3.3.2.3. Input Path Signals
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. |
