MIL-STD-1553 IP Cores with Cybersecurity and Wirefault Detection and Location

Sital Safe and Secure 1553 IP Core

Sital’s patented Safe and Secure (SnS) technology provides continuous real-time cyber authentication and wire fault detection.

Sital is the only MIL-STD-1553 supplier capable of detecting and locating open and short circuit electrical faults in bus or stub wires, connectors, couplers, terminators, and LRUs.

The BRM1553D-CS IP core provides continuous real-time cyber authentication. It can detect and locate intermittent or continuous open and short circuit electrical faults in bus or stub wires, connectors, couplers, terminators, and LRUs.

Low-power Transceivers

Sital’s IP is complemented by its own transceivers. Sital’s MIL-STD-1553 transceivers offer the industry’s lowest power consumption and dissipation. Sital can supply either packaged transceivers or transceiver IP (design documentation).

Sital’s IP cores can also operate with transceivers and transformers from other suppliers. Sital’s IP has passed RT validation testing performed by several third parties.

For use with its MIL-STD-1553 transceivers, Sital also offers a line of low-cost non-QPL isolation transformers complying with MIL-PRF-21038/27E electrical specifications.

he transformers are drop-in replacements for industry standard transformers. These are available in multiple configurations including single and dual, through-hole, and surface mount. They also support either transformer-coupled only or both transformer-coupled and direct-coupled configurations.

Sital offers a cost-effective option to supply complete bundled nodes consisting of its MIL-STD-1553 IP, transceivers, and transformers.

DO-254 and DO-178

For civil aircraft flight-critical systems and certain military applications, Sital can supply its IP and components with DO-254 certifiability artifacts up to and including DAL A (DO254-BRM1553D). Sital can also certify its software drivers with DO-178 up to and including DAL A.

IRIG-106 Chapter 10

Sital’s MIL-STD-1553 monitor includes an option to format monitored data in accordance with IRIG-106 Chapter 10, which defines a standardized file format used for data recorders.

Turnkey solutions

As a means for providing a turnkey solution and reducing customers’ design schedules, Sital offers its “Integrated 1553” integration service for SoC (system-on-chip) FPGAs. For example, Sital can integrate one of its single-instance or multi-instance IP cores with an on-FPGA processor over an on-chip bus such as AXI. This integration also comes with the API/library and low-level driver software specific to the customer’s operating system and on-chip bus. For a Xilinx FPGA, this would leverage Xilinx’s Vivado design suite.

Minimizing logic resources

Sital’s 1553 IP cores minimize the amount of required FPGA or ASIC logic resources by including synthesis compiling options for any combination of BC, RT, and/or Monitor modes. In addition, cores can operate with a selection of 4K, 8K, 16K, 32K, or 64K words of shared memory.

The BRM1553D features a high-speed synchronous interface to dual port shared RAM and internal registers. This includes a selectable input clock frequency that Sital can configure its core for in order to match customer requirements.

Many variations

Sital can supply cores with either a single instantiation or multiple instantiations. In addition to the BRM1553D base version, Sital can also supply the following:

• BRM1553PCI –  A version with a built-in PCI target back-end interface
• BRM1553SPI – A SPI back-end interface
• BRM1553FE – Most compact Cores, RAM free 1553, for use in simple system applications.
• BRM1553ERL – A version with SEU mitigation features for use in space applications

Future-proof Netlist

Sital’s IP cores are provided in vendor independent VHDL netlist that target all FPGA manufacturers families. The cores are supplied with simulation scripts, test bench code, and a 1553 bus tester VHDL model.

API/library and driver software

Sital supplies API/library software with its IP cores. There are also OS drivers available for VxWorks, Linux and Windows. Further, Sital can supply drivers for other real time operating systems as required. Another option Sital offers is its “Integrated 1553” integration service for SoC (system-on-chip) FPGAs.

For example, Sital can integrate one of its single- or multi-instance IP cores with an on-FPGA processor over an on-chip bus such as AXI, along with its API/library and low-level driver for the operating system and on-chip bus. For a Xilinx FPGA, this would leverage Xilinx’s Vivado design suite.
