How I Tested an FPGA-based BATS Parser using Python
LabVIEW FPGA Implementation of BATS PITCH I implemented a CBOE / BATS Market Data Parser by using LabVIEW FPGA, following the specification from the exchange: US Equities/Options Multicast Depth of Book (PITCH) Specification https://www.cboe.com/us/equities/support/technical/ https://cdn.cboe.com/resources/membership/US_EQUITIES_OPTIONS_MULTICAST_PITCH_SPECIFICATION.pdf to be more precise the parsing of most of the message types (no Options support) using LabVIEW FPGA a LabVIEW Host (non-FPGA)  parser and message generator to test my implementation a Python parser and message generator to validate: LabVIEW Host …
Vivado Simulator with Python Code
I know that Python is growing and growing in popularity… I hear it is more popular than learning French, at least according to this article: https://www.ocadogroup.com/media/press-releases/python-overtakes-french-most-popular-language-taught-primary-schools/ So I found this python module pysv, that advertises that it allows you to call Python from your SystemVerilog code: https://github.com/Kuree/pysv As of today – January 3rd, 2024 – it has a few issues: Poor windows support No support for passing native Python lists This issue says that lists …
Error While Running Vivado Simulation on Ubuntu 22.04
So I was recently playing around with DPI (Direct Programming Interface) in Vivado Simulator.  My goal is to call some python code that I wrote that will generate valid BATS messages, pass that data into my IP, and check the parsed code coming out is correct. After reading through the Xilinx/AMD documentation, I went ahead and used some Python to SystemVerilog and tried to run some sample code and eventually came upon an error complaining …
Vivado Hangs during Installation on WSL/Linux
Long story, but I decided to try out/start using Vivado using Linux. After confirming that X11 was working on my WSL installation of Ubuntu 22.04, I decided to download the latest version of Vivado and to install it for Linux. During the installation, towards the end the installation hangs at "Generating installed device list" Xilinx/AMD has an answered question here:https://support.xilinx.com/s/question/0D52E00006hpmTmSAI/vivado-20183-final-processing-hangs-at-generating-installed-device-list-on-ubuntu-1904?language=en_US Here is what I did to resolve this: First, remove the files of my existing …
How to use LabVIEW FPGA IP Integration Node
I made a quick YouTube playlist describing how to use the IP Integration Node to import: a single vhdl file from a Vivado project via a Netlist (.edn) file a single vhdl file from a Vivado project via a Design Checkpoint (.dcp) file a block design with custom Xilinx IP (AdderSubtractor) from a Vivado project via a Design Checkpoint (.dcp) file I made a YouTube playlist: https://www.youtube.com/watch?v=oZ_Xy_TYXHw&list=PLRkNZWVdUmb-6_pEby_dkiIdRa-UOXL4I You can browse the source code related to …
BATS Parser Description
BATS.Parser The BATS.Parser has the following interface: Source Code: LabVIEW FPGA: https://github.com/fpganow/cboe_pitch_lv_fpga/tree/main/cboe_pitch/fpga/bats.parser LabVIEW Host Tests: https://github.com/fpganow/cboe_pitch_lv_fpga/tree/main/cboe_pitch/host/bats.parser Inputs: Reset [Bool] Data [U8[8]] Data.Valid [Bool] Ready.For.Debug [Bool] Ready.For.OrderBook.Command [Bool] Outputs: Ready.For.Udp.Input [Bool] Debug.Element [U64] Debug.Valid [Bool] OrderBook.Command OrderBook.Command.Type [Cluster] Side [U8] Order Id [U64] Quantity [U32] Symbol [U64] Price [U64] Executed Quantity [U32] Canceled Quantity [U32] Remaining Quantity [U32] Seconds [U64] Nanoseconds [U64] OrderBook.Command.Valid [Bool] The BATS.Parser IP is expecting UDP (or TCP) application-level data coming from …
BATS/CBOE Pitch Feed Handler/Normalizer is Ready
I have spent a lot of my free time developing this over the past 4-5 months.  I am busy working on an actual 'demo', so I will be brief.  The code for a BATS/CBOE Pitch message parser/feed handler is ready.  If you know LabVIEW, you are lucky, if you don't, you will have to watch an upcoming video of mine and to follow along closely… If you have LabVIEW, (you can download a free evaluation …
New Theme
I spent some time re-organizing this site to make it easier on the eye, easier to navigate and to be more organized in general. I also figured out a way to run this site using Docker with a MariaDB backend that I can easily back up, download to any of my home mac or windows desktops, run it locally, make a lot of changes and re-upload it when necessary.  Maybe I should make a post …
Part 4 – OrderBook Now Published
Part 4 of the Smart FPGA Nic, dealing with the OrderBook has been published. Go here to see more: https://fpganow.com/index.php/part-4-order-book/ Related source code: https://github.com/fpganow/arty_bats/tree/main/labview/arty/orderbook As I make updates to the code, mainly to make it prettier and easier for others to follow, I will make new a post for each change detailing all changes.  
How to Parse BATS Market Data Messages
I just created a 'Page' as opposed to a WordPress 'Post' documenting how I was able to parse BATS Market Data messages. This new style or format will be much better than my writing multiples posts.  Easier for the reader to find, and easier for me to find and to update an article. Anyway, look above, under the "SMART 'FPGA-NIC'" menu above to find Part 2: Parse BATS Messages in an FPGA. (I never made …
Xilinx Vivado and Source Control
Related Source Repository: https://github.com/fpganow/vivado_scm Xilinx Vivado does not come with built-in source control.  If you are a Visual Studio user, or a IntelliJ IDEA or eclipse user, you may be familiar with using some sort of IDE-related source code control. Vivado has a different paradigm for source control: Export commands to re-generate the project as a tcl script. Add tcl and all related files to source-control After I tried following a lot of guides that …
Dealing with the Vivado [DRC INBB-3]’ Black Box Instances’ issue
So my workflow is as follows: Create IP in NI LabVIEW FPGA Export via FPGA IP Export Tool Creates a VHDL wrapper (.vhd) Places IP in Design Checkpoint (.dcp) file Open my Vivado Block Design Use or update the VHDL wrapper that uses the Design Checkpoint Synthesis, Implementation, and Run The NI LabVIEW FPGA IP Export utility provides you with 2 files, a design checkpoint and a wrapper file to use for instantiating your IP …
Okay, Parsing UDP in LabVIEW FPGA Works
I got something working – with live hardware plugged in to my network. I used the larger version of the Arty Artix-7 board, which cost $250 USD, and made my own custom reader for the LabVIEW FPGA Network library.  I did not implement network writing features, nor do anything with the payload.  Nevertheless, this is a Proof-of-Concept and can be used to make a nice FPGA accelerated network application. Anyway, follow these instructions if you …
Vivado Error [Opt 31-67], and How I Fixed It.
So I am dealing with the following scenarios: Scenario 1 – Genesys Zynq with SYZYGY SFP I have the Genesys Zynq UltraScale+ MPSoC 3EG board that does not provide direct access to the PHY pins, but has a SYZYGY port that I have plugged in to the SZG-DUALSFP module with an SFP connector. Scenario 2 – Arty A7 Artix-7 with 10/100 Mbit PHY I have the Arty A7 Artx-7 FPGA Development Board that gives me …
Plans Using Arty Artix-7
Here is the new plan: Step 1 – Create a design using a MicroBlaze processing system, enable a UART connection and listen on an AXI FIFO and dump packets to the screen as they are received in chunks of X bytes. Step 2 – Insert some LabVIEW FPGA code to send one packet of data every second. Step 3 – Replace this LabVIEW FPGA code to listen to the MII Ethernet interface pins and to …
And Another Alternative
I no longer have to look into figuring out how to code up or wire up the SZG-DUALSFP daughter board to the Digilent Genesys Zynq UltraScale MPSoC+ board. Why? Because I have a really old board that cost only $99 dollars that gives me direct access to the pins of an old 10/100 MBit PHY! That's the Arty Artix-35T mini board! Anyway… I found a corresponding NI "no longer national instruments" board that targets the …
Rebuilding Genesys Zynq UltraScale MPSoC+ Out of Box Demo
So I spent some time to rebuild the out-of-box demo for the Genesys Zynq UltraScale MPSoC+ board.  Not everything worked for me right away, so I made this post to include all the things I did to get it to work.: My system: Windows 10 Windows Subsystem for Linux 2 Ubuntu 18.04 (<= Ubuntu 20 does not work unless you make a lot of changes) References: Schematics https://reference.digilentinc.com/_media/reference/programmable-logic/genesys-zu/genesys_zu-3eg_sch_public.pdf Official Documentation from Digilent Official Getting Started …
SZG-DUALSFP Update
I went to the Opal Kelly website again and noticed that there are a lot of menu options that I previously did not notice at the top menu. I found a sample board that uses their SZG-DUALSFP board: https://opalkelly.com/products/xem7320/ So now I can read the documentation for this board and be on my way! I also had some fun reading the specification documents for the SYZYGY specification, the SZG-DUALSFP board, and for the Finisar Tranceiver …
SZG-DUALSFP Howto?
So I have the Genesys Zynq UltraScale + MPSoC board, I bought the SZG-DUALSFP from Opel Kelly, and I want to figure out how to wire this thing up. What pin goes where? I dunno.  I spent some time reading the SFP+ specification.  Everything makes sense.  Then I read through the SYZYGY specification.  Again, things make sense. So what does the interface look like? Anybody know? One though is to look at a sample from …
Zynqberry Board Pause
After my previous post showing how to use the NI LabVIEW FPGA IP Export Utility to run LabVIEW FPGA code on a Zynqberry (http://fpganow.com/index.php/2020/09/28/zynqberry-with-breakout-board-and-labview/), I continued following the examples I could find on the internet and was able to connect to the board by using the PS (Processing System) built-int UART, and to communicate to the GPIO by using C code. Then I wanted to access the PHY or the ETH pins directly and to …

FPGAs are ultra-specialized, low-power, and really fast custom-processors that can dramatically reduce both your latency and your power consumption, yet they take a really long time to develop using traditional HDL tools. Using the right set of tools one can develop FPGA solutions in a timely fashion.
