Description
The goal of the CernFIP project is to provide a radiation tolerant
FPGA-based replacement for Alstom 's
WorldFIP agent, the MicroFIP chip.
This replacement is called nanoFIP.
The
is a rad-tol FPGA that acts as a client node in the communication over
the WorldFIP fieldbus.
It is housed in a Microsemi ProASIC3, A3P400, 208
PQFP FPGA.
The nanoFIP implements a minimal subset of the WorldFIP
services and is designed to be radiation
tolerant by using different SEU mitigation techniques such as TMR
and fail-safe state machines.
It is used in conjunction with a FielDrive driver chip and
FieldTR insulating transformer, both available from the
company Alstom.
