitry and can be used for the production configuration of the circuit. The production configuration does not have test parts and circuitry so that layout, procurement and manufacturing can proceed without confusion that would otherwise result from having to connect or buy parts that were present just for the simulation.

Multiple Design Configurations: Here we see a production drawing and two test configurations (Open Loop and Closed Loop, bottom). All are part of the SAME schematic database. With SpiceNet, you don't need to recapture a different schematic for each design function. Changing a parameter on one configuration automatically carries through to each configuration that uses the same part.

 

• Auto-label placement makes it easy to capture a good-looking schematic rapidly.
• Automatic on-the-fly connectivity saves you time - there's no need to place connectivity dots.
• Intelligent part attribute editor simplifies data entry and allows you to edit any part graphically or via a list.
• There is no need to separately generate a SPICE netlist; a simple menu function does everything for you and launches the simulation right from SpiceNet.
• Hierarchical Bus support gives you added flexibility for mixed signal designs.

• On-line symbol editor and Symbol Wizard make it easy to add or reconfigure symbols.
• Quick symbol modify and replace function gives you the schematic appearance you want.
• Symbol shapes including arcs, ellipses, Beziers, polylines, fills, metafiles, and colored bitmaps enable you to make production schematics that stand out.

• Enter data for all SPICE analyses using "fill-in-the-blank" dialogs; there's no need to know SPICE syntax.
• Change any model parameter in the design or add a new model based on an existing device.Several powerful model-building tools are also available.
• Monte Carlo tolerance dialog lets your schematic database hold custom tolerances for all parts.
• Support for gamut of vendor supplied SPICE models.
• Simulation fully controlled from any task (schematic, text editor or waveform viewer with full real time waveforms as simulation progresses).

• Following a simulation, the user can execute a linear, logarithmic, or list sweep of passives component values (resistors, capacitors, inductors), semiconductor temperature (i.e., diode, BJT, MOSFET, etc.) or overall circuit temperature. A curve family is generated.
• Significant gain in speed is achieved because each simulation run is based on data preserved from previous runs (e.g., nodal equation matrix preserved), thus eliminating at least 95% of the overhead in simulation time.

• Following a simulation, the user can click on any node or part on the design and instantly plot the corresponding voltage, current, or power thumbnail waveform directly on the schematic, or view in IntuScope for further analysis
• Resizeable waveforms can be placed directly on the schematic; no separate display dialogs or programs are needed
• Test point symbols let you see current or power from any device or any node voltage.
• Detailed or brief operating point information can be displayed on the schematic
• Cross-probe node voltages, device currents and power dissipation
• Cross-probe data from the AC, DC, or Transient analyses
• Print or copy schematics with waveforms and operating point data to the clipboard; great for documentation purposes

Two new powerful Wizards are included in SpiceNet. Together, they eliminate the SPICE syntax complexities; built from years of experience in technical support, these wizards answer 90% of commonly asked questions. The Convergence Wizard makes it easy to solve your toughest convergence problems without having to know SPICE syntax. Based on your answers to simple questions, the Convergence Wizard intelligently optimizes key .OPTIONS variables for you. The Analysis Wizard helps novice and power users specify all key SPICE analyses without the use of a SPICE reference guide.
