184.108.40.206. Estimating Pin Requirements
- Determine how many read/write data pins are associated per data strobe or clock pair.
- Calculate the number of other memory interface pins needed, including any other clocks (write clock or memory system clock), address, command, and RZQ. Refer to the External Memory Interface Pin Table to determine necessary Address/Command/Clock pins based on your desired configuration.
- Calculate the total number of I/O banks required to implement the memory interface, given that an I/O bank supports up to 96 pins.
You should test the proposed pin-outs with the rest of your design in the Intel® Quartus® Prime software (with the correct I/O standard and OCT connections) before finalizing the pin-outs. There can be interactions between modules that are illegal in the Intel® Quartus® Prime software that you might not know about unless you compile the design and use the Intel® Quartus® Prime Pin Planner.
