ES910 Rapid Prototyping Module
In a small physical package, the ES910 Rapid Prototyping Module provides high computational throughput and a variety of ECU interfaces. It is built around a Freescale PowerQUICC™ processor that features hardware support for double-precision floating-point arithmetic. Target-close model simulation without the target's resource limitations is enabled by the microprocessor type, the AUTOSAR compliant RTA-OSEK real-time operating system, and the onboard non-volatile RAM (NVRAM).
The ES910.2 provides an ETK ECU interface and two CAN interfaces. For high-performance bypass prototyping, the ES910 can be connected to ECUs equipped with an ETK. For other prototyping needs, the two CAN interfaces can be used in both high- and low-speed mode.
INTECRIO users can develop new control and diagnostic functions in MATLAB®/Simulink® or ASCET-MD, create an executable, and configure the ES910 as prototyping hardware. Once the executable is downloaded into the ES910, users control the behavior of the model at runtime from the INTECRIO experiment environment. Verifying the timing behavior of newly developed functions being executed on the ES910 can be accomplished in parallel with the RTA-TRACE software logic analyzer in real-time.
INCA users who want to do rapid prototyping with the ES910 use the INCA-EIP add-on to integrate the ES910 as a simulation target with INCA. The preconfigured ES910 simulation target then behaves like an ECU with measurement and calibration access. With INCA, the ETK ECU interface of the ES910 can be used for ECU data acquisition or ECU calibration, e.g., in an ES910 bypass experiment. In parallel, INCA can be used in the vehicle or at the test-bench to acquire data from other ECUs, buses, and sensors.
ES920 FlexRay Module
With the new ES920 FlexRay Module, the ES910 becomes a FlexRay node in no time at all. The interface features two FlexRay channels, conforms to FlexRay Specification V2.1, and meets the quality criteria of the FlexRay conformance test (ISO 9646). To optimize the data throughput between FlexRay bus and ES910 simulation controller, the ES920 Flex-Ray Module features an onboard preprocessor.
The roundtrip time that passes between the reception of a FlexRay signal and the return of a response signal to the bus is than 100 microseconds. Accordingly, with typical time slot widths ranging in the static segment of 50 μs, the ES910 module is capable of transmitting a response only a few time slots after receiving a message within the same FlexRay cycle. The ES920 module automatically assigns FlexRay messages to the model’s signals on the basis of the channel, cycle, and time slot attributes defined in INTECRIO. This means that the simulation controller is not called upon to provide machine time for processing raw FlexRay data.
