Important information
This document applies exclusively to the configuration of the NG-LARGE FPGA referenced NX1H140TSP.
For other NanoXplore chips, please refer to the associated documentation.
Introduction to NG-LARGE Configuration
NX1H140TSP is configured by loading the bitstream into internal configuration memory using one of these following modes:
JTAG,
Slave Parallel 8 bits,
Slave Parallel 16 bits,
Slave SpaceWire, compliant ECSS-E-ST-50-12C link,
Master SPI, compliant with SPI JESD68.01
WARNING: changing MODE value while RST_HARD_N is unasserted is strictly forbidden.
Bitstream size
This NX1H140TSP bitstream size depends on the amount of logic resources used by the application, the number of initialized Flip-flops and the number of user Core RAM and Core Register Files to be initialized.
Maximum user logic configuration (100%) | 24.43Mb |
Medium configuration (70%) | 17.10Mb |
Small configuration (50%) | 12.22Mb |
D-Flip-Flop initialization (1) (129024) | 1b/D-Flip-Flop |
Core RAM initialization (2) (192 instances) | 96.06Kb/RAM block |
Core Register File initialization (2) (672 instances) | 3.03Kb/Register File |
CMIC | 64.15Kb |
Total | 44.53Mb |
In a typical design the user can give – or not - an initial value to Flip-Flops at power-up. Reducing the number of initialized Flip-Flops contributes to reduce the bitstream size.
Core RAM and/or Core Register file can also be initialized – or not - at power-up. Reducing the number of initialized memories contributes to reduce the bitstream size.
Most applications do not require to initialize all memories.
These numbers are just estimations.
The actual size can be determined only by running the mapping software.
Configuration Memory Integrity Check (CMIC)
The CMIC is an embedded engine performing automatic verification and repair of the configuration memory.
A CMIC reference memory is initialized during the bitstream download process with reference data computed by the NanoXmap software.
Once the initialization is done, the CMIC engine can be periodically activated to perform the following sequence:
1. Read configuration data
2. Calculate signature
3. Compare the signature with CMIC reference
4. If a mismatch is detected:
a. Calculate faulty address (BAD @) and faulty bit location
b. Read DATA[BAD @]
c. Repair flipped bit
d. Write DATA[BAD @]
For further information, please refer to the NX1H140TSP CMIC Application note.
Device configuration details
Purpose of NX1H140TSP configuration
NX1H140TSP chips are SRAM-based FPGAs. To achieve user-defined functionality their configuration bitstream must be downloaded first.
NX1H140TSP chips configuration modes summary
NX1H140TSP chips are always accessible through JTAG, and also support several configuration modes.
At power-up, MODE [2:0] pins state defines the configuration mode.
RST_HARD_N is a dedicated input pin that allows to reset the configuration engine, and launches the configuration process after RST_HARD_N is released. (It can’t be used to reset the FPGA user’s logic).
MODE [2:0] | Configuration mode |
---|---|
000 0x0 | Master Serial SPI |
001 0x1 | Master Serial SPI with VCC control |
010 0x2 | Slave Spacewire |
011 0x3 | JTAG (reserved) |
100 0x4 | Slave Parallel 8-bit |
101 0x5 | Slave Parallel 16-bit |
110 0x6 | Reserved |
111 0x7 | Test mode |
Table: NG-LARGE NX1H140TSP configuration modes
Configuration modes usage
JTAG configuration channel is always active regardless the selected configuration mode. JTAG accesses while the configuration interface is active are not recommended (risk of conflict with the bitstream manager operation and render ineffective the bitstream manager)
In slave modes (SpaceWire, Slave Parallel 8 or Slave Parallel 16), NX1H140TSP chip must be fed its bitstream through the selected interface.
In Master Serial SPI modes, NX1H140TSP chip automatically fetches its bitstream from the external memory (SPI or SPI with Vcc control) after RST_HARD_N is released.
Prog bank pins state during and after configuration
According the selected configuration mode, each of the prog is “multi-usage”. Some of the active pins must be required for correct configuration, and some other pins must be left unconnected. In addition, some prog bank pins can be configured as additional user’s I/O, providing that the supported I/O standard is:
LVDS with external impedance adaptation for the dedicated SpaceWire pins.
LVCMOS_3.3V for the other prog pins (with 60 mA output drive for the outputs, and 10K to 40K default Pull-Up)
The prog bank pins that are not used or activated by the selected configuration mode are configured as High-Z during the configuration. After the configuration they stay configured as High-Z if not used, or take the user’s defined functionality.
JTAG input pins (TRST, TMS, TDI) get internal default Pull-Up (10K to 40K).
User’s I/O pins state during and after configuration
Before reset, I/Os state are undetermined.
During the configuration process, all user’s I/Os are configured as High-Z with an internal 10K to 40K default Pull-Up.
After configuration the user I/O pins behaves as defined by the bitstream.
Internal default Pull-Up is set on single ended inputs.
NX1H140TSP chips prog interface pin list
The user must provide the 3-bit MODE value to select the configuration mode. In addition, the internal configuration engine requires an external reset signal (RST_HARD_N). RST_HARD_N must be asserted (low) during at least 3 microseconds. When RST_HARD_N is de-asserted, the configuration process starts after up to 3 us delay, according the MODE bits settings.
WARNING: changing MODE value while RST_HARD_N is unasserted is strictly forbidden (undefined behavior).
Depending on the selected configuration MODE, some prog bank pins are activated during the process. Some other remain as inputs with internal Pull-Up during the configuration process.
In addition, some prog bank pins can be used as auxiliary user defined I/Os after completing the configuration.
The next table summarizes the list of pins that can be affected during the configuration process.

Detailed configuration modes
SPI Modes
On board SPI flash memory programming:
For Master Serial modes, the on-board flash memory programming operation requires changing the MODE[2:0] into Slave mode to ensure the accessibility to the flash.
The NX1H140TSP chip may then be configured through JTAG with a dedicated design to program the memory with the user data, also transmitted by JTAG. NxBase2 provides such design and commands to program a given list of SPI flash memories. Please refer to NanoXplore_NxBase2_User_Manual.
Endianness
The bitstream must be sent by 32bits words with less significant byte first. Each byte must be sent with most significant bit first.
As an example, 0x12345678 is the first word of each bitstream. It must be sent as follows:
Bistream manager clock
In Master SPI or in Master SPI + Vcc control, only an external clock can be used to connect to CLK IO.
Do not loop CLK_OSC to CLK in these modes.

The next figure shows a suggestion of schematic to implement the Master Serial SPI with VCC control configuration, then the pin list table describes the behavior of the prog bank pins when this mode is selected.
This configuration mode is the same as Master Slave SPI, with the only difference that the SPI Flash memory is powered by using 3 pins of the NG-LARGE prog bank to supply the external SPI. This can contribute to reduce the risk of corruption of bitstream/data stored into the external SPI memory device.

Spacewire configuration instructions
The supported SPW instructions by the NG-LARGE FPGA are as stated in the table below.
Command Code | Command |
0x01 | ADDR_DEBUG |
0x02 | READ_DEBUG |
0x04 | WRITE_DEBUG |
0x08 | WRITE_CONF |
Table: NG-LARGE SPW instructions
ADDR_DEBUG instruction
The ADDR_DEBUG instruction is used to set the address of the loader register which will be accessed in all subsequent instructions. Following figure illustrates the format of the packet. Note that if many reads and writes will be performed to the same register only one ADDR_DEBUG instruction is needed.
READ_DEBUG instruction
The READ_DEBUG instruction is used to read the loader register value from the address defined by the previous ADDR_DEBUG instruction. READ_DEBUG instruction is a 1-byte packet containing only the instruction code (0x02) as shown in 5 below. The FPGA responds with a 4-bytes packet containing the read value which is sent LSB first as shown in 6.
WRITE_DEBUG instruction
The WRITE_DEBUG instruction is used to write a value to the address of the loader register defined by the previous ADDR_DEBUG instruction. WRITE_DEBUG instruction contains the instructions code (0x04) followed by 4-bytes data to be written. Data is sent LSB first as shown in the following figure:
WRITE_CONF instruction
The WRITE_CONF instruction is used to program the NG-LARGE FPGA.
The SPW packet size depends on bitstream size and it has the following fields:
Instruction code: 0x08 for WRITE_CONF
FPGA bitstream: the bitstream to be programmed into the FPGA.
This field is obtained by converting each 32bits bitstream word to 4 bytes sent LSB first as illustrated in the figure below:

Table: Slave Parallel 8 – Slave Parallel 16 configuration pins description
Slave Parallel interface usage
In Slave Parallel 8 and Slave Parallel 16 modes, the configuration clock must be provided to the FPGA on the dedicated CLK input pin. Its frequency can range in [0MHz;100MHz], in any case it must be strictly greater than twice the JTAG (TCK) frequency – if used.
In order to avoid setup/hold time problems, the master can use the falling CLK edge to generate CS, TYPE[1:0] and D(7:0) or D(15:0).
The master can start downloading the bitstream bytes after 50 configuration clock (CLK) cycles.
Each data access is done on the rising edge of CLK, while CS is activated (high level) and TYPE[1:0] informing type of access. Dummy cycles can be inserted – if required by the master by de-asserting CS during one or more cycles between two data. The next figure illustrates an example of timing diagram.
Data are 32 bits long and are sent in the following order:
In Slave Parallel 16 mode, DATA[15:0] and then DATA[31:16].
In Slave Parallel 8 mode, DATA[7:0], then DATA[16:8], then DATA[23:16] and then DATA[31:24].
Internal interface between fabric and BSM
I/O direction is given for fabric side.
Global signals
The following signals can be used by the fabric and consequently get an impact in the design if needed by users:
Grp | Name | I/O | Description |
---|---|---|---|
GLOBAL | CLK_BSM | I | Always required. Can be routed externally to CLK_OSC 100MHz internal oscillator or to an external clock in the range [0MHz;100MHz]. |
COLD_START | I | Goes high if the FPGA is ready and not reboot because of error occurred. | |
READY | I | Goes high when the configuration is complete (the FPGA enters in user’s mode) | |
TRIGGER | I | 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 | I | 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. |
Slave Parallel 8 interface
There is an internal interface between the Bitstream Manager and the fabric. It operates as slave parallel 8 interface.
The difference is Bitstream Manager registers write/read accesses are made from the fabric and give the ability to use these control and status registers in the design.
Grp | Name | I/O | Description |
---|---|---|---|
Parallel User | CS | O | Description is the same than Slave Parallel 8 except that for this interface, commands are sent from the fabric. DVAL is equivalent to DATA_OE. |

Boundary scan
IEEE 1149 JTAG implementation
NX1H140TSP devices support IEEE Std 1149.1 JTAG boundary scan operation for board and device testing.
The EXTEST, INTEST, SAMPLE, BYPASS, IDCODE, USERCODE, and HIGHZ instructions are all included. The tap also supports internal user-defined registers (USER1, USER2) and instructions for device configuration and test.
JTAG interface pins include the standard TCK, TMS, TDI and TDO pads, as well as the optional TRST pad.
NX1H140TSP chips JTAG instructions
NX1H140TSP chips boundary scan instructions are the following:
Hex | Instruction | Function |
---|---|---|
0x0 | EXTEST | Boundary scan external test |
0x1 | SAMPLE | Boundary scan sample |
0x1 | PRELOAD | Boundary scan preload |
0x2 | WR_CONF | Nanoxplore bitstream download |
0x3 | WR_DEBUG | Write debug instruction |
0x4 | RD_DEBUG | Read debug instruction |
0x5 | ADDR_DEBUG | Address debug instruction |
0x6 | INTEST | Boundary scan in internal test |
0x7 | IDCODE | Boundary scan design identification |
0x8 | USRCODE | User design identification register |
0x9 | USER1 | User registers access |
0xA | USER2 | User registers access |
0xC | HIGHZ | Tri-state all device I/Os |
0xF | BYPASS | Single-clock bypass TDI to TDO |
Table: Boundary scan instructions
NX1H140TSP devices provide a 1046-bit scan chain, described in each device BSDL file.
The WRITE_CONF instruction is used to program the NG-LARGE FPGA.
The ADDR_DEBUG instruction is used to set the address of the loader register which will be accessed in all subsequent instructions.
The READ_DEBUG instruction is used to read the loader register value from the address defined by the previous ADDR_DEBUG instruction.
The WRITE_DEBUG instruction is used to write a value to the address of the loader register defined by the previous ADDR_DEBUG instruction.
The IDCODE instruction returns the NG-LARGE Identification’s code: 0x675.
The USRCODE instruction returns the user-defined code (0xFFFFFFFF by default).
The USER1 instruction is used to access to the user1 registers from the FPGA fabric.
The USER2 instruction is used to access to the user2 registers from the FPGA fabric.
The HIGHZ instruction is used to deactivate the outputs of all pins.
The BYPASS instruction is used to bypass the device.
Endianness
The JTAG commands must be sent by 32bits words with less significant bit first.
Hereafter an example of bitstream loading using WR_CONF command. The first word 0x12345678 is sent with the following sequence “0001 1110 0110 … 0100 1000”
In order to write or read a Bitstream Manager register, it needs a ADDR_DEBUG command followed by respectively a WR_DEBUG or RD_DEBUG command. The address is 32 bits long and data are 96 bits long.
NX1H140TSP boundary scan usage
NX1H140TSP chips are fully programmable devices, so boundary scan instructions usage requires some minimal device configuration using a limited bitstream, especially for the EXTEST instruction:
- pads to be used as outputs need a minimum output drive configuration.
- pads to be used as inputs need a minimum input thresholds configuration.
NX1H140TSP boundary scan errata
NX1H140TSP chips boundary-scan architecture presents some implementation bugs, listed below:
Chip initialization with unused JTAG interface
Problem:
When JTAG interface is not used, the NX1H140TSP chip initialization may fail on a boundary scan initialization error. The interface initialization requires at least one rising edge on the TCK JTAG clock.
Workaround:
- unused JTAG input pads TCK, TMS and TDI should be provided a 10-100KΩ pull-up resistor to VDDIO_SERVICE.
- unused TRST input should be provided a 1KΩ pull-down resistor
- TCK should be driven by a diode (anode) connected to RST_HARD_N (cathod) prog interface reset pin, so that the end-of-reset rising edge provides the required TCK.
Dedicated clock inputs in boundary scan INTEST
Problem:
In boundary scan INTEST instruction execution, the dedicated clock inputs on the SIMPLE banks (0, 1, 6 and 8) are seen by the internal design as simple inputs but not as clock inputs.
Dedicated clock inputs on the COMPLEX banks (2, 5, 9 and 12) are fully functional in boundary scan INTEST.
NG_LARGE register
To access a register, the user needs to use the ADDR_DEBUG instruction first, and then the WR_DEBUG or RD_DEBUG instructions.
Note all NG-MEDIUM registers are kept in NG-LARGE and get the same addresses.
