System Plus Consulting has developed a powerful cost simulation tool to evaluate the cost of any LED device:

From single chip to complex structures

LED CoSim+ is a process-based costing tool used to evaluate the manufacturing cost per wafer using your own inputs or using the pre-defined parameters included in the tool. It is possible to enter any LED process flow or component. LED CoSim+ includes a comprehensive database:

  • Fab unit database
  • Equipment database
  • Consumables database
  • Wafer database
  • Process Flow database

Due to their particular manufacturing process (GaNepitaxy, specific packaging…), the cost of LED devices can be difficult to estimate. Components such as regular LED, High Brightness LED or Ultra High Brightness LED involve very different process steps. LED CoSim+ is a powerful cost simulation tool designed for the LED community featuring:

  • Highly flexible anduser-friendly hierarchical view where each process step can be moved, modified or deleted
  • Multiple process flows:

o Hierarchical description for multiple dies from different technologies or processes.
o Simulating cost according to different conditions (region, cleanroom , process, etc.)

  • Two calculation modes: for dedicated fabs and non-dedicated fabs
  • Integrated equipment, wafer & material databases
  • An unlimited number of process steps or process flows to store in libraries
  • Up to five simultaneous scenarios allowing the user to run sensitivity analysis and compare results like yield improvement, manufacturing location impact on cost, etc.
  • Multiple subcontracting operations: costs of usually externalized operations can be precisely evaluated by setting their individual regional and commercial parameters.



An optional Power process library and components library are available for some LED devices:

• The LED components Library includes front-end and back-end processes for some devices from Cree, Nichia, Citizen, Lumileds, Osram, Seoul Semiconductors, Sharp, Visera…

• The LED processes Library LED includes front-end processes only from Cree, Nichia, Lumileds, Osram, Seoul Semiconductors, Sharp, Visera, Semileds…

Do the tools include a component library?
The standard package doesn’t include a component library. But, you can add a component library with additional charges.


Do the tools include a process library?
The standard package doesn’t include any process library. But, you can add a process library with additional charges.


Since I have to detail all the process steps, do I get cost details at each step of the process?
Yes, our CoSim+ tools will provide you cost details at each step of the process.


How many process steps can I add to simulate my cost?
You can add unlimited process steps.


How can I learn to use the tools?
All tools include a helper. In CoSim+, you have a PDF file to guide you.
If needed, when you buy one of our tools, you can schedule a one-hour training session via WebEx with our engineer. You can also purchase an on-site training session if needed.


Which technologies can I simulate with LED CoSim+?
LED CoSim+ can simulate any LED technologies, including blue, red, IR and UV, including processes from Nichia, OSRAM, Lumileds, CREE, SETi and others.


Can I simulate the packaging with LED CoSim+?
Yes, the packaging is a part of the manufacturing process and you can simulate it with LED CoSim+.



What is the difference between the site license and the corporate license?
The site license is for all employees in just one location. The corporate license is for all employees from the same company worldwide.


Once I get the license, do I need to pay something else?
The license includes maintenance for the first year. After the first year, if you wish to keep receiving our support and updates, you will need to pay the maintenance fees only. It will cost between 1,000€ and 3,500€ depending on your license type and tool.


Why should I pay for maintenance after the first year? Can I get maintenance for free?
Thanks to the maintenance, you get updates to the tools and database every year. Maintenance also includes support from our team.

The first year, the update is included in the license fees. You don’t have to add any other fee. However, after this first year, you will have to purchase our yearly maintenance to get our tools and database updates.


Can I test the tools before buying it?
System Plus Consulting doesn’t provide any trial version but you can schedule a one-hour WebEx demo with the team to get a better understanding of which tool you might need.
