HRM-TDC
USER MANUAL
High Resolution Time-to-Digital Converter Module

Document Overview

This document provides the user with a comprehensive
description of the hardware and software of the HRM-
TDC module, including system description, the various
timing modes, software GUI and DLL drivers. The
document is split up into the following sections:

GETTING STARTED

This section provides instructions for unpacking the HRM-TDC and a brief overview.
SYSTEM DESCRIPTION
This section gives a description of the system hardware, the various ports and communication channels, the internal
processor, and the specific timing features.
SENSL INTEGRATED ENVIRONMENT (SIE)
The SIE is a user interface for setting up and controlling the HRM-TDC module. While the interface provides an
extensive range of operating modes and measurement processes, including graphical presentation, it does not fully
cover all features available in the HRM-TDC module. This section of the User Manual includes instructions for the
installation of the necessary software, and detailed description of each part of the SIE and how to set up and use it.
APPENDIX
The HRM-TDC DLL provides a set of functions that will allow full control of the HRM-TDC for all features. For
complex experiments that require control beyond the scope of the SIE, it is expected that the user will write their own
real-time application utilizing the various functions in this DLL. The Appendix of the User Manual covers Registers,
low level DLL functions, high level DLL functions, DLL error reporting and examples, as well as help and examples
for resolving time-tag values,an explanation of the correlation function used and the Labview drivers provided.

  • Page 5: Glossary

    SensL Integrated Environment - the GUI that runs on the SensL DLL and provides an example SIE - program allowing the user to make measurements with the HRM-TDC. Least Significant Bit: The right most bit in a binary integer, and in the case of the HRM-TDC LSB - it determines the minimum timing resolution possible.

  • Page 9: Hrm-Tdc System Description

    High Speed USB 2.0 Interface The USB interface is used to command/configure the HRM-TDC as well as download, in real-time, timing data to the host computer. This USB interface implements high speed USB 2.0 protocol allowing real time continuous logging of timing data up to rates of 4.5MHz without data loss.

  • Page 10: 16-Bit General Purpose I/O Port

    This module is responsible for receiving a set of commands from the host computer and controlling the system accordingly. HRM-TDC is a fully programmable system with a wide range of parameters that can be user defined. The Command Interpreter is responsible for setting these parameters and starting the execution of a particular task.

    HRM-TDC USER MANUAL > Hrm-tdc System Description > System Processor And Controller Detailed Description DMA to USB Fast Transfer Interface The system memory is dual ported between the USB and the Time-Bin/Time-Tag controller. This module controls the reading of data from memory to the USB interface by means of high speed DMA block transfers. The Command Interpreter initializes this module with a start address and block data count.

  • Page 12: Hrm-Tdc Specific Feature Overview

    HRM-TDC SPECIFIC FEATURE OVERVIEW The flexibility of the HRM-TDC allows it to be used in a variety of modes. The following are examples of how the SIE software utilizes the START and STOP signals in different ways to cater for different applications.

  • Page 13: Histogram

    HRM-TDC USER MANUAL > Hrm-tdc System Description > Hrm-tdc Specific Feature Overview HISTOGRAM Histogram modes use consecutive memory locations to store counts that represent points on a graph. These memory locations or time bins are incremented based on the value of a time measurement. Each memory location represents a time range equal to the resolution of the timer.

  • Page 14: Histogram - Single-Stop ("Tcspc" Mode)

    HRM-TDC USER MANUAL > Hrm-tdc System Description > Histogram – Single-stop (“tcspc” Mode) HISTOGRAM – SINGLE-STOP (“TCSPC” MODE) Fig.1c Figure 5 Histogram modes use consecutive memory locations to store counts that represent successive timing values (Fig.5a). These memory locations or “time bins” are incremented based on the result of a time measurement between a START and the first STOP received.

  • Page 15: Histogram - Multi-Stop ("Multiscaler/Counter")

    HRM-TDC USER MANUAL > Hrm-tdc System Description > Histogram – Multi-stop (“multiscaler/counter”) HISTOGRAM – MULTI-STOP (“MULTISCALER/COUNTER”) Fig.2b Figure 6 In this mode, multiple STOP events following a single START event are recorded and their corresponding time bins in the histogram incremented (Fig.6a). The following START input will reset the timer and the following STOP events will be again recorded until another START is received.

    HRM-TDC USER MANUAL > Hrm-tdc System Description > Fifo – Single-stop (“tcspc - With Macro-time”) FIFO – SINGLE-STOP (“TCSPC - WITH MACRO-TIME”) Fig.3c Fig.3d Figure 7 FIFO modes continually record the timing of events and save the results in consecutive locations in memory as shown in Fig.7a.

    HRM-TDC USER MANUAL > Hrm-tdc System Description > Fifo – Multi-stop (“fifo - Time Tagging”) FIFO – MULTI-STOP (“FIFO - TIME TAGGING”) Fig.4b Fig.4c Figure 8 In this mode the process is started with a single START pulse. The module will then fill the memory with time tags defining the time of each STOP event with relation to the initial single START pulse.

  • Page 21 HRM-TDC USER MANUAL > Sensl Integrated Environment (sie) > Using The Sensl Integrated Environment (sie) Reverse Plot Due to the method of TCSPC measurement, where the start and stop events are reversed, it is sometimes useful to plot the curves with the TIME axis reversed. Selecting this option will reverse the time axis for the plot.

    The size of the configuration and graph area can be adjusted by dragging the partition to suite. This page is a graphical demonstration of the TCSPC with MACRO time feature of the HRM-TDC module. The HRM- TDC allows the user to carry out TCSPC and save time tags. These time tags consist of the TCSPC measurement plus a MACRO time defining at what time during the experiment the measurement was made.

As can be seen in Fig 14, the time-tags are repeating every 200 counts of the MACRO time. As the resolution of the MACRO time was set to 5ns, this represents a repetition rate of 1ms (200 x 5 ns).

Once the configuration is selected, the user can start the module recording. The module will wait for the first Start pulse and then start recording every stop event until the recording time is reached, the maximum event count is reached or the process is manually stopped.

  • Page 32: Appendix

    HRM-TDC REGISTERS AND LOW LEVEL DLL FUNCTIONS The control and setup of the HRM-TDC is carried out by a series of commands to a set of configuration registers within the module. To simplify the control of these registers, a set of low level drivers, in a DLL, is available. The low level drivers will return an HRM_STATUS of value HRM_OK or HRM_ERROR.

  • Page 33: Arr - Address Route Register

    On receipt of a time-tag the system outputs the time-tag as an address and then increments that location (time-bin). In the HRM-TDC system further data bits are included in the address selection to allow multiple curve plotting based on multiple channel inputs and discrete inputs for X, Y array plotting.
  • Page 34 IODATA(0) and the line counter is incremented by clock inputs to IODATA(1). If these bits are routed to the address lines then the user can command the HRM-TDC module to move from one curve to the next by clocking the IODAT(0) and IOADAT(1) lines.

  • Page 35: Drr - Data Route Register

    DRR – Data Route Register Register Description When the HRM-TDC system is in time-tag mode it will continually save time-stamps to memory. Each time-stamp will always be 32-bits, however the format of the time-stamp is programmable using the DRR. To allow maximum flexibility the DRR register can define any ‘Data Option Bit’...
