README
README.mdTime Distribution System for Lab Based Experiments
This project implements a time distribution system for laboratory based experiments using pulsed lasers. It consists of a transmitter and several receivers. The transmitter generates a unique pulse-id number for each laser pulse. This pulse-id, together with configuration information is transmitted to the receivers over twisted-pair cables (use Cat 6A cables only!). A magnetic RAM is used to store the last value and to recover after a power outage.
The receivers decode the pulse-id send it to FPGAs on individual instruments (framegrabber boards, digitizers, ...) for time stamping the data. In addition, the receivers generate low-jitter trigger signals. These can be configured from the transmitter.
The project contains the following components:
- Boards: Schematics and layouts of the printed circuit boards for the receiver and transmitter
- Firmware: Logic on the FPGAs as well as firmware running on an embedded RISC-V processor for the transmitter and receivers
- Tango: Device servers for the transmitter and to configure the trigger channels of the receivers (see tango-controls.org)
- Notes: Presentation with the block diagrams of the system
Requirements:
- For simulating the individual components of the firmware: Cocotb, Verilator
- For synthesis: Quartus (intel) v. 23.1 standard edition
- For the software on the RISC-V: gcc for RV32IM (see https://github.com/SpinalHDL/VexRiscv)
- Tango control system: https://tango-controls.org
The project contains the following 3rd party components: Firmware:
- CRC generator (https://github.com/hellgate202/crc_calc.git)
- Softcore: Based on the VexRiscV project (https://github.com/SpinalHDL/VexRiscv)
- TinyDuino_lib: developed by Domenic Wüthrich as a semester project at ETH Zurich, institute for integrated systems.

Questions
How big is the Transmitter PCB?
It measures 160 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Transmitter use?
279 parts, built around the SN74LV1T34DBV, SN65LVDS1DBV, LM321 and NB3L8504SDT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Transmitter KiCad files?
From the yacremann/TimeDistributionSystem repository on GitHub, at the commit this page was made from: the board is Boards/Transmitter/Transmitter.kicad_pcb and its schematic Boards/Receiver/CDR_PLL.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Transmitter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
