5.3.2.3. Input Path Signals

Table 100.  Input Path SignalsInput path signals are signals that are available when you set the Pin Type parameter to Input or Bidirectional. The <n> in the signal names below represents the group number in the IP.
Signal Name Direction Width Description
group_<n>_data_to_core Output

Quarter-rate DDR: 8 x PIN_WIDTH

Half-rate DDR: 4 x PIN_WIDTH

Full-rate DDR: 2 x PIN_WIDTH

Quarter-rate SDR: 4 x PIN_WIDTH

Half-rate SDR: 2 x PIN_WIDTH

Full-rate SDR: 1 x PIN_WIDTH

Output data to the core logic. Valid on rdata_valid. Synchronous to the core_clk output from the PHY Lite for Parallel Interfaces Intel® FPGA IP for Stratix® 10 devices.
group_<n>_rdata_en Input

Quarter-rate: 4

Half-rate: 2

Full-rate: 1

 This signal represents the number of expected words to read from the external device.

This signal is set to high after a read command is issued. Synchronous to the core_clk output from the PHY Lite for Parallel Interfaces Intel® FPGA IP for Stratix® 10 devices.

When using the IP as a receiver, assert this signal after interface_locked signal is asserted and strobe_in is stable.

group_<n>_rdata_valid Output

Quarter-rate: 4

Half-rate: 2

Full-rate: 1

 This signal determines which data are valid when reading from Read FIFO. Delayed by READ_LATENCY with margin and aligned to the core clock rate. For example, in quarter-rate, the delay is a multiple of 4 external clock cycles.

Synchronous to the core_clk output from the PHY Lite for Parallel Interfaces Intel® FPGA IP for Stratix® 10 devices.

group_<n>_data_in/

group_<n>_data_io

Input/Bidirectional 1 to 48 if data configuration is Single Ended Input and output data from/to external device. Synchronous to the group_<n>_strobe_in or group_<n>_strobe_io input. The first data_in must be associated with positive edge of strobe_in/strobe_io.

If the pin type is set to Input, the data_in ports are used. If the pin type is set to bidirectional, the data_io ports are used.

Note: PHY Lite for Parallel Interfaces Intel® FPGA IP for Stratix® 10 devices does not support differential data pins.
group_<n>_strobe_in/group_<n>_strobe_io Input/Bidirectional 1

Input and output strobe from/to external device. If the pin type is set to Input, the group_<n>_strobe_in signal is used. If the pin type is set to Bidirection, the group_<n>_strobe_io signal is used.

group_<n>_strobe_in_n group_<n>_strobe_io_n Input/Bidirectional 1 Negative strobe from/to external device. This is used if the Strobe Configuration parameter is set to Differential or Complementary. If the pin type is set to Input, the strobe_in_n signal is used. If the pin type is set to Bidirectional, the strobe_io_n signal is used.
