In addition to writing, Forrest has designed and led the development of six hardware and software prototypes, including a prototype for a flat-panel handwriting and drawing device, a cost-accounting application marketed in cooperation with Microsoft, a file-conversion application, two audio synthesizers based on Intel neural-network chips, and several Java animations.

Forrest received an M.A. in City Planning and an M.A. in Architecture from the University of California at Berkeley. His city-planning thesis, on urban telecommunication networks, was written under the chairman of the EE/CS Department. His architecture thesis, on transportation networks, was written under the chairman of the Transportation Engineering Department. He received his B.S. in Design from the University of Michigan.

Forrest gave a presentation on Cities and Computers: Their Architecture at Stanford University and UC Berkeley. The presentation describes computer functions that work like city functions. The video is at: Cities and Computers Video

John Goetz

John Goetz has had a 23-year career at IBM as a microprocessor and computer-system architect, product marketing manager, verification-tool developer, and logic designer. He has written technical manuals and engineering specifications throughout his career, including documents about the Cell Broadband Engine (CBE), PowerPC, x86, and MIPS processor architectures, network processors, and reconfigurable logic. At Warthman Associates, John has written technical documents for AMD, PMC-Sierra, and Xilinx about the x86, PowerPC, and MIPS processor architectures, and for Infineon about industrial semiconductors.

Prior to Warthman Associates, John was at IBM for 23 years, most recently as a senior engineer in IBM's Global Engineering Solutions (GES) architecture group, where he architected embedded imaging solutions based on the Cell multiprocessor and ASICs for the aerospace, defense and health care industries, including CT, PET, MR, and ultrasound technologies. Before that, he taught high-school mathematics and wrote standard specifications for the RapidIO Trade Association. He was a senior engineer and marketing manager for IBM's Network Processor Business Line, where he defined new PowerPC-based products and positioned existing products for network applications. Before that he was a senior processor architect working on product strategy of system-on-chip (SoC) PowerPC products and x86 business relationships. He architected and led the verification of an operating mode for the PowerPC 615 processor that executed multiple instruction sets, and he served as the in-house consultant to IBM design and verification teams on all issues related to PowerPC and x86 instruction-set architectures. He was the principal editor of the engineering specification for the PowerPC 615 processor. Prior to that he managed the department responsible for IBM’s x86 processor architectures and verification. He began his career at IBM in electronic design automation (EDA), responsible for developing simulation and logic-synthesis tools.

He has five patents in areas including microprocessor cache design, multiple-instruction-set support, and logic-network optimization.

John received his B. S. in Electrical Engineering from University of Notre Dame, followed by masters coursework in microprocessor architecture and operations research at the University of Vermont.

Thomas Sidle

Thomas Sidle has broad experience developing, using, and managing the development of electronic design automation (EDA) tools for digital design and fabrication of computer systems, ASICs, FPGAs and other semiconductor devices. He has designed architectures, managed product development, and written code for more than twenty EDA tools. Along with this work he has written dozens of documents, including architecture specifications, marketing plans, implementation and coding plans, user references, and marketing collateral.

Prior to joining Warthman Associates, he was VP of advanced CAD technology research and director of advanced CAD development at Fujitsu Laboratories in California. In these roles he defined user requirements, specified technical architecture, and managed development of many EDA tools, including tools for logic synthesis, clock-tree synthesis, timing analysis, formal verification, logic-equivalence checking, design-for-manufacturing, UML-based electronic system-level design tools for hardware/software co-design. At Amdahl, he was principal marketing manager for telecom products and programs, principal product manager for corporate marketing, principal computer architect and planner, and manager of advanced design-automation development. During this time he developed products combining Sun SPARC servers with S/390 systems for data centers, led product-strategy development for UNIX mainframes, managed UTS UNIX and OS-enabling products, managed vendor relationships and the UTS UNIX third-party porting lab, formed the VLSI design-tools development department, developed the architecture for new mainframe EDA tools, promoted high-level design methods using VHDL and logic synthesis, developed a cycle simulator and system-verification methods for mixed-signal systems, and developed tools for design-rule checking, logic-synthesis, and timing analysis. Prior to that he was a technical staff member at Scientific Calculations, a project engineer at National Advanced Systems, and an engineering programmer at Burroughs. He holds one patent on invariant checking and is co-author of four other patent applications.

Thomas received his B.S. in Electrical Engineering and Computer Science from the University of California at Berkeley, and his M.S. in Computer Science from the University of California at San Diego.

Rob Johnson

Rob Johnson is an engineer and technical writer specializing in consumer-electronic product development. He has written many technical and developer documents for graphics processors, I/O chipsets, wireless network devices, process development, and software-quality engineering. He has also edited new-technology specifications for industry alliances supported by the IEEE Industry Standards and Technology Organization (ISTO), including the Mobile Industry Processor Interface (MIPI) alliance and the Linux Mobile (LiMo) foundation.

Before joining Warthman Associates, Rob worked at Intel where he developed software for new chipsets including the Intel®810 graphics and early Centrino™ wireless products. He architected and coded the video-capture drivers and interrupt subsystems for the graphics chipsets as well as bringing up the hardware. He also authored protocol-analyses and architecture proposals for Intel’s integrated wireless products. He was directly responsible for developing and writing programmer’s reference manuals for multiple chipsets, training materials for software-process improvement and innumerable reports, proposals, and other engineering documents, as well as leading product-development teams for Linux drivers. At GTG Productions, Rob created software for enhanced CDs that included disc and audio control and installers for such artists as David Bowie, Brian Eno, and Todd Rundgren. He also developed programmable high-performance ignition systems for Yamaha jetskis and an audio mixer plug-in for Macromedia Director®. Prior to GTG Productions, Rob developed toys for Hasbro®, Lionel®, and Chase Toys, including a GI Joe playset and the TrainMaster® Command Control system which was debuted at the Asilomar Microcomputer Conference. Previously, he was chief engineer for C & K Systems’ System238™ Residential/Commercial Security Panel, developing the hardware, software, and communication architectures as well as the product requirements, user’s guide, and product datasheet.

Rob attended Virginia Tech and Hayward State Universities before receiving his B.S. in Electrical Engineering from the University of Nevada, Reno. He has also taken coursework in program management, Linux driver development, software-development life cycles, patent development and product branding and trademarking. Rob is a cycling enthusiast, having ridden all over the world including the 2003 Tour de France route.
