2.3.2.3. Input Path Signals

Table 18.  Input Path SignalsInput path signals are signals that are available when you set Pin Type to Input or Bidirectional. The <n> in the signal names in the following table represent 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-rateSDR: 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 group_<n>_rdata_valid. Synchronous to the core_clk_out output from the IP.
group_rdata_en Input

Quarter-rate: 4

Half-rate: 2

Full-rate: 1

Read enable signal.

This signal is set to high after a read command is issued. Synchronous to the core_clk_out output from the IP.

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

Each group has separate read enable.
group_<n>_rdata_valid Output

Quarter-rate: 4

Half-rate: 2

Full-rate: 1

Read valid signal

This signal determines which data are valid when reading from RX FIFO.

Synchronous to the core_clk_out output from the IP.

group_<n>_data_in/

group_<n>_data_io

Input/ Bidirectional 1 to 22

Input data from 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 group_<n>_strobe_in/ group_<n>_strobe_io.

If the pin type is set to Input, the group_<n>_data_in ports are used. If the pin type is set to Bidirectional, the group_<n>_data_io ports are used.

group_<n>_data_in_n/

group_<n>_data_io_n

Input/ Bidirectional 1 to 22

Differential input data from external device. Synchronous to the group_<n>_strobe_in_n or group_<n>_strobe_io_n output from the IP,

group_<n>_strobe

_in/ group_<n>_strobe

_io

Input/ Bidirectional 1 Input strobe from 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 Bidirectional, the group_<n>_strobe_io signal is used.

group_<n>_strobe

_in_n/ group_<n>_strobe

_io_n

Input/ Bidirectional 1

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