San Francisco, California - July 23, 1998 - CAD-Migos Software Tools today announced two new feature enhancements to their flagship product, SPICE-IT! for Windows. These enhancements, in combination with introductory pricing of under $1000, continue to make this package one of the best EDA values on the market today.

The foundry supported primitive model, BSIM3V3.2, using the recently developed code from the University of California, Berkeley, is now supported for both netlist-based and schematic-driven simulations. Many semiconductor foundries and manufacturers are now supporting the BSIM3 models as evidenced by the BSIM3 web site at Berkeley (http://www-device.eecs.berkeley.edu/~bsim3/intro.html). The BSIM3V3 model was originally established by Sematech as the first industry-wide standard of its kind in 1996.

The model feature improvements as defined by UC Berkeley include:

In addition, SPICE-IT! now supports syntax sensitive text editing for spice netlists making the task of editing custom, imported netlists simpler and easier. The system automatically displays numerical values, keywords, comments, and other sensitive data values in different highlighted colors making the task of editing netlists simpler and less error-prone. These editing features are quite popular with IC designers unable to use the familiar board-level method of schematic design entry for simulation.

Product description: SPICE-IT!* for Windows Version 1.70 is a powerful, integrated electronic integrated circuit design and mixed-mode simulation system. SPICE-IT! consists of a Berkeley SPICE 3F5-compatible, interactive mixed-mode SPICE simulation engine, a graphical schematic editor, a component library symbol editor, a SPICE Model Wizard and integrated Internet support.

The core of SPICE-IT! is a true mixed-mode simulation engine. Digital, analog, non-electronic systems, event-drive simulation extensions, user-defined data types and algorithms can be combined in a single simulation! SPICE-IT! provides simulation capabilities above and beyond the traditional simulation tools monte carlo, worst case, sensitivity, noise and distortion analysis, and enhanced mathematical convergence methods. The simulation system accepts both ASCII netlists and schematics.

SPICE-IT! and the associated Code Model subsystem allow use of all the standard SPICE models, provide a pre-defined collection of the most common analog and digital functions, and provide an extensible base on which to build additional models. Users can easily add new models directly into the simulator. Hybrid circuit models such as A/D and D/A converters are also provided and supported in this product.

SPICE-IT! supports creation of "User-Defined Node" data types. These allow the operator to specify nodes that propagate data other than voltage, currents, and digital states. Like digital nodes, User-Defined Nodes use event-driven simulation, but the state value may be an arbitrary data type. A simple example application of User-Defined Nodes is the simulation of a digital signal processing filter algorithm

The WYSIWYG Symbol Editor features the ability to create, maintain, and manipulate graphical symbols. The WYSIWYG Schematic Editor provides the ability to logically connect the library symbols in multi-layered schematics, as well as the ability to establish unlimited test points and stimulus points for subsequent simulation. A simple-to-use Electrical Rules Check (ERC) provides schematic checking over 13 pin types. Automatic graph generation from test points and layered axis support are indispensable in visual correlation of output. The Project Organizer Toolbar allows the user to organize schematics, graphs, plots and components. The SPICE Model Wizard provides the ability to quickly build SPICE models from data sheets, and uses immediate visual feedback from an active graph during model generation to help ensure accuracy. The Model Wizard includes support for a variety of SPICE device types and subcircuits including op-amps, diodes, and comparators. Internet support is provided for searching, retrieving and publishing documents. Additional features include circuit debugging, extensive device-model libraries and templates, OLE support for Drag and Drop, and 26 export formats.
