Pin behavior

GLOBAL

MODE(2:0)

I

No

Yes

000

Input pins sampled at power-up. MODE(2:0). They define the configuration mode to be used for NG-LARGE configuration.

MODE(2:0) cannot be changed when RST_HARD_N = ‘1’

ID(3:0)

I

No

Yes

-

Device Identification. It must comply with the bitstream device id to allow access bitstream loading or the bitstream device id e equal to 0xF (broadcast mode).

FABRIC_USER(3:0)

I

Yes

No

-

Additional IO for user. FABRIC_USER[0] can be connected to low-skew network.

CLK

I

No

Yes

-

Always required. Must be routed to an external clock in the range [0MHz;100MHz].

RST_HARD_N

I

No

Yes

-

Mandatory input. When low, it resets the internal configuration engine. RST_HARD_N must be low at least during 3 microseconds to ensure a proper configuration engine reset. When RST_HARD_N goes high, the configuration starts after up to 3 additional microseconds.

RST_SOFT_N

I

No

No

-

It only resets internal configuration registers but does not apply a reset on the configuration memory.

READY

O

No

No

Yes

Goes high when the configuration is complete (the FPGA enters in user’s mode)

TRIGGER

O

No

No

Yes

Generates a high-level pulse (~20 ns or one CLK cycle) each time an error is encountered during the configuration and during design processing. Error is taken into account only if it is not masked by the associated TRIGGER_MASK.

ERROR

O

No

No

Yes

Generates a high-level pulse (~20 ns or one CLK cycle) each time an error is encountered during the configuration and during design processing. Error is taken into account only if it is not masked by the associated ERROR_MASK.

No

No

No

Goes high when VDD1V2 Core and VDD2V5A Analog Supply are on.
