2.4. Control and Status Interface
Port Name | Width (in bits) | I/O Direction | Description |
---|---|---|---|
o_dr_curr_profile_id | 15 | Output | Specifies the selected profile. The signal is only valid when o_dr_new_cfg_applied is 1. You must decode the values to decide if the design is dynamically reconfigured. |
o_dr_new_cfg_applied | 1 | Output | Specifies the new configuration settings to the external logic, including tile CSRs, mux selection, etc. Once the signal is sampled active, the external logic returns an acknowledgment to complete a full handshake signaling. Since this is a hardware action, the signal must complete within nanosecond ranges. Once this signal is active, the Nios® continues to monitor the acknowledgment before proceeding to the next process in the dynamic reconfiguration flow. After an acknowledgment is sampled, this signal becomes inactive and the Nios® proceeds to the next step. If an acknowledgment is not sampled at a prolong period of time and time-out is enabled, this signal also becomes inactive and the Nios® proceeds to the next step at time-out. A time-out error also is signaled in this case. |
i_dr_new_cfg_applied_ack | 1 | Input | Specifies the full handshake acknowledgment in response to o_dr_new_cfg_applied signal. The signal is active when set to 1. |
o_dr_in_progress | 1 | Output | Specifies that the dynamic reconfiguration is in progress. This signal is active when set to 1. |
o_dr_error_status | 1 | Output | Specifies the overall dynamic reconfiguration SIP error status, including dynamically reconfigured Nios® firmware errors. This signal is active when set to 1. |
o_dr_fast_sim_clk_sel | 1 | Output | Used during simulation only. When used, allows you to reduce the simulation run time by driving the i_cpu_clk port with different input frequencies.
