Saratoga Data Systems logo click to visit their site

December, 2007 to Present - San Jose, California

Brevard and Brevard is consulting in several roles* with Saratoga Data Systems, a small company with two products focused on dealing with ever increasing data size. Bantam can reorganize GDSII Stream (chip layout) data producing dramatic file size reduction without compression or any change to the original design function. Originally conceived as a solution for transmitting these, still very large, files Flume is an application level pure software solution providing dramatically faster data transfer over long distance, high latency networks. Beyond design data, Flume has since proven to be generally useful in many other situations including very challenged networks in use by the military. A close personal friend and industry veteran Arny Goldfein helped found this company and invented the technology in Flume. After his untimely death in June of 2007 I decided to help the company continue his work.


December, 2009 to Present - San Jose, California, and Austin, Texas

Brevard and Brevard is also working with JABIS Security in Austin, Texas.

The first project done for JABIS was a Microcontroller Product Selector Guide created for NEC Electronics and updated after their merger into Renesas Electronics America. This is a browser based stand-alone selector that can run from a CD or other file system - without a web server. It is implemented with JQUERY, css, JavaScript, and Dynamic HTML (DHTML) and tested with IE 7, IE 8, Firefox, Chrome, and Safari. A web server is not required but can be used if desired. All style elements were provided by the client's corporate css files - modified for use in a serverless environment.

The current focus is PDF based school site- and floor-plan information for emergency responders. We've now created several proposals for "information fusion" with additional integration including streamed security video and links to Google Earth, Twitter, and other external sources.

Strategic Market Development - Alliance Manager

November 3, 2004 to November 16, 2007 - Mountain View, California

I rejoined Synopsys in Strategic Market Development (home of various Interoperability Programs) as an alliance manager, initially for Compute Platforms. I worked with internal groups and external partners to define and promote the specific computer platforms (hardware and operating systems) on which Synopsys EDA software is certified to run. Starting in April 2005, I took over the MAP-in program that provides Milkyway database access to other EDA companies. I also wrote over 11,000 lines of C++ providing an initial Milkyway to OpenAccess schematic and layout importer for the product announced September 22, 2008 as Galaxy Custom Designer.


Cadence Design Systems - logo

Integrated Circuit Framework Technology Architecture

December 17, 2003 to October 25, 2004 - San Jose, California

After an intense month of pursuit (started by a head-hunter) and much soul searching, I accepted a position as an "Architect" at Cadence Design Systems in the IC Framework Technology group. Among other things, this is the home of the OpenAccess database. My first major project was a translator from Milkyway to OpenAccess - now in beta test. I last worked on performance and capacity analysis prior to the official release of OpenAccess 2.2.

This job entailed a relocation from Oregon to Silicon Valley. We bought a house in San Jose on January 16 and I started "camping" there on January 22. My CPA wife Stevalyn moved in June after completing her 2004 "Tax Season." And we sold our house in Oregon in July. All spring I got to live in the midst of various remodeling projects but we are finally settled in now.

Design Database Development and Standardization

August 2002 to December 2003 - Hillsboro, Oregon
September 2001 to August 2002 - Beaverton, Oregon

Milkyway is the database at the heart of the best-in-class physical (layout) semiconductor design tools originally developed at Avant! Corporation.

Avant! originally hired me to work on the technical aspects of opening up access to Milkyway - partly as a response to a proposal made June 2001 for the new OpenAccess API standard - http://www.si2.org/openaccess/

Using my background in electronic design data representation and my knowledge of standards processes, I worked on Milkyway specifications, documentation, presentations, and minor modifications to the code base - all to allow wider use of this technology by both customers and other EDA vendors.

I started at Avant! on September 17, 2001, with two weeks of training on the Milkyway design database in Fremont, California. I then settled into the Avant! Beaverton, Oregon, office on October 1, 2001. We moved to the Synopsys Inc. office in Hillsboro, Oregon, on August 12, 2002.

On June 4, 2002, Synopsys (the number two EDA company in sales at that time), purchased Avant! Corporation (we were number four). I ended up as a "Staff Engineer" at Synopsys, making many trips to the Sunnyvale, headquarters for Milkyway R & D.

We opened up Milkyway to other companies with a new program called MAP-in on February 3, 2003. Now almost anyone can get a FREE license to the Milkyway Environment with translators (Verilog, VHDL, GDSII, LEF/DEF, etc.), a graphical viewing and editing environment, scripting and access to Milkyway data via Scheme and Tcl. 

In 2003 the MAP-in program also released a C-API for use in stand-alone programs based on work that I did in 2002.


Consulting and Private Investments

7 Months: February 2001 to September 2001 - Austin, Texas

After leaving MediSpecialty.com (see below) I attempted to re-enter the world of Electronic Design Automation in one of the worst slowdowns ever in the semiconductor industry.

For six months I collected unemployment (for the first time in my life) while pursuing interviews that did not lead to job offers. In spite of my extensive background, all openings were being restricted to people with recent experience that exactly matched the positions.

Past savings, my wife's income, and investments allowed us to financially survive this period.

In July two people at Avant! Corporation with whom I had worked at MCC and Motorola realized that a new activity (see above) was starting for which I had a perfect background.

Major Contracts during this period

EDA

Internet


Microelectronics and Computer Technology Corp. (MCC)

EDA Research, Programming, and Standards Development

10 Years: June 1984 to December 1994 - Austin, Texas

MCC was started in the early 1980s by a group of electronics and computer companies to respond to the threat of the Japanese 5th Generation Computer Project. It was the first pre-competitive research organization allowed in the United States - literally taking an "act of Congress" to exempt it from previous anti-trust laws.

Ultimately the Japanese threat turned out to be insignificant and the rise of personal computers and ubiquitous use of Unix obviated the most of the purpose of MCC. It effectively shut down after about 10 years of operation.

I started in the VLSI CAD Program which initially developed a new EDA system from scratch in Lisp, later moved the research to Unix and the X Window System, and finally concentrated on EDA standardization efforts, mostly via the CAD Framework Initiative (CFI). CFI still exists today, renamed to Si2 and hosting the OpenAccess design database standard and reference implementation.

Developed design representation (DR) and simulation in Object Oriented Lisp systems.
Developed schematic capture systems on Lisp Machine and UNIX / X Window System.
Developed design representation standards with VHDL, EDIF, and CFI.
Developed DR standards prototypes and example applications.

Windows Experience

Windows and Unix System Integration Experience

At Motorola I evaluated then installed and configured the Tektronix WinDD version of the Citrix WinFrame multi-user NT system. Integrated with Unix file system via Samba (setup by Motorola Unix system administration), user authentication provided by optional NIS (yellow pages) integration.

This system used a dual processor HP Vectra XU Pentium Pro 200Mhz system to support 15 simultaneous users each with their own Windows NT 3.51 session.

In Austin, we had twelve systems on switched 10/100 network with a full time connection to the Internet via both Southwestern Bell ADSL (static IPs) and the Road Runner Cable Modem service (one dynamic IP with firewall / router). Mixture of Windows 2000, Windows 9x, Linux, and Solaris.

In Beaverton, Oregon, we had ten systems online with 100TX full duplex switched interconnect. Internet access was via DSL and cable modem: Verizon Business DSL provided 768K/128K ADSL with a block of 8 static IP addresses, 5 of which were usable. AT&T Broadband Internet provided cable modem service with a single IP shared via a Linksys BEFW11S4 NAT router, 802.11b access point.

In San Jose, California, there are approximately nineteen systems with GigE full duplex switched interconnect plus 802.11b/g/n wireless. There are 4 routers (one for each public IP address) and one additional wireless access point. Internet access is with Comcast Business Cable Modem service (12 Mbps / 2 Mbps) for both general Internet access and servers on 4 of 5 usable static IPs. The public servers are my mail, DNS, and web server, plus ca.saratogadata.com. In 2011 we decommissioned DSL from SBC with Sonic.net as my ISP that was my original source of static IPs.

In March 2013 we added AT&T's U-verse to provide a secondary Internet connection (and to replace the no longer bundled Comcast residential cable TV service).
