HOST-COMPILED MULTI-CORE SYSTEM SIMULATOR 
=========================================

This is the release of the HCSim-1.0 simulator.

This folder contains abstract models of real-time operating systems (RTOS) and 
high-level multi-core processor models for full-system host-compiled simulation [1]. 


Building and installing:
------------------------

Build requirements:
  - SystemC version 2.2.0 or 2.3.0  http://www.accellera.org/
  - TLM 2.0 http://www.accellera.org/

Preparation before build:
  - Edit Makefile.macros. Set the following variables (external dependencies):
      SYSTEMC_DIR - to the installation directory of SystemC-2.2.0 or SystemC-2.3.0
      TLM_DIR - to the installation directory of TLM-2.0  

Build hcsim library:
  % make clean
  % make all


Running:
--------

Before run an example:
   % source <install_path>/bin/setup.sh
  
To run examples locally:
   % cd <example>
   % make test

<example> can be one of:
  - examples/simple_taskset
  - examples/mix_taskset
  - example/mix_taskset_tlm2.0
