Fields of Work

FRUCT, 2009-04-29


Two different FPGA based prototyping platforms are available:

• FFP Basic ( equipped with Xilinx Virtex-IIpro FPGA)

• FFP Basic+ ( equipped with Xilinx Virtex-5 FPGA)

Hardware extensions are available for both types of prototyping platforms:

• Pluggable add-on modules for several applications ( DAC, ADC, Gbit Ethernet, DSP)

• Development of customer-specific add-on modules

FPGA Building Set

Well-approved prototyping platform FFP Basic
