Safety design kit helps ease development for safety-critical applications



Texas Instruments, in collaboration with Hitex Development Tools, introduced the SafeTI™ Hitex Safety Kit, enabling developers to evaluate SafeTI components for use in their designs requiring compliance to functional safety standards such as ISO26262 and IEC 61508. The state-of-the-art kit provides an example system with capabilities for hardware fault injection, application and run-time profiling of fault diagnostics and system response monitoring in real-time. The SafeTI Hitex Safety Kit enables customers to easily evaluate performance of SafeTI components for use in their safety-critical designs. The cost-effective hardware platform allows customers to evaluate the individual TI hardware components, either Hercules™ TMS570LS31x microcontrollers (MCUs) or RM48x MCUs and TPS65381-Q1 power management integrated circuit (PMIC) - with TI's Hercules SafeTI Diagnostic Library. Features and benefits of the SafeTI Hitex Safety Kit: · Enables customers to evaluate SafeTI components for potential use in designs requiring functional safety and targeting compliance to functional safety standards such as IEC 61508 and ISO 26262. · Integrates key capabilities for fault injection, application of diagnostics, reaction monitoring and run-time profiling of fault diagnostic routines for the example system. · Provides a demo software application which can be used as a starting point for evaluating TI Hercules MCU and PMIC combination chipset. · Offers a user-friendly, host-based graphical-user interface (GUI) that provides capability to inject faults, apply diagnostics, profile run-time of fault diagnostics, time-stamp system response and set configurations; and communicates with the development board to request status information enabling visualization of system response timing. · Includes a second MCU on the evaluation board, which acts as test control and monitor unit, and manages communication with the GUI. · Includes an on-board JTAG emulator, accelerometer, CAN transceiver, LCD module, temperature sensor and host/debug interface with a USB HUB controller and a serial communication port converter. · Utilizes an industry-standard DIMM form factor with 100-pin connector footprint for plugging into select TI motor control kits. · Supports use of select non-TI third-party debug tools with a 20-pin external JTAG header for further design flexibility. · Includes user-friendly documentation including a quick-start tutorial, user's guide, hardware schematics, and documentation for the diagnostic library to help ease evaluation and kit use. · Provides easy-to-use SafeTI Hercules software framework, which makes it easy to start development of safety-critical applications using SafeTI components. The SafeTI software framework includes: o HALCoGen, a GUI-based code-generation tool o SafeTI Hercules Diagnostic Library, offering a simple interface and a framework for enabling safety diagnostics/features recommended by the safety manuals of the Hercules MCU and the TPS65381-Q1 PMIC. o Evaluation version of SAFERTOS® from Wittenstein High Integrity Systems. · Includes well-documented source code for the demo application, the monitoring application and the diagnostic library. · Provides latest version of TI's Eclipse-based Code Composer Studio™ IDE for use with the emulator.
