Sital Extends the MultiComBox Tester with EBR 1553 Capabilities

Posted on by Sital_web3D

EBR-1553 is a 10Mbps bit rate protocol which utilized the robust Mil-Std-1553 protocol over RS-485 transceivers in a hub-based point-to-point connection. Using the network topology of a star between Remote and BC Terminals allows robust and high-speed data transfer.
EBR supports various modes of operation – “SPEC” mode, “SWITCH” mode and “LINK” mode.

SPEC mode is similar to the standard 1553 protocol, where the BC sends the message in all ports, all RTs receive the message, and only the RT with the appropriate RT address should respond.

In SWITCH mode the BC sends the message only on the port where the particular RT is connected. For example, if a message is intended for RT 6, then it will be transmitted only on port 6, and the message will contain the RT address 6.

In LINK mode, the message is transmitted only on the appropriate port which corresponds to the required RT address (for example – port 6), but the RT actual address on the message command is ‘0’ for all RTs. This means that any RT that receives a message in this mode, with the RT address ‘0’ should answer to the message. Therefore, RTs are physically connected to the corresponding ports on the BC.

In MultiComBox Sital supports all three modes of operation.

Sital Integrates Wiring Fault Detection Capabilities Into it’s BRM1553 MIL-STD-1553 IP Cores

Posted on by Sital_web3D

Sital Technology Ltd. announced today that its patented technology for detecting wiring faults will be integrated into its BRM1553D, BRM1553FE and BRM1553PCI Mil-Std-1553 IP cores and boards.

Sital’s Passive TDR (pTDR™) technology is capable of detecting wiring problems such as disconnections, short-circuits, and others, whether they are constant or intermittent. pTDR is a Passive Time Domain Reflectometer (TDR) technology, which constantly measures reflections of energy on an operating Mil-Std-1553, CAN or similar bus. pTDR technology runs during normal system operation without disturbing the standard bus activity.

A standard TDR device sends pulses of energy to the bus and measures the reflected signal. Reflections are created from wiring faults such as disconnections, shorts or lack of proper termination. The time it takes for the signal to travel to the fault and back to the TDR is related to the location of the fault. However, a TDR cannot run while the system is operating, simply because it would be confused by the on-going transmissions on the bus, and also because it may disturb the standard communication.

pTDR does not transmit any pulses to the bus. Instead, it monitors the existing communications and measures reflections created by the normal transmissions. If there are wiring faults then signals will be distorted in certain ways that are related to the location of the fault. The main distortion is related to the width of transmitted bits. For example, in Mil-Std-1553 bits width is 1uS. A distorted bit can last for an additional few nano-seconds, according to the location of the fault. pTDR measures the distortions and reports the additional length of each bit. We call this additional length a “tail”.

The Sital pTDR system constantly reports tails from all Remote Terminals (RTs) on the network. In a correctly performing bus the tails from all RTs will be small and uniform. Changes in the tails indicate a bus fault.

Tail measurements are constantly performed on every message and updated on every frame. Therefore, even a very short disconnection event will be reported.

“The current situation is that each system on the aircraft performs its own built-in-test (BIT) and reports its own problems. But there is no mechanism for performing BIT to the bus wires or reporting wiring problems when they occur.” said Ofer Hofman, Sital’s CTO. “Our technology adds a great level of reliability to the bus, without interfering with the bus activity and without adding any complexity to the system.” He added.

Duli Yariv, Sital’s VP Marketing and Sales said: “Our pTDR™ technology is already implemented on CAN bus and used by automotive manufacturers for detecting wiring faults on vehicles during manufacturing, maintenance and operation. We are excited to enable our avionics and automotive customers to enjoy this technology, add value to their products and make safer aircraft and vehicles.”

pTDR technology for detecting wire faults will be available on the full range of Sital products: testers, IP cores and interface boards.

Sital Extends it’s BRM1553 IP with Error Injection Testing Capabilities

Posted on by Sital_web3D

Until now, BRM1553 IP cores delivered to customers were mainly targeted for in-flight applications. This means that no errors are allowed to be generated from the system.

However, a recent customer application required Mil-Std-1553 testing capabilities from an already-existing flight system, so that the same system can be used as a bus simulator on the ground or as an in-flight operational system.

Multi-RT feature is an essential feature for a Mil-Std-1553 bus simulator. It means that a single 1553 node can be programmed to act as many 1553 Remote Terminals. The user can program the Remote Terminal (RT) addresses which are simulated and thus the unit will answer and create messages, as requested by a Bus Controller (BC) for the simulated RTs.

The Error Injection feature enables the system to simulate several types of errors which may occur on a 1553 network. Therefore, errors like Parity Error, Sync. Error, Zero-Crossing Error and others are all part of an advanced 1553 test and simulation system.

Same Hardware for Interface Card and Test Benches.

Many avionics vendors, who develop avionic systems, are required to provide test benches for their systems. In many cases, developing the test bench is a high cost project, requiring development of boards, software and other simulation tools, usually at low volumes. Therefore the advantages of developing a single hardware that can be used both as a flight system and as a bus simulation tool are obvious. First – there is only need to develop a single hardware, and not require equipment from additional vendors for bus simulation and testing. Second – customers can re-use the software written originally for the actual system also for testing, ensuring lower development cost and enabling faster time to market.

Of-course, the customer needs to make sure that the test software is not loaded into the operational systems. This can be achieved by having a separate FPGA load file for each system and also by enabling or disabling the Multi-RT and Error Injection features by hardware. This means that the IP core can enable or disable the features, by reading hardware configuration bits, which are set differently between the tester and the in-flight system.

Both features can be added to Sital’s standard BRM1553D, BRM1553PCI and BRM1553FE Mil-Std-1553 IP core and are provided with software API, so that users can easily implement these test features into an existing Mil-Std-1553 system.

PCI-to-MIL-STD-1553 IP Core

Posted on by Sital_web3D

The newly released PCI IP core was developed in order to overcome problems related to existing BRM1553D,BRM1553FE and BRM1553PCI IP cores, specifically in the aerospace industry, where high reliability, wide temperature range and easy integration are key.

Ofer Hofman, CTO of Sital said: “While working on a project with a PCI core from one of the FPGA vendors, we discovered that the core we used doesn’t work in high temperature, even though the temperature was within the range of the component. We concluded that this is due to timing problems created by the core.

Another FPGA vendor provided us with a core that was very hard to integrate. We therefore used our extensive now-how and developed our own core, which is now successfully used in several projects”.

The core can be used for any FPGA and is provided in VHDL source code.
