2.7. Agilex™ 7 Configuration Time Estimation
The table provides time estimates for the full FPGA configuration only. In HPS enabled designs, the table also considers the FPGA configuration first mode. Note that the HPS boot first mode in HPS enabled designs is not considered. Also, the CvP periphery image configuration is not considered.
In AVST mode, to optimize configuration time during the initial configuration after power-on reset (POR) and during reconfiguration, the external host should be prepared to send data to the device before driving nCONFIG high. Once nCONFIG and nSTATUS are high, the host may begin transmitting data as soon as the device asserts the AVST_READY signal when it is ready to receive data. This ensures that there is minimal delay from the device waiting for the host to start sending data after AVST_READY is asserted. Following this procedure does not affect the configuration process.
The Mailbox command GET_CONFIGURATION_TIME provides a time estimate for processing the configuration bitstream, beginning with loading of the SDM firmware until the entire design section of the configuration bitstream is configured and the device enters user mode. For more information, refer to the Configuration File Format Differences section.
Intel recommends measuring the configuration time starting from when nSTATUS goes high to when CONF_DONE goes high. For more information, refer to the Power-On, Configuration, and Reconfiguration Timing Diagram section.
- Set the VID mode of operation to PMBus Master mode
- Use Intersil ISL68137 regulator to regulate the PMBus
- Set configuration clock source to OSC_CLK_1 with 25/100/125 MHz
- No advanced security features were enabled
- For AVST x8/x16/x32 configuration modes, set the AVST_CLK to 125 MHz. The external host controller supplies the AVST_DATA by asserting the AVST_VALID signal high whenever the AVST_READY signal is high.
- For AS x4 configuration mode, set the AS_CLK to 166 MHz. Use a Micron device with a 2 Gb density range QSPI flash memory.
- Configuration time is measured starting from when nSTATUS goes high to CONF_DONE goes high.
