2.3.2.2. Output Path Signals
The following table provides the output path signals in PHY Lite for Parallel Interfaces FPGA IP for Agilex™ 5 D-Series and E-Series devices.
Signal Name | Direction | Width | Description |
---|---|---|---|
group_<n>_data_from_core | Input | 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 |
Data signal from the FPGA core. Synchronous to the core_clk_out output from the IP. |
group_<n>_oe_from_core | Input | Quarter rate: 4 Half rate: 2 Full rate: 1 |
Output enable signal from the FPGA core. Synchronous to the core_clk_out output from the IP. Each group has separate output enable. |
group_<n>_strobe_out_en | Input | Quarter rate: 4 Half rate: 2 Full rate: 1 |
Strobe output enable from the FPGA core. Synchronous to the core_clk_out output from the IP. Each group has separate strobe enable. |
group_<n>_strobe_from_core | Input | Quarter rate: 8 Half rate: 4 Full rate: 2 |
Strobe pattern from core. Simple strobe pattern can be generated by this signal with 8’h55 values. |
group_<n>_data_out / group_<n>_data_io | Output | 1 to 22 | Data output from the IP. Synchronous to the group_<n>_strobe_out or group_<n>_strobe_io output from the IP. If the Pin Type is set to Output, the group_<n>_data_out signals are used. If the Pin Type is set to Bidirectional, the group_<n>_data_io signals are used. |
group_<n>_data_out_n / group_<n>_data_io_n | Output | 1 to 22 | Differential data output from the IP. Synchronous to the group_<n>_strobe_out_n or group_<n>_strobe_io_n output from the IP. |
group_<n>_strobe_out/ group_<n>_strobe_io | Output | 1 | Positive output strobe from the IP. If the Pin Type is set to Output, the group_<n>_strobe_out signal is used. If the Pin Type is set to Bidirectional, the group_<n>_strobe_io signal is used. |
group_<n>_strobe_out_n / group_<n>_strobe_io_n | Output | 1 | Negative output strobe from the IP. This is used if the Strobe Configuration is set to Differential. If the Pin Type is set to Output, the group_<n>_strobe_out_n signal is used. If the Pin Type is set to Bidirectional, the group_<n>_strobe_io_n signal is used. |
