Intel Stratix 10 Configuration User Guide

Idle
• The SDM remains in IDLE state until the external host initiates configuration by
driving the nCONFIG pin from low to high, alternatively, the SDM enters the idle
state after it exits the error state.
•
The SDM reads the nCONFIG pin status.
•
If the nCONFIG pin is high and a configuration error occurs, the SDM drives
nSTATUS pin low for 1 ms ±50%. After which nSTATUS remains high until an
external source drives the nCONFIG pin low. After nCONFIG is driven low, the SDM
drives nSTATUS low. The SDM is now in the idle state.
Configuration Start
• The SDM receives configuration data from the source configuration bitstream and
performs authentication, decryption and decompression.
• The SDM configures the FPGA fabric.
•
Configuration begins when the nSTATUS pin is high.
•
The nCONFIG pin remains high during configuration and in user mode.
Configuration Pass
• The SDM enters the Pass state after it completes device configuration.
•
The Intel Stratix 10 device drives the CONF_DONE or INIT_DONE pin high after
successful configuration completes.
• The device is not in user mode.
Configuration Error
•
A low put on the nSTATUS pin LOW for 1ms ± 50% indicates a configuration error.
•
After low pulse indicating an error, the SDM drives the nSTATUS pin high if the
nCONFIG pin remains high. These unique pin conditions indicate a configuration
error.
•
After an error the SDM enters Idle state if nCONFIG is low until the external host
drives the nCONFIG pin high.
User Mode
•
The SDM drives the INIT_DONE pin high after initializing internal registers and
releases GPIO pins from the high impedance state. The device enters user mode.
The entire device does not enter user mode at the same instant.
•
The nCONFIG pin should remain high in user mode. To initiate reconfiguration, the
external host drives nCONFIG low. Then, a rising edge on nCONFIG initiates
reconfiguration.
Device Clean
• Device cleaning zeros out all configuration data.
• The design stops functioning.
•
The Intel Stratix 10 device drives CONF_DONE and INIT_DONE low.
The nSTATUS pin goes low when device cleaning completes.
