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 one parallel clock cycle for
correct simulation behavior.
You can de-assert 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 de-asserted 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.
