3.5.1. Guidelines: Group Pin Placement
Follow these guidelines to place the PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP group pins.
- All groups in a PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP must be placed across a contiguous set of lanes. The number of lanes depends on the number of pins used by the group.
- Two groups, from either the same or different PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP, cannot share an I/O lane.
- For PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP instance that spans more than one I/O bank, all groups in the interface must be placed across a contiguous set of banks within an I/O column. The number of I/O banks required depends on the memory interface width.
- Pins that are not used in an I/O bank are available as general purpose I/O (GPIO) pins.
- To constrain groups from separate PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP instances into the same I/O bank, the instances must share the same reference clock and reset sources, the same external memory frequencies, and the same voltage settings.
- A reference clock network can only span across maximum of 6 I/O banks.
- You cannot share the OCT termination block across the I/O column. You can associate the terminated pins of the PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP instance with an RZQ pin through RZQ_GROUP assignment.
Number of Pins in Group | Valid DQS Group in a Bank | Valid Index in a Bank |
---|---|---|
1-12 | DQS for X8/X9 | {0-11}/{12-23}/{24-35}/{36-47} |
13-24 | DQS for X16/X18 | {0-23}/{24-47} |
25-48 | DQS for X32/X36 | {0-47} |
