7.1 About SystemC Export with Multiple Instantiation

SystemC Export wraps the components of a SystemC-based virtual platform into an Exported Virtual Subsystem (EVS). Multiple Instantiation (MI) enables the generation and integration of multiple EVS instances.

SystemC Export with MI enables the generation of EVSs as first-class SystemC components:

  • Capable of running any number of instances, alongside other EVSs.
  • Providing one SC_THREAD per core component (that is one SC_THREAD per core component in a cluster Code Translation (CT) model).

MI enables the generation and integration of multiple EVS instances into virtual platforms with SystemC as the single simulation domain. A single EVS can appear in multiple virtual platforms. Equally, multiple EVSs can combine to create a single platform.

SystemC components (including Fast Models ones) can exchange data via the Direct Memory Interface (DMI) or normal (blocking) Transaction Level Modeling (TLM) transactions.

Fast Models supports SystemC 2.3.1, including integrated TLM 2.0.2. In this version, the TLM and SystemC headers are in the same place, and some filenames are different.

If you use them, set SYSTEMC_HOME and TLM_HOME to valid directories when running simgen. If the "include" directories do not exist when simgen runs, they cannot be in the include path.
