Responsibilities:- Was code designer and sole implementor of ETAK’s “Zero-Track” database format for CD-ROM and workstation applications, including Geocoding, Navigation, and Fleet Management Systems applications. This highly compressed (roughly 20 to 1 over the source data) database format is designed for speed of access in real-time applications in CPU and memory constrained environments.- Created a high resolution workstation and interactive editor for cartographic applications. Hardware was based on an IBM-AT clone (under both MS-DOS and several versions of UNIX) with a high resolution graphics card and terminal, using a VAX (under VMS) as a high speed file server. Software included VAX communication, user interface, algorithms, graphics, and database design. Language used was C. - Wrote the low level graphics driver software and the upper application levels for the graphics applications. The device driver was written in C under MS-DOS using a shared (dual ported) memory model. - Worked on data integrity programs for the cartographic database (both topological integrity and internal database integrity). Worked on various transformation and compression programs for the cartographic database, taking it from the format used for data entry to the format used in the digital cassette tapes and CD-ROM in the ETAK Navigator and Map WorkStation. Extended the capabilities of these systems. - Enhanced HP plotting software to deal with new features in the database. - Participated in the design and implementation of the second generation digital cartographic system (MapEngine), including an interactive graphics editor. - Provided customer support related to OEM programming using the MapEngine. - Ported a large set of VAX/VMS programs to run under XENIX on a 386-based PC and under UNIX on a Sun 386i workstation. This work involved emulating and/or replacing VAX RMS indexed files and writing code that would conditionally compile and run efficiently and correctly on all three platforms. |

Responsibilities:- Algorithm design, implementation, and documentation for the Gatemaster project. This involved providing software (and graphical) tools for the LSI and VLSI design engineer to go from the schematic to actual component layout and interpin routing on gate arrays.- Designed a text syntax for presenting gate array connectivity and layout information from the Gatemaster data base to chip manufacturers, helped negotiate its acceptance by a major semiconductor company, and implemented the program (MAKE) which interrogates the data base and produces the file. Also worked on intercomputer communications protocols for the data transfer process and debugging the entire system from front to back. - Created and implemented a tool which increased the success rate of the automatic routers for gate array net interconnections. This tool not only significantly increased the number and fraction of nets routable to completion but also immediately indicated unroutable chips before any time is spent trying to route them, thus saving the design engineer many hours of wasted labor. - Worked on an automatic/interactive placement tool for gate array layout based on a force relaxation model for constructive initial placement. Adapted it from some models in the literature, designed its interface with the user and with the Gatemaster data base, its internal data structures, and the details of its implementation. - Project leader, designer, and implementor of a placement improvement system for gate arrays based on component interchange algorithms with user-selectable metrics and component selection criteria. - Project leader of a group of senior and junior level system analysts addressing the issues of placement on gate arrays (CAD/CAE), providing technical supervision, coordination, and training. Informally worked with junior (and new) programmers, doing some technical training and supervision. - Group Leader of a group of several senior level system analysts addressing the issues of hardware acceleration of semi-custom chip component placement algorithms, including design and implementation of computationally intensive advanced algorithms to be implemented in microcode, systems embedding, and a user friendly high level interface to the design engineer. - Work in the interactive editor group for a high-level correct-by-construction editor for full custom VLSI chip planning and layout. - Member of a team designing and implementing a layout verification package for fullcustom VLSI chips to be integrated with the Chipmaster. Package included electrical rules checking, device and net recognition, layout versus schematic checks, layout parameter extraction, interface to schematic capture systems, SPICE simulator, and digital system simulators; user interface, data structures and algorithms. - Computers used were the Intel Microprocessor Development System for the 8086, and the DAISY Logician (an 8086, 80286, or 80386 based engineering workstation) with MAESTRO and DAISY-DNIX operating systems; languages used were PL/M-86, C, and Metaware PASCAL. |
