DDR2 license Question

The customer obtained the DDR2 license through the Altera website. Does this IP license have any time limitation or other usage restrictions? When generating the project for the EP4CE75U19I7N device...

Hi Aaron,

 

May I confirm whether the DDR2 IP license was purchased together with other licenses, or as a standalone license?

Based on the licensing behavior, a valid DDR license is not subject to time limitation. The time limitation only applies to FPGA IP Evaluation Mode, where Quartus generates a time-limited programming file  (*_time_limited.sof). 

For your project, 

  • Quartus generates project.sof successfully.
  • No project_time_limited.sof file is generated.

This behavior indicates that the DDR2 IP is being compiled with a valid, unrestricted license rather than an evaluation license. As a result, there are no project_time_limited.sof  which will expires within certain time limit is present. 

 

For your reference, I have attached a screenshot from the Altera FPGA IP Software Installation and licensing documentation that describes the licensing behavior of FPGA IP cores (https://docs.altera.com/r/docs/683472/25.3/altera-fpga-software-installation-and-licensing/questa-altera-fpga-edition-and-questa-altera-fpga-starter-edition-software-license)

As an additional check, the customer can review the Quartus compilation log for any OpenCore Plus or time-limited core messages, which would indicate that an IP in the design is running in evaluation mode.

 

Thank you.!
