RTG4 Radiation-Tolerant FPGAs

High-Speed RT FPGAs for Signal Processing Applications

Overview

RTG4 FPGAs integrate Microsemi’s fourth-generation flash-based FPGA fabric and high-performance interfaces such as serialization/deserialization (SERDES) on a single chip while maintaining the resistance to radiation-induced configuration upsets in the harshest radiation environments, such as space flight (LEO, MEO, GEO, HEO, deep space); high altitude aviation, medical electronics, and nuclear power plant control.

Configuration Immunity

RTG4 FPGAs are manufactured on a low power 65nm process with substantial reliability heritage. RTG4 FPGAs are now qualified to MIL-STD-883 Class B, and Microsemi will seek QML Class Q and Class V qualification.

RTG4 FPGAs are immune to radiation (SEU) induced changes in configuration, due to the robustness of the flash cells used to connect and configure logic resources and routing tracks.

No background scrubbing or reconfiguration of the FPGA is needed in order to mitigate changes in configuration due to radiation effects. Data errors, due to radiation, are mitigated by hardwired SEU resistant flip-flops in the logic cells and in the mathblocks. Single Error Correct Double Error Detect (SECDED) protection is optional for the embedded SRAM (LSRAM and uSRAM) and the DDR memory controllers. This means that if a one-bit error is detected, it will be corrected. Errors of more than one bit are detected only and not corrected. SECDED error signals are brought to the FPGA fabric to allow the user to monitor the status of these protected internal memories.

Design Resources

Space System Managers are companion devices that can be used with any Radiation-Tolerant FPGAs

Design Software	The RTG4 family of FPGAs are fully supported by Microsemi Libero® SoC design software, that guides the user through the FPGA design flow and provides seamless design tool integration, as well as project, data file, and log file management. Libero SoC Software is now available for download. The download links can be found in the Libero SoC Software Release Notes.
Software Licensing	RTG4 devices require a Libero Platinum license which can be purchased through sales. Contact your local Microsemi Sales Representative
Design Hardware	The RTG4 Development Kit provides space customers with an evaluation and development platform for applications such as data transmission, serial connectivity, bus interface and high speed designs using the latest Radiation-Tolerant High-Density High-Performance FPGAs family, RTG4. The development board features a RT4G150 device offering more 150,000 logic elements in a Ceramic package with 1,657 pins.
Prototyping Solutions	RTG4 PROTO FPGAs offer a development and prototyping solution than can be used for development and final timing validation of the flight design. As the RTG4 PROTO units use the same reprogrammable Flash technology as the flight units, the PROTO devices can be reprogrammed many times without removing them from the development board. RTG4 PROTO devices use the same silicon and the same packages as RTG4 flight-model FPGAs. RTG4 PROTO device programming is currently enabled in Libero SoC Design Suite. When designing for RTG4 PROTO, customers can use the same device setting in Libero SoC software as for flight models. The RTG4 PROTO prototype units have the same timing attributes as the RTG4 flight units, including support for the same speed grades as the flight parts. The RT-PROTO units are electrically tested in a manner to guarantee their performance over the full military temperature range. Prototype units are offered in non-hermetic, ceramic packages. The prototype units include “PROTO” in their part number, and “PROTO” is marked on devices to indicate that they are not intended for space flight. They are also not intended for applications that require the quality of spaceflight units, such as qualification of spaceflight hardware. RT-PROTO units offer no guarantee of hermeticity, and no Mil-STD-883 class B processing. At a minimum, users should plan on using class B devices for all qualification activities.
Programming & Debug	RTG4 is supported by FlashPro for in circuit programming, FlashPro4 and FlashPro5 both supported Factory Programming Services are also available
IP Cores	Search for RTG4 IP cores Microsemi offers many soft peripherals that can be placed in the FPGA fabric of the device. These include Core1553, CoreJESD204BRX/TX, CoreFIR, CoreFFT, and many other DirectCores.
Partners	Many of Microsemi’s Partners are engaged in development with RTG4 FPGAs
Power Analysis	Leverage our Excel based RTG4 Power Estimator to evaluate power for your design without running through the full design flow. RTG4 FPGA Power Estimator User Guide SmartPower can also provide design specific power analysis for your design implementation within Libero.
IBIS Models	Generic RTG4 IBIS Models are available for signal integrity simulations. Design specific files can also be exported from your design implementation in Libero.
BSDL Models	Design specific files can also be exported from your design implementation in Libero.
