SNF – What the Hell is That?

SNF is an ultra-high performance model of a network system interconnect fabric that enables fast and accurate communication amongst computational elements of distributed systems. No longer is the performance and accuracy of your distributed system models compromised by slow, inaccurate network buses.

More Formally

System Network Fabric (SNF) is EST's ultra-high performance network modeling technology that enables the construction of communication facilities amongst interconnected autonomous modules (controller models) and subsystem models.

SNF uses EST’s protected simulation technology to provide a timing accurate, ultra-high performance, distributed model of a network. The first implementations are of the CAN and LIN buses. The FlexRay and MoST buses will follow.

So What Does SNF do?

Enables the interconnection of autonomous modules (controller and computation models) and subsystems into an ultra-high performance model of a distributed system.

Why is it a Benefit?

• Highest performance, timing accurate, distributed system network fabric model in the world.
  
• Enables the building of ultra-high performance models of systems.
  
• Provides a verification path that enables models and physical realizations of models to be validated in the same context:
  This is a remarkable capability

What Problem Does it Solve?

• The ability to build accurate distributed system models that have ultra-high simulation performance.
  
• Enables the full verification of distributed systems.
  

Examples

• Can bus model
  
• Lin bus model
  
• Coming:
  - CAN and LIN bus controllers
  - FlexRay and Most bus models and controllers
  

Who Should Use it?

• Companies that require high performance models of distributed embedded systems.
  
• System architects - for constructing optimized executable specifications of systems.
  
• Engineers who design the communication infrastructure between controllers in a distributed system.
  
• Verification engineers who need to verify distributed systems.
  
• Production engineers who need to validate physical product component against the executable specification:
  This capability is in the context of validating a product component incorporated, as a module, into a simulation of the entire system (that is the context in which the component must operate).
