DDR2 IP Qusetion in quartus 13.0 - DDR2 IP Qusetion in quartus 13.0 Hello I recently used Quartus13.0 to create DDR2 IP. I would like to ask the following questions. Q1 : I used MegaWizard Plug-In Manager to create a DDR2 Controller (as shown below). Do I need to pay for the use of this IP? Q2: Can the purpose of creating this IP be understood as the communication interface between FPGA and external DDR2? Q3 : The following picture shows the instantiated DDR2 IP. Is the subsequent control for data transmission and storage primarily handled by ddr2_ip_example_driver (without modifying ddr2_ip_inst)?

Do I need to pay for the use of this IP? " No. The Quartus II Web Edition no longer require a license file. " Q2: Can the purpose of creating this IP be understood as the communication interface between FPGA and external DDR2? " Yes " Q3 : The following picture shows the instantiated DDR2 IP. Is the subsequent control for data transmission and storage primarily handled by ddr2_ip_example_driver (without modifying ddr2_ip_inst)? " Yes. It's an example design that generated to test the IP.
