The program was originally written at Berkeley and been enhanced by several organizations since it's original release. Magic implements layout database structures using scalable design rules and offers unique layer handling operations to support scalable rules. Over the last three years, the Advanced Microelectronics (AuE) division of ITD has contracted with DARPA and other government agencies to provide support, updates, and enhancements to the original Magic layout tool. Our latest Magic release is based on the Magic 6.3 release made by DEC in September of 1990. Magic runs on a number of platforms, including Sun SPARC, Sun3, MacII, DECstations and several other BSD and system V derivative platforms. X11 and Sunview window graphics drivers are also provided. The AuE Magic release provides hierarchical SPICE and LSIM netlist extractors not available in previous Magic releases. Previously, a flat SPICE netlist could be obtained using a program called "ext2spice". AuE provides a hierarchical SPICE netlister which provides a robust set of SPICE parameters for every device, including transistor source/drain diffusion perimeters and areas. The extractor has also been modified to correctly account for the shared S/D regions on stacked devices. The AuE extractor supports LSIM netlists, an Hspice compatible netlist, and a SpiceIIG compatible netlist. The SpiceIIG format uses node numbers instead of node names. The AuE SPICE extractor also recognizes bipolar junction transistors (BJTs) in several configurations. The previous Magic netlist extractor does not recognize BJT devices in any form. A new capacitance rule has been added to the base Magic extractor to facilitate the extraction of accurate dielectric capacitances. The previous verion of Magic did not handle coupling capacitances correctly and frequently inserted a substrate capacitor in addition to the correctly extracted coupling capacitor. The AuE Magic release also includes an updated and enhanced technology file. Modifications include fixes to several MOSIS DRC rules which were previously improperly checked, modifications to the CIF writer to resolve software bugs, and updated capacitance and resistance values in the extraction sections of the tech file. Special extraction sections for more commonly used processes have also been added. Modifications since the last Magic release - - Moved from Magic4 to the DEC release Magic 6.3 - The extractor now extracts junction capacitance geometry parameters. Explicit diodes for transistors are no longer used. - Fixed the Calma stream reader so that it can handle negative angles and angles > 360 degrees. - Added a BJT extractor to the SPICE netlist extractor. - Modified the SPICE extractor so that when multiple transistors share diffusions, the entire diffusion capacitance is lumped to one of the transistors. The diffusion capacitance on the other transistors is zeroed out. The previous versions of the extractor would incorrectly sum the capacitance at shared nodes. - Modified the extractor capacitance overlap rule to improve the extraction results for layer to layer coupling capacitances. - Resolved a problem with interactions between Magic's internal memory manager and the Sun C library string manipulation functions. This problem caused fatal crashes in Magic. For information on how to order this version of Magic send an E-mail request to magic@AuE.com or send your request in writing to the address given below. We will start filling orders in mid October. _______ / | ====/ |============================================================== | / | Dan Johnson Advanced Microelectronics | | / | CAD Operations Manager 1080 River Oaks Drive | | \ | Fax: (601)932-7621 Suite A-250 | | |Jackson | Phone: (601)932-7620 Jackson, MS | | / * | danj@AuE.com 39208 | ===/ |============================================================== |______ | / | \____|
