+# Taxi Example Design for HTG-ZRF8
+
+## Introduction
+
+This example design targets the HiTech Global HTG-ZRF8-R2 and HTG-ZRF8-EM FPGA boards.
+
+The design places looped-back MACs on the FMC+ for use with SFP and QSFP FMC adapters, as well as XFCP on the USB UART for monitoring and control.  The RF data converters are also enabled at 1 Gsps per channel.
+
+*  USB UART
+    *  XFCP (921600 baud)
+*  QSFP28
+    *  Looped-back 10GBASE-R or 25GBASE-R MACs via GTY transceivers
+
+## Board details
+
+*  FPGA: xczu48dr-ffvg1517-2-e
+*  USB UART: Silicon Labs CP2103
+
+## 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.
+
+## FMC
+
+All variants of the HTG-ZRF8 only connect 8 MGT lanes to the FMC+, DP0-7, so on some FMC/FMC+ boards, not all of the connectors will be usable.
+
+Another complicating factor is that the FMC+ connector has GA0/GA1 wired to ground, which causes an address conflict between the FMC EEPROM and any SFP/QSFP modules that can be connected to the FMC I2C pins.  Fixing the address conflict necessitates modification of either the FPGA board or the FMC board.
+
+Additionally, the HTG-ZRF8-EM only connects LA0-LA9, which can cause some problems with driving module control lines on FMC/FMC+.  In some cases, alternative approaches might be required to use a given FMC/FMC+, including module configuration via I2C as well as modifications to the FMC/FMC+ board.  
+
+This design has been tested with:
+
+*  HTG-FMC-QSFP28-DEG90
+    *  QSFP on DP0-3, DP4-7 not connected
+    *  resetl: on disconnected pin LA31_P, pulled high via R10 (OK)
+    *  lpmode: on disconnected pin LA32_N, pulled high via R3 (no good on -EM)
+    *  modsell: on disconnected pin LA31_N, pulled low via R8 (OK)
+
+Since the Si5341 PLL is directly connected to the MGTREFCLK pins for the sites connected to the FMC+, no reference clocks are required from the FMC+ and as such any reference PLL on the FMC does not need to be configured and any oscillators can be disabled.
+
+## Board configuration (HTG-ZRF8-R2)
+
+For correct operation, several DIP switches need to be set correctly.  Additionally, some other component-level modifications may be required.
+
+DIP switch settings:
+
+*  S2.1-4: all ON for JTAG boot
+*  S3.1: OFF (enable U19 outputs)
+*  S3.2: don't care (U19 IN_SEL1)
+*  S3.4: don't care (ON to disable PS ref clock)
+
+The PLL configuration in this design ignores the IN_SEL pins, so S3.2 has no effect.  The other DIP switches do not affect the operation of this design.  A simple "safe" configuration is S3 all OFF and S2 all ON.
+
+When using optical modules or active optical cables, it is necessary to pull the lpmode pins low and the resetl pins high to enable the lasers.  For I2C communication with the module, modsell must be pulled low.
+
+Additionally, the standard SFP/QSFP I2C address of 0x50 conflicts with the address 0 FMC EEPROM address.  The FMC address pins (GA0 and GA1) are controlled by R430/R411 and R441/R451.  See the table below for how to configure these resistors.
+
+| Address | R430 | R411 | R441 | R451 | 
+| ------- | ---- | ---- | ---- | ---- |
+| 0       | 0    | DNP  | 0    | DNP  |
+| 1       | DNP  | 4.7K | 0    | DNP  |
+| 2       | 0    | DNP  | DNP  | 4.7K |
+| 3       | DNP  | 4.7K | DNP  | 4.7K |
+
+## Board configuration (HTG-ZRF8-EM)
+
+For correct operation, several DIP switches need to be set correctly.  Additionally, some other component-level modifications may be required.
+
+DIP switch settings:
+
+*  S2.1: OFF (enable U48 outputs)
+*  S2.3: don't care (U48 IN_SEL0)
+*  S2.2: don't care (U48 IN_SEL1)
+*  S2.4: don't care (ON to disable PS ref clock)
+*  S3.1-4: all ON for JTAG boot
+
+The PLL configuration in this design ignores the IN_SEL pins, so S2.2 and S2.3 have no effect.  The other DIP switches do not affect the operation of this design.  A simple "safe" configuration is S2 all OFF and S3 all ON.
+
+When using optical modules or active optical cables, it is necessary to pull the lpmode pins low and the resetl pins high to enable the lasers.  For I2C communication with the module, modsell must be pulled low.  On the HTG-ZRF8-EM, only the first 20 LA pins (pairs LA0-LA9) are connected on the FMC+, so for some adapters, the lpmode and reset pins may not be connected to the FPGA.
+
+Additionally, the standard SFP/QSFP I2C address of 0x50 conflicts with the address 0 FMC EEPROM address.  The FMC address pins (GA0 and GA1) are controlled by R471/R472 and R478/R479.  See the table below for how to configure these resistors.
+
+| Address | R471 | R472 | R478 | R479 | 
+| ------- | ---- | ---- | ---- | ---- |
+| 0       | 0    | DNP  | 0    | DNP  |
+| 1       | DNP  | 4.7K | 0    | DNP  |
+| 2       | 0    | DNP  | DNP  | 4.7K |
+| 3       | DNP  | 4.7K | DNP  | 4.7K |
+
+## 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.

+
+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
+
+Examples

+
+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

+
+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
