Cobham Gaisler provides high-performance behavioral simulators of the LEON processors. The simulators are developed for near real time performance and accurate behavior. Using the simulators, it is possible to develop and debug target applications before the real hardware is available, thereby shortening the product development cycle.
TSIM3 introduces new functionality such as multi-core models for GR740/GR712RC, Tcl frontend for easier automation, new IO models and improved APIs, GDB-8 support, and so on while still maintaining functionality and the accuracy profile of TSIM2 allowing efficient SW V&V development also for multi-core systems. TSIM3 is being released in stages and currently support stand-alone simulation. Upcoming releases will add support for using TSIM3 as a library, simulator state checkpointing, AHB split response modelling and more IO models.
TSIM3-LEON4 simulates quad-core GR740 and generic LEON4 systems, TSIM3-LEON3 simulates dual-core GR712RC, GR716, UT699, UT699E, UT700 and a generic configurable LEON3 while TSIM3 GR716 only simulates the GR716, TSIM3-LEON2 simulates AT697E and a generic configurable LEON2.
