Abstract

LEON3 is a 32-bit processor core conforming to the IEEE-1754 (SPARC V8) architecture. It is designed for embedded applications, combining high performance with low complexity and low power consumption. TSIM2 is a simulator that can emulate LEON3 based computer systems. It can also emulate user specific system-on-a-chip solutions by means of loadable modules. TSIM2 allows emulation of the LEON3 processor core with a completely user defined memory and I/O architecture. The emulated processor core communicates with the AHB module using an interface similar to the AHB master interface in the real LEON3 VHDL model. The AHB module can then emulate the complete AHB bus and all attached units. This paper presents simulation of vehicular application using LEON3 environment (TSIM2). The application includes wiper control and temperature control of AC in vehicle.
