Intel® CoFluent™ Studio

Intel® CoFluentTM Studio requirements diagram


Intel® CoFluentTM Studio can be used to model and simulate the behavior, timing requirements, architecture and performance estimates (throughput, latency, load, power, memory, cost) of any electronic system: HW IP, embedded SW application, mixed HW/SW multiprocessor system. Use cases of the system are modeled so the automatically generated transaction-level SystemC code can be used as verification testbench.

Behaviors are described with intuitive graphical notations and ANSI C/C++ code, although algorithms can be left undefined and abstracted to their sole execution time. Platforms are built by assembling generic models of universal components like processors, integrated circuits, memories, busses, interfaces. Each generic model provides variable design parameters to easily adjust its behavior and performance characteristics.

Intel® CoFluentTM Studio allows for behavioral and performance estimation without the need for embedded software application code, firmware, or a precise description of the platform with models of each component/IP core.

  • No hardware IPs are needed
  • No embedded software is needed
  • No firmware / OS is needed
  • No ISS is needed


Intel® CoFluentTM Studio is an integrated Electronic-System-Level modeling and simulation environment composed of:

  • A graphical modeler for capturing the system's use cases, behavior and execution platform (the frontend)
  • A simulation framework for automatically generating and instrumenting a transaction-level SystemC model of the complete system (including HW/SW partitioning) and interpreting simulation traces with a rich set of analysis tools
  • A SystemC library (extending the Accellera SystemC 2 and TLM libraries) constituting the computation (multiprocessor, multicore, multitask/multithread) and communication (message queues, events, busses, interconnects, networks) simulation engine at the heart of Intel® CoFluentTM Studio
  • A DML code generator for translating graphical models into fast functional models for the Wind River Simics* simulation platform


Intel® CoFluentTM  Studio targets complex multiprocessor systems with rich application content, whether they are:

  • Multi-board (large equipment, distributed/networked system)
  • On-board (embedded system)
  • On-chip (SoC, FPGA, ASIC, ASSP)


Intel® CoFluentTM Studio for Timed-Behavioral Modeling

  • Targeted at system/specification engineers, application modeling/testbench developers and software engineers
  • For modeling and simulating the behavior and time properties of electronic applications with simple graphics and C/C++ code
  • For automatic generation of SystemC  or DML timed-functional model
  • For obtaining timed-executable specifications of the application for further system architecting or implementation

Intel® CoFluentTM Studio for System Architecting

  • Targeted at system architects and software architects
  • For exploring prospective system architectures (application-to-platform) and predicting their performance and power consumption
  • For obtaining a virtual system (platform + application) description in transaction-level SystemC serving as executable specifications for further hardware/software design and implementation

Intel CoFluent Studio allows developers of electronic systems and chips to:


Problems 80% cost-impacting decisions are taken in project's first 20% with few data
Current processes can't cope with growing complexity and time-to-market
Existing tools only help verify late in projects already made choices
Cost to fix late design errors is prohibitive
Solutions Securely predict behavior and performance from partial software and hardware for design validation at all stages
Advantages Run short iterations for taking the right decisions at the right time
Validate choices and detect errors earlier
Optimize the system's architecture
Benefits Mitigate risks of project delays and cancellations
Reduce development time
Decrease bill of materials


Problems Too large gap from specification to implementation
Hardware & software engineers have no common understanding
Difficult communications between multicultural and multidisciplinary teams across distributed sites
Ambiguous specifications lead to misinterpretation and incompleteness
Difficulties to define subsystems and manage subcontracted work
Solutions Provide system executable specifications rather than static documents for common hardware/software reference
Advantages Facilitate implementation
Foster and organize teamwork
Ease interactions between all project stakeholders
Benefits Reduce development time
Mitigate risks of project delays and cancellations


Problems Little to no reuse of non-implementation work
Projects at risk if loss of key contributors
New projects can't benefit from past experience/expertise
Solutions Capture projects' system design expertise in enterprise model libraries for easier and faster innovation
Advantages Build a knowledge repository from project to corporate level
Reduce organizations' dependency on individuals
Accelerate new and derivative/maintenance project inception
Benefits Increase new product introduction rate
Mitigate risks of project delays and cancellations
