Renesas Electronics Delivers Next-Generation Emulator That Contributes to Reduced Embedded Software Development Time
Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, announces the E2 Emulator, a new-generation on-chip debugging emulator. The E2 is intended as a development environment for the latest devices in the Renesas RH850, RX, and RL78 Families of microcontrollers (MCUs), and for a selection of automotive system(s)-on-chip (SoCs). The new emulator supports the extended debugging functionality of the RH850 Family and contributes to shortening the time required for CAN communication debugging and the current consumption debugging.
Recently, use of electronics for automotive control is increasing to improve the fuel efficiency, safety, and comfort of vehicles, and the number and variety of built-in sensors is growing. This leads to an increased size of control programs of MCUs used in electronic control units (ECUs). Since each ECU performs communication control via automotive networks such as CAN, LIN, and FlexRay®, and dozens of ECUs are installed in a single vehicle, communication control has become more complicated. Additionally, considering that many ECUs are installed in a vehicle, it has become more important to precisely understand current consumption when each ECU operates and optimizes the control programs to achieve low current consumption in automotive systems.
Key features of the new E2 Emulator:
(1) Download speed up to twice as fast
The new E2 Emulator features faster communication speeds between the MCU and emulator and parallelization of flash rewriting and data communication. These capabilities enable control program downloads up to twice as fast as Renesas’ existing E1 Emulator.
(2) Industry’s first solution that combines instruction-level debugging with CAN communication monitoring
As a CAN communication debugging function, the new E2 Emulator can stop the program when it detects that the interrupt response time has exceeded a specified limit, and record and display trace data relating to CAN communication reception and interrupt response processing simultaneously. The debugging function is provided as an industry first solution for measuring CAN communication response time that allows for clearer correlation between CAN communication and program operation.
(3) Easier determination of the cause of current consumption peak
The new E2 Emulator can detect the current consumption peak and stop the program when the emulator detects that the current consumption has exceeded set limits for a certain period of time. This allows system developers to determine the conditions in the program that cause it to exceed the expected current consumption levels. Additionally, the emulator can display the program operation and current consumption together, making it easier to identify areas where current reduction should be targeted. This shortens the tuning time for reducing current consumption.
The E2 Emulator is available now for the RH850 Family and a selection of automotive SoCs. The new emulator will be available for the RX Family and RL78 Family from July 2017 onwards. Additional debugging solutions for the E2 emulator will also be available from July 2017 onwards.
