IECUBE for RL78 Family
The IECUBE for RL78 Family is a high-Performance full-spec emulator for RL78 Family MCU.
It provides high-performance debugging functions such as time measurement, coverage, and trace.
In addition, a self-testing function detects faults in the IECUBE and performs maintenance.
