CoFluent Studio "Y" Design Flow |
CoFluent Studio™ can be used to model and simulate the behavior, timing requirements, architecture and performance estimates (loads, power, memory, cost) of any electronic system: HW IP, embedded SW application, mixed HW/SW multiprocessor system. Use cases of the system are also 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 parameters to easily adjust its behavior and performance characteristics.
CoFluent 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.
CoFluent Studio offers full flexibility in architecture exploration through the mapping of system functions to platform execution resources for describing the complete hardware/software system, and the variation of various user-defined or pre-defined parameters. |
CoFluent Studio is an integrated Electronic-System-Level modeling and simulation environment composed of:
| - A graphical modeler for capturing the system’s 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 OSCI SystemC 2 and TLM libraries) constituting the computation (multiprocessor, multicore, multitask) and communication (message queues, events, busses, interconnects, networks) simulation engine at the heart of CoFluent Studio
|
| CoFluent Studio targets complex multiprocessor systems with rich application content, whether they are: | - Multi-board (large equipments, distributed/networked systems)
- On-board (embedded systems)
- On-chip (SoC, FPGA, ASIC, ASSP)
|
| CoFluent Studio targets: | - Multimedia applications for the consumer electronics and telecommunications/networks domains
|
|
| | | 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 |
