Dynamic Reconfiguration Reset Sequences
The gxb_powerdown port is optional. In simulation, if the gxb_powerdown port
is not instantiated, you must assert the tx_digitalreset, rx_digitalreset,
and rx_analogreset signals appropriately for correct simulation behavior.
If the gxb_powerdown port is instantiated, and the other reset signals are not
used, you must assert the gxb_powerdown signal for at least 1 s for correct
simulation behavior.
You can deassert the rx_digitalreset signal immediately after the
rx_freqlocked signal goes high to reduce the simulation run time. It is not
necessary to wait for t
The busy signal is deasserted after about 20 parallel reconfig_clk clock cycles
in order to reduce simulation run time. For silicon behavior in hardware, you can
follow the reset sequences described in the previous pages.
In PCIe mode simulation, you must assert the tx_forceelecidle signal for at
least one parallel clock cycle before transmitting normal data for correct
simulation behavior.
