OpenCores design and publish core designs

"Our main objective is to design and publish core designs under a license for hardware modelled on the Lesser General Public License (LGPL) for software. We are committed to the ideal of freely available, freely usable and re-usable open source hardware."

OpenCores design and publish core designs

Subsidiary objectives
  • Develop standards for open source cores and platforms
  • Create tools and methods for development of open source cores and platforms
  • Develop open source cores and platforms
  • Provide documentation for these cores and platforms
These tools and methods should allow large, widespread, even international, teams to develop hardware in an open way.

UART to from fiber optic - OpenCores

UART to / from fiber optic

This core is well tested. They is two versions: -Fixed baudrate (0 to 2.5Mbit/s) - a full set of 2 transmitter and 2 receiver fit in a single XC9572XL CPLD -variable baudrate 50Mhz/n*p where n between 20 to 100 fiber optic baudrate and p>=1 baudrate divider.

Other Projects
  • Ethernet MAC 10/100 Mbps
  • USB 1.1 Host and Function IP core
  • OpenRISC 1000
  • CAN Protocol Controller
  • I2S Interface
  • SPDIF Interface

TinyCAD - Open-Source Schematic Capture

TinyCAD is a program to help you draw circuit diagrams. It comes complete with symbol libraries to get you started straight away.

TinyCAD - Open-Source Schematic Capture

TinyCAD - Open-Source Schematic Capture

Features to make it easier for you to put your circuit diagrams on your own web-site or adding them to your Word or other documents. TinyCAD supports outputing ciruits diagrams as PNG files.

Can be used to make circuit diagrams that can be fed in to a PCB layout program. You can export from TinyCAD in Protel, PADS, Eagle SCR format. You can also use TinyCAD to create Spice simulation files.

CMOS Mixed-Signal Circuit Design - R Jacob Baker

Some Chapters
  • Chapter 3 Analog Filters 73
  • Chapter 4 Digital Filters 119
  • Chapter 6 Data Converter Design Basics 203
  • Chapter 8 Bandpass Data Converters 285
  • Chapter 9 A High-Speed Data Converter 301
This book will fill a hole in the technical literature for an advanced-tutorial book on mixed-signal circuit design. There are no competitors in this area. Mixed-signal design is performed in industry by a select few gurus . The techniques can be found in hard-to-digest technical papers.· Data Converter Modeling· Data Converter SNR· Noise-Shaping Data Converters· Submicron CMOS Circuit Design· Implementing Data Converters· Integrator-Based CMOS Filters· At the Bench
