MODE(2:0)

I

Input pins sampled at power-up. MODE(2:0). They define the 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

Device Identification. It must comply with the bitstream device id to allow access bitstream loading.

FABRIC_USER(3:0)

I

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

CLK

I

Always required. Can be routed externally to CLK_OSC 100MHz internal oscillator (except in Master SPI modes) or to an external clock in the range [0MHz;100MHz].

RST_HARD_N

I

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

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

READY

O

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

TRIGGER

O

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

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.

POK

O

Goes high when VDD1V2 Core and VDD2VA VDD2V5A Analog Supply are on.

Slave Parallel 16/8

CS

I

Active high Chip Select input. Used in Slave Parallel 16/8 mode. The master can write or read to/from the configuration engine when CS is high during a CLK rising edge.

TYPE[1:0]

I

2-bits control input. Used in Slave Parallel 16/8 mode. It indicates the type of access:

0b00: ADDR_DEBUG

0b01: READ_DEBUG

0b10: WRITE_DEBUG

0b11: WRITE_CONF

DATA_OE

O

Active high output. Used in Slave Parallel 16/8 mode. It is a data valid signal for reading operations.

D(15 :0)

I/O

16-bit data bus used in Slave Parallel 16/8 mode to write the bitstream and/or read internal NG-LARGE internal state values. In case of Slave Parallel 8, only the first 8 LSB are used.

Master Serial SPI

D(8)

O

Used in Master Serial SPI and Master Serial SPI with Vcc control, as CS output to the external SPI Flash memory.

D(9)

O

Used in Master Serial SPI and Master Serial SPI with Vcc control, as clock output to the external SPI Flash memory.

D(10)

I

Used in Master Serial SPI and Master Serial SPI with Vcc control, as data input (MISO) from the external SPI Flash memory.

D(11)

O

Used in Master Serial SPI and Master Serial SPI with Vcc control, as data output (MOSI) to the external SPI Flash memory (while writing a new bitstream into the SPI Flash.

D(12)

I
