• Hardware design included extensive full-custom CMOS design, layout, verification, and test; a CMOS gate array; and help with several board-level logic designs. 
  • Full-custom CMOS design included two generations of router chip, a bus-interface transceiver (BIX chip), and the SRAM and multiplier sections of several processor-element chips.  Several of these designs included some way-cool analog circuitry!
  • Did the layout of the BIX chip using Cadence Edge tools. 
  • The gate array (ChIL chip) implemented the I/O-channel protocol. 
  • Board design included the instruction-fetch section of the MP-1 control board, and the channel-interface sections of several I/O boards. 
  • Hardware experience also included leadership in the bring-up and debug of the MP-1, plus other guru-level h/w debugging, including transmission-line effects and some very subtle I/O-system e-mag problems. 
• Design-aid software included router architecture simulators, some Synopsys VHDL and CLI modelling, UNIX glue for inhomogeneous tools, and extensive Cadence Skill and DRC scripts for CMOS synthesis and verification.  Used Cadence Edge, Epic PathMill, and several Zycad logic- and fault-simulation accelerators. 
• Diagnostic software included comprehensive router and I/O-channel tests and MasPar's universal memory-test program met. 
• Learned data-parallel programming and wrote a 200k-crypts/s UNIX password cracker. 

1987 - 1988:  Contractor, Systems Science, Inc., Menlo Park, CA.
Wrote NECSIM netlist translator:  NEC proprietary formats into EDIF.  Compiler-like project included LEX and YACC, plus hash- and symbol-table, semantic analysis, and code-generator modules. 

1986 - 1987:  Contractor, Standard Microsystems Corp. (see below).
Helped with several projects while trying to establish a full-time California-based employment arrangement.  Tasks included yield improvement and process troubleshooting, plus back-end work on 84C19/28/29 DRAM controller and 84C02/03/04/05 ECC chip.  Did layout editing on a Calma GDS-II.  Wrote a switch-level logic simulator for the IBM PC. 

1984 - 1986:  Senior Engineer, Silicon Solutions Corp., Menlo Park, CA (subsequently Zycad).
System/board/chip design work on the MACH-1000 logic/fault-simulation hardware accelerator.  Learned simulation algorithms.  Wrote the architecture simulator for the accelerator.  Helped with design and layout of custom CMOS chips. 

1975 - 1982:  Senior MOS Design Engineer, Standard Microsystems Corp., Hauppauge, NY.
Started as Technician and was quickly promoted to Engineer.  Designed the following chips:

• 9216 and 9229 floppy-disk data separators
• 9003 floppy-disk controller
• 1863, 8017, and 8018 UARTs
• 8004 SDLC-specific CRC generator/checker
• 8046, 8116/26/36/46, and 8216 baud-rate generators
• Also worked on 1671 (Astro) and 5025/35 (SDLC) USARTs. 
• Other contributions included design of single-pin crystal oscillators for N- and C-MOS processes and software for finite-state machine emulation and circuit simulation.
