Introduction

Derived from Accellera SystemC 2.3.1, this library enables Out-of-Order Parallel Discrete Event Simulation (OoO PDES) for SystemC model simulation on multi- and many-core architectures. This software provides the simulator component of the Recoding Infrastructure for SystemC (RISC).

Use this all at your own risk! (Yes, it's a running gag!)

Installation

As an integral part of the RISC software, this OoO PDES library is installed together with the other RISC components. Please refer to the RISC installation instructions.

Configuration

• Environment variable SYSC_PRINT_MODE_MESSAGE can be defined to print the current simulation mode used.
• Environment variable SYSC_PAR_SIM_CPUS can be set to the number of CPU cores available for parallel use.
• Environment variable SYSC_DISABLE_PREDICTION can be defined to disable prediction optimization during simulation.
• Environment variable SYSC_SYNC_PAR_SIM can be defined to force synchronous PDES (no out-of-order execution).
• Environment variable SYSC_VERBOSITY_FLAG_1 can be defined to print logging information about thread states.
• Environment variable SYSC_VERBOSITY_FLAG_2 can be defined to print logging information about event notifications.
• Environment variable SYSC_VERBOSITY_FLAG_3 can be defined to print logging information about waiting threads.
• Environment variable SYSC_VERBOSITY_FLAG_4 can be defined to print logging information about what threads an event triggers.
• Environment variable SYSC_VERBOSITY_FLAG can be defined to enable all logging information listed above.
• Environment variable SYSC_NUM_INVOKERS can be defined to set the number of invoker threads for method processes.

Status

Version

Version 0.6.3.

Limitations

This is an academic proof-of-concept prototype implementation, not commercial-quality software.
