Pasadena, Calif.--April 16, 1998--Tanner EDA introduced MCM Pro, a fully integrated tool for MCM design, layout, verification, and simulation.
The MCM Pro design suite automates many of the time consuming and error prone designentry tasks by interfacing with industry standard formats. A few of the key custom featuresare the automatic die symbol creation and footprint generation that automate the tasks thatdesigners do routinely.
S-Edit, the schematic entry for MCM and HDP designs, offers a powerfulautomatic symbol creation feature based on information contained in a DIEexchange format file to create die symbols with pin names. Both S-Editand L-Edit, our layout editor, easily interface with other tools via industrystandard formats (DIE, EDIF, GDS II, CIF, VHDL, DXF, and Spice,among others).
Time consuming place-and-route tasks can be automated within L-Edit/MPR. For example, a powerful die generation feature creates die layouts directly from DIE files. Manufacturing objects, such as anchor/thermal vias and pad via stack cells, are automatically inserted from the technology library. Expert routing is achieved by addressing MCM and HDP technology requirements for bare die, high-density, fine-line interconnects, and multilayer substrates.Further ease-of-use is provided by UPI support for manufacturing and testing and the flexibility to place die manually.
Using thermal data from the DIE file, L-Edit/Therm automatically meshes the layout andperforms a complete three-dimensional finite-element analysis. The analysis results areimmediately displayed showing the maximum temperatures of the die, substrate, andpackage, or two-dimensional temperature contours for top, bottom, slice, and cross-sectionviews.
Running an accurate design rule checker is greatly simplified for the designer because of user configurable rule sets. Multiple rule sets for routing, components, and minimum geometry size can be assigned to different regions of the design. L-Edit/DRC offers a time saving full-chip mode that can check an entire design or just a specific region. L-Edit/Extract has been modified to extract the important elements of HDP and MCM designs, such as die, pad/via stacks, discrete components, the I/O ring, and their connectivity. LVS compares the netlist files from the schematic and layout editor, pinpointing errors.
Embedded within the seamless signal integrity analysis process is the ability to extractinterconnect netlists using L-Edit/TLExtract. Transmission lines, coupled transmissionlines, and vias can be classified according to user specified criteria, such as length, width,and coupling distance, as well as associated with a user supplied model name. The modelsare described as parameterized Spice subcircuits making it easy for users to customizemodel internals. T-Spice performs time domain simulation of the HDP nets yieldinginformation on important performance characteristics, such as delay, skew,over/undershoot, droop, and crosstalk. T-Spice's graphical interface makes data entry easyand new state-of-the-art numerics provide excellent convergence characteristics. Themultiple window, multiple chart interface capability of W-Edit, a waveform andvisualization tool, permits signal integrity and electromagnetic analysis data viewing inhighly configurable formats.
SI-Calc empowers designers with all the capabilities of electromagneticanalysis without having to become an expert in boundary elementtechnology. Cross-section models in 2D of MCM multilayer interconnectscan quickly be constructed, automatically meshed, and analyzed usingadvanced boundary element methods to compute per unit length capacitance,inductance, conductance, and resistance matrices.
MCM Pro is immediately available for Windows 95 and Windows NT and Sun/Sparc systems. Pricing starts at $19,950. MCM Pro is being demonstrated at the MCM Conference, April 15-17, in Denver, booth number 426, and the Design Automation Conference, June 15-19, in San Francisco, booth number 1600.
