Why OpenVizsla?

OpenVizsla hardware is mainly composed of four chips connected together:

  • FTDI FT2232H High-Speed USB FIFO
  • Xilinx Spartan 6 LX FPGA
  • Micron MT48LC16M16A2P-xx SDRAM
  • SMSC USB3343 ULPI PHY

Board Description

OpenVizsla

Specification:

  • communications with the FT2232H over USB using a proprietary USB protocol
  • FPGA configured with Slave SelectMAP
  • communications with the ULPI PHY layer compatible with ULPI and UTMU+ specifications
  • open-source software for validation purposes – ovctl

OpenVizsla features great developer experience by building firmware with Xilinx ISE Webpack toolchain.
