The reset_n pin does not require PHASER_CONTROL, OUT_FIFO, PHASER_OUT, and PHASER_REF. Therefore, the following must be performed to work around the problem:
If reset_n is allocated a bank below Data and Address/Control byte groups:
If reset_n is allocated a bank above Data and Address/Control byte groups:
This problem does not affect single controller designs as these constraintsare automatically trimmed away by the ISE software.This issue is scheduled to be fixed in the 13.3 software release and further documentation on the pin-out parameters is to be provided.
