Statistically, one error out of 2048 might go undetected.
Conguration Sequence
There are four major steps in the XC4000 Series power-up
conguration sequence.

Start-Up
The full process is illustrated in Figure 46.
Conguration Memory Clear
When power is rst applied or is reapplied to an FPGA, an
internal circuit forces initialization of the conguration logic.
When Vcc reaches an operational level, and the circuit
passes the write and read test of a sample pair of congu-
ration bits, a time delay is started. This time delay is nomi-
nally 16 ms, and up to 10% longer in the low-voltage
devices. The delay is four times as long when in Master
Modes (M0 Low), to allow ample time for all slaves to reach
a stable Vcc. When all INIT pins are tied together, as rec-
ommended, the longest delay takes precedence. There-
fore, devices with different time delays can easily be mixed
and matched in a daisy chain.
This delay is applied only on power-up. It is not applied
when re-conguring an FPGA by pulsing the PROGRAM
