Figure 10–5. FPP Configuration Timing Waveform with Decompression or Design Security Feature Enabled
Notes to
(1) Use this timing waveform when you have enabled the decompression and/or design security features.
(2) The beginning of this waveform shows the device in user-mode. In user-mode, nCONFIG, nSTATUS, and CONF_DONE are at logic high levels.
(3) After power-up, the Stratix IV device holds nSTATUS low for the time of the POR delay.
(4) After power-up, before and during configuration, CONF_DONE is low.
(5) Do not leave DCLK floating after configuration. You can drive it high or low, whichever is more convenient.
(6) DATA[7..0] are available as user I/O pins after configuration except for some exceptions on Stratix IV GT devices. The state of these pins
(7) If needed, you can pause DCLK by holding it low. When DCLK restarts, the external host must provide data on the DATA[7..0] pins prior to
