Emulator speeds up CAN and power consumption debugging

February 09, 2017 // By Julien Happich
The E2 Emulator announced by Renesas Electronics is an on-chip debugging emulator intended as a development environment for the latest devices in the Renesas RH850, RX, and RL78 Families of MCUs, and for a selection of automotive SoCs.

Renesas has integrated additional debugging features required for software development as solutions into the E2. Specifically, the new emulator reduces the time required to determine the cause of an error during CAN communication by providing a connection to the bus that allows message timing to be matched with executing code; it also makes it easier to determine the cause of current consumption peak by monitoring the current draw of the device and correlating that with the code. This enables system developers to potentially reduce development time in these areas to as little as one-tenth compared with the existing method of repeated program modification and downloads. Even when the modification/download cycle is necessary, the increased download speed of the E2 lessens its impact on the speed of the development cycle.
