+# Corundum for NT200A01/NT200A02
+
+## Introduction
+
+This design targets the Napatech NT200A01/NT200A02 FPGA board.
+
+*  QSFP28
+    *  10GBASE-R or 25GBASE-R MACs via GTY transceivers
+
+## Board details
+
+* FPGA
+  * NT200A01: xcvu095-ffva2104-2-e
+  * NT200A02: xcvu5p-flva2104-2-e
+*  PCIe: gen 3 x16 (~128 Gbps)
+*  Reference oscillator: 322.265625 MHz from Si5340
+*  25GBASE-R PHY: Soft PCS with GTY transceivers
+
+## Licensing
+
+*  Toolchain
+    *  Vivado Enterprise (requires license)
+*  IP
+    *  No licensed vendor IP or 3rd party IP
+
+## How to build
+
+Run `make` in the appropriate `fpga*` subdirectory to build the bitstream.  Ensure that the Xilinx Vivado toolchain components are in PATH.
+
+On the host system, run `make` in `modules/cndm` to build the driver.  Ensure that the headers for the running kernel are installed, otherwise the driver cannot be compiled.
+
+## How to test
+
+Run `make program` to program the board with Vivado.  Then, reboot the machine to re-enumerate the PCIe bus.  Finally, load the driver on the host system with `insmod cndm.ko`.  Check `dmesg` for output from driver initialization.  Run `cndm_ddcmd.sh =p` to enable all debug messages.
+
+## JTAG pinout
+
+Napatech boards use a non-standard connector for JTAG.  There are three debug connectors, and one of them carries the JTAG signals for the FPGA.
+
+        J16             J22
+        FPGA            AVR
+    TDI 7 8 GND     TDI 7 8 GND
+    TMS 5 6 HALT    TMS 5 6
+    TDO 3 4 Vref    TDO 3 4 Vref
+    TCK 1 2 GND     TCK 1 2 GND
+
+            J17
+        GND 2 1
+            4 3
+            6 5
+
+Note: J18.6 HALT must be driven low to access the JTAG chain.  So, either tie to to ground, or connect it to the HALT signal on DLC9/DLC10 cables.

+Generic module for I2C bus initialization.  Good for use when multiple devices
+on an I2C bus must be initialized on system start without intervention of a
+general-purpose processor.
+
+Copy this file and change init_data and INIT_DATA_LEN as needed.
+
+This module can be used in two modes: simple device initialization, or multiple
+device initialization.  In multiple device mode, the same initialization sequence
+can be performed on multiple different device addresses.
+
+To use single device mode, only use the start write to address and write data commands.
+The module will generate the I2C commands in sequential order.  Terminate the list
+with a 0 entry.
+
+To use the multiple device mode, use the start data and start address block commands
+to set up lists of initialization data and device addresses.  The module enters
+multiple device mode upon seeing a start data block command.  The module stores the
+offset of the start of the data block and then skips ahead until it reaches a start
+address block command.  The module will store the offset to the address block and
+read the first address in the block.  Then it will jump back to the data block
+and execute it, substituting the stored address for each current address write
+command.  Upon reaching the start address block command, the module will read out the
+next address and start again at the top of the data block.  If the module encounters
+a start data block command while looking for an address, then it will store a new data
+offset and then look for a start address block command.  Terminate the list with a 0
+entry.  Normal address commands will operate normally inside a data block.
+
+Commands:
+
+00 0000000 : stop
+00 0000001 : exit multiple device mode
+00 0000011 : start write to current address
+00 0001000 : start address block
+00 0001001 : start data block
+00 001dddd : delay 2**(16+d) cycles
+00 1000001 : send I2C stop
+01 aaaaaaa : start write to address
+1 dddddddd : write 8-bit data
+

+# Taxi Example Design for NT200A01/NT200A02
+
+## Introduction
+
+This example design targets the Napatech NT200A01/NT200A02 FPGA board.
+
+The design places looped-back MACs on the QSFP28 ports.
+
+* QSFP28
+  * Looped-back 10GBASE-R or 25GBASE-R MACs via GTY transceivers
+
+## Board details
+
+* FPGA
+  * NT200A01: xcvu095-ffva2104-2-e
+  * NT200A02: xcvu5p-flva2104-2-e
+* 25GBASE-R PHY: Soft PCS with GTY transceivers
+
+## Licensing
+
+* Toolchain
+  * Vivado Enterprise (requires license)
+* IP
+  * No licensed vendor IP or 3rd party IP
+
+## How to build
+
+Run `make` in the appropriate `fpga*` subdirectory to build the bitstream.  Ensure that the Xilinx Vivado toolchain components are in PATH.
+
+## How to test
+
+Run `make program` to program the board with Vivado.
+
+To test the looped-back MAC, it is recommended to use a network tester like the Viavi T-BERD 5800 that supports basic layer 2 tests with a loopback.  Do not connect the looped-back MAC to a network as the reflected packets may cause problems.
+
+## JTAG pinout
+
+Napatech boards use a non-standard connector for JTAG.  There are three debug connectors, and one of them carries the JTAG signals for the FPGA.
+
+        J16             J22
+        FPGA            AVR
+    TDI 7 8 GND     TDI 7 8 GND
+    TMS 5 6 HALT    TMS 5 6
+    TDO 3 4 Vref    TDO 3 4 Vref
+    TCK 1 2 GND     TCK 1 2 GND
+
+            J17
+        GND 2 1
+            4 3
+            6 5
+
+Note: J18.6 HALT must be driven low to access the JTAG chain.  So, either tie to to ground, or connect it to the HALT signal on DLC9/DLC10 cables.

+
+Generic module for I2C bus initialization.  Good for use when multiple devices
+on an I2C bus must be initialized on system start without intervention of a
+general-purpose processor.
+
+Copy this file and change init_data and INIT_DATA_LEN as needed.
+
+This module can be used in two modes: simple device initialization, or multiple
+device initialization.  In multiple device mode, the same initialization sequence
+can be performed on multiple different device addresses.
+
+To use single device mode, only use the start write to address and write data commands.
+The module will generate the I2C commands in sequential order.  Terminate the list
+with a 0 entry.
+
+To use the multiple device mode, use the start data and start address block commands
+to set up lists of initialization data and device addresses.  The module enters
+multiple device mode upon seeing a start data block command.  The module stores the
+offset of the start of the data block and then skips ahead until it reaches a start
+address block command.  The module will store the offset to the address block and
+read the first address in the block.  Then it will jump back to the data block
+and execute it, substituting the stored address for each current address write
+command.  Upon reaching the start address block command, the module will read out the
+next address and start again at the top of the data block.  If the module encounters
+a start data block command while looking for an address, then it will store a new data
+offset and then look for a start address block command.  Terminate the list with a 0
+entry.  Normal address commands will operate normally inside a data block.
+
+Commands:
+
+00 0000000 : stop
+00 0000001 : exit multiple device mode
+00 0000011 : start write to current address
+00 0001000 : start address block
+00 0001001 : start data block
+00 001dddd : delay 2**(16+d) cycles
+00 1000001 : send I2C stop
+01 aaaaaaa : start write to address
+1 dddddddd : write 8-bit data
+

+# Taxi Example Design for NT20E3/NT40E3
+
+## Introduction
+
+This example design targets the Napatech NT20E3/NT40E3 FPGA board.
+
+The design places looped-back MACs on the SFP+ cages.
+
+*  SFP+ cages
+    *  Looped-back 10GBASE-R MACs via GTH transceivers
+
+## Board details
+
+*  FPGA: XC7VX330T-2FFG1157
+
+## Licensing
+
+*  Toolchain
+    *  Vivado Enterprise (requires license)
+*  IP
+    *  No licensed vendor IP or 3rd party IP
+
+## How to build
+
+Run `make` in the appropriate `fpga*` subdirectory to build the bitstream.  Ensure that the Xilinx Vivado toolchain components are in PATH.
+
+## How to test
+
+Run `make program` to program the board with Vivado.
+
+To test the looped-back MAC, it is recommended to use a network tester like the Viavi T-BERD 5800 that supports basic layer 2 tests with a loopback.  Do not connect the looped-back MAC to a network as the reflected packets may cause problems.
+
+## JTAG pinout
+
+Napatech boards use a non-standard connector for JTAG.  There are three debug connectors, and one of them carries the JTAG signals for the FPGA.
+
+        J18             J24
+        FPGA            AVR
+    TDI 7 8 GND     TDI 7 8 GND
+    TMS 5 6 HALT    TMS 5 6
+    TDO 3 4 Vref    TDO 3 4 Vref
+    TCK 1 2 GND     TCK 1 2 GND
+
+            J20
+        GND 2 1
+            4 3
+            6 5
+
+Note: J18.6 HALT must be driven low to access the JTAG chain.  So, either tie to to ground, or connect it to the HALT signal on DLC9/DLC10 cables.

+
+Generic module for I2C bus initialization.  Good for use when multiple devices
+on an I2C bus must be initialized on system start without intervention of a
+general-purpose processor.
+
+Copy this file and change init_data and INIT_DATA_LEN as needed.
+
+This module can be used in two modes: simple device initialization, or multiple
+device initialization.  In multiple device mode, the same initialization sequence
+can be performed on multiple different device addresses.
+
+To use single device mode, only use the start write to address and write data commands.
+The module will generate the I2C commands in sequential order.  Terminate the list
+with a 0 entry.
+
+To use the multiple device mode, use the start data and start address block commands
+to set up lists of initialization data and device addresses.  The module enters
+multiple device mode upon seeing a start data block command.  The module stores the
+offset of the start of the data block and then skips ahead until it reaches a start
+address block command.  The module will store the offset to the address block and
+read the first address in the block.  Then it will jump back to the data block
+and execute it, substituting the stored address for each current address write
+command.  Upon reaching the start address block command, the module will read out the
+next address and start again at the top of the data block.  If the module encounters
+a start data block command while looking for an address, then it will store a new data
+offset and then look for a start address block command.  Terminate the list with a 0
+entry.  Normal address commands will operate normally inside a data block.
+
+Commands:
+
