Abstract
AbstractDuring the development of flight software, the processor emulator and satellite simulator are essential tools for software development and verification. SWT/KARI has developed the software-based spacecraft simulator based on TSIM-LEON3 processor emulator from Aeroflex Gaisler. But when developing flight software using TSIM-LEON3, there is much limitation for emulation of real LEON3-FT processor and it is difficult to change or modify the emulator core to integrate FSW development platform and satellite simulator. To resolve these problems, this paper presents the development of new GUI-based and cycle-true LEON3-FT processor emulator as LAYSIM-leon3 and describes the software development and debugging method on VxWorks/RTEMS RTOS.KeywordsLEON3LAYSIM-leon3emulatorISSCycle-TrueGUI based
