Description
The goal of the CernFIP project is to provide a radiation tolerant FPGA-based replacement for the MicroFIP chip, a WorldFIP agent.
This FPGA replacement is called https://www.ohwr.org/600
The nanoFIP is an Actel FPGA component implementing the WorldFIP protocol that can be used in field devices.
The component is developed as part of the WorldFIP insourcing
project and is designed to be
radiation tolerant
by using different single event upset mitigation techniques such as
triple module redundancy. To improve the radiation tolerance,
the nanoFIP implements a minimal subset of the WorldFIP services.
WorldFIP variables are transferred either directly on 16-bit I/O ports
or via a triplicated memory included in the nanoFIP component.
The device is used in conjunction with a FielDrive driver
chip and FieldTR insulating transformer, both available from
the company ALSTOM.
The project has been organized in work packages. The description of each package along with its status is described in the following table:
