+\section{General Description}
+The 1124 Kasli 2.0 Carrier card is an 8hp EEM module, designed to run ARTIQ kernels sent from a host machine over the network. It supports up to 12 EEM connections to other EEM cards in the ARTIQ-Sinara family and up four SFP connections, used for comunications with other carriers and/or Ethernet.
+
+Real-time control of EEM daughtercards is implemented using the ARTIQ RTIO system. 1ns temporal resolution can be achieved for TTL events.
+
+4 SFP 6Gb/s slots are provided. One may be used for Ethernet, which supports communication with a host machine. Remaining slots can be used by the ARTIQ Distributed Real-Time Input/Output (DRTIO) system, which allows for the use of additional core devices (e.g. Kasli 2.0, Kasli-SoC) as satellite cards, capable of running subkernels or distributing commands from the \mbox{DRTIO} master.

+\section{Electrical Specifications}
+External clock parameters are derived based on the internal termination specified in
+UG471\footnote{\label{ug471}\url{https://docs.xilinx.com/v/u/en-US/ug471\_7Series\_SelectIO}}
+and the voltage range specified in
+DS181\footnote{\label{ds181}\url{https://docs.xilinx.com/v/u/en-US/ds181\_Artix\_7\_Data\_Sheet}}. These figures account for the insertion loss of the RF transformer (TC2-1TX+\footnote{\label{rf_trans}\url{https://www.minicircuits.com/pdfs/TC2-1TX+.pdf}}).

+
+Power is to be supplied through the barrel connector in the front panel, size 5.5 mm OD, 2.5 mm ID, and is passed on to daughtercards through the EEM connections. Locking barrel connectors are supported.
+
+\section{FPGA}
+
+Kasli 2.0 features an XC7A100T-3FGG484E Xilinx Artix-7 FPGA to facilitate reconfigurable high-speed real-time control of inputs and outputs. Most commonly, this FPGA is flashed with binaries compiled from the ARTIQ (Advanced Real-Time Infrastructure for Quantum physics) control system, which equips the carrier board with specialized gateware for handling other Sinara EEMs and an on-FPGA CPU for running ARTIQ experiment \mbox{kernels}.
+
+ARTIQ is open-source and can be found in the repository \url{https://github.com/m-labs/artiq}. Orders of Sinara hardware are normally accompanied with precompiled binaries. Long-term support for ARTIQ systems can also be purchased.
+
+A micro-USB located on the front panel is equipped for JTAG, I2C, and UART serial output. The serial interface runs at 115200bps 8-N-1.
+
+\subsection{Note on distributed RTIO (DRTIO)}
+
+DRTIO is the time and data transfer system that allows ARTIQ RTIO channels to be distributed among several core device carrier boards, synchronized and controlled by a central core device. The system itself is more fully described in the ARTIQ documentation\footnote{\label{manual-drtio}\url{https://m-labs.hk/artiq/manual/drtio.html}}. With ARTIQ firmware/gateware, supported core devices, including Kasli 2.0, can take one of three roles:
+\begin{enumerate}
+    \item \textbf{Master} \\
+    The DRTIO master is unique in a DRTIO system. It requires a direct network connection to the host machine. It may make downstream connections to satellites. It controls its own local RTIO channels and the downstream DRTIO satellite(s).
+    \item \textbf{Satellite} \\
+    Any other core devices in a DRTIO system are DRTIO satellites. They require an upstream connection to one other core device, master or satellite, through which communications will ultimately be chained to the master. They may make further downstream connections to other satellites. They may control RTIO channels through subkernels or simply pass on communications from the master.
+    \item \textbf{Standalone}\\
+    When run in a non-distributed ARTIQ configuration, with a single central core device but no satellites, that core device is instead known as standalone.
+\end{enumerate}
+
+\section{Communication Interfaces}
+
+Communication between devices is implemented using 1000Base-T small form-factor pluggable (SFP) interfaces. Four are available on the Kasli 2.0. Appropriate SFP transceivers must be plugged inside the corresponding SFP cages. Each SFP connector possesses an indicator LED.
+
+\subsection{Upstream connection}
+
+A Kasli 2.0 board must acquire an upstream connection through the \texttt{SFP0} slot.
+
+\begin{itemize}
+    \item \textbf{Standalone/Master} \\
+    An Ethernet-capable SFP transceiver should be inserted into the \texttt{SFP0} slot. Typically, a 10000Base-X RJ45 SFP module is used, with an network-connected Ethernet cable attached to the module.
+    \item \textbf{Satellite} \\
+    The \texttt{SFP0} port should be connected to one of the free SFP slots on an upstream core device, using a cable connection with SFP transceivers.
+\end{itemize}
+
+\subsection{Downstream connection}
+Kasli 2.0 supports up to 3 DRTIO satellite connections per device. Any of the 3 downstream SFP ports (i.e. \texttt{SFP1}, \texttt{SFP2}, \texttt{SFP3}) may be used.
+
+\section{Clock Routing}
+\subsection{Standalone/Master}
+The RTIO clock is typically synthesized by the Si5324 clock multiplier and distributed by the ADCLK948 clock fanout buffer to both the FPGA and the MMCX connectors. Alternatively, an external reference can be supplied through the front panel SMA connector. It is then buffered in the FPGA and sent to the Si5324 for clock synthesis. Kasli 2.0 supports a set of RTIO clock options:
+\begin{table}[H]
+    \centering
+    \begin{tabular}{|c|c|c|}
+    \hline
+    RTIO frequency           & Configuration          & Clock generation                                                \\ \hline
+    100 MHz                  & \texttt{int\char`_100}               & internal crystal oscillator using PLL, 100 MHz output           \\ \hline
+    \multirow{4}{*}{125 MHz} & \texttt{int\char`_125}               & internal crystal oscillator using PLL, 125 MHz output (default) \\ \cline{2-3}
+                             & \texttt{ext0\char`_synth0\char`_10to125}  & external 10 MHz reference using PLL, 125 MHz output             \\ \cline{2-3}
+                             & \texttt{ext0\char`_synth0\char`_100to125} & external 100 MHz reference using PLL, 125 MHz output            \\ \cline{2-3}
+                             & \texttt{ext0\char`_synth0\char`_125to125} & external 125 MHz reference using PLL, 125 MHz output            \\ \hline
+    150 MHz                  & \texttt{int\char`_150}               & internal crystal oscillator using PLL, 150 MHz output           \\ \hline
+    \end{tabular}
+    \end{table}
+
+The clock synthesizer may also be bypassed, using the \texttt{ext0\char`_bypass} option, which will accept a RTIO clock directly supplied to the SMA connector. The resulting signal is then routed to both the RTIO system and downstream satellites.
+
+Clocking options in a running system should be configured by setting the value of the \texttt{rtio\char`_clock} key to the desired configuration through \texttt{artiq\char`_coremgmt}. For example, a RTIO frequency of 125MHz will be synthesized from an external 10 MHz signal after issuing the following command:
+
+\begin{minted}{bash}
+    artiq_coremgmt config write -s rtio_clock ext0_synth0_10to125
+\end{minted}
+
+and rebooting.
+
+\subsection{Satellite}
+The RTIO clock is recovered from the SFP transceiver connected to the upstream device. The resulting signal is then cleaned up by the Si5324 and routed to both the RTIO system and downstream satellites.
+
+\subsection{WRPLL}
+
+Kasli 2.0 can be configured to use WRPLL, a clock recovery method making use of White Rabbit's DDMTD (Digital Dual Mixer Time Difference) and the card's Si549 oscillators, both to lock the main RTIO clock and to lock satellite clocks to master.
+
+\section{User LEDs}
+
+Kasli 2.0 supplies three user LEDs for debugging purposes. Two are located on the front panel. The third is located on the PCB itself, beside the SFP cage. An additional ERR LED on the front panel is used by ARTIQ firmware to indicate a runtime panic.
+
+\newpage
+
+\codesection{Kasli 2.0 1124 carrier}
+
+\subsection{Direct Memory Access (DMA)}
+Instead of directly emitting RTIO events, sequences of RTIO events can be recorded in advance and stored in the local SDRAM. The event sequence can then be replayed at a specified timestamp. This is of special advantage in cases where RTIO events are too closely placed to be generated as they are executed, as events can be replayed at a higher speed than the on-FPGA CPU alone is capable of.
+
+The following example records an LED event sequence and replays it twice consecutively using \texttt{CoreDMA}. When run, the LED should blink twice.
+
+\inputcolorboxminted{firstline=10,lastline=29}{examples/dma.py}
+
+Stored waveforms can be referenced and replayed in different kernels, but cannot be retrieved and must be regenerated if the core device is rebooted.
+
+\newpage
+
+\subsection{Dataset manipulation with core device cache}
+Experiments may require values computed or found in previously executed kernels. To avoid invoking an RPC or sacrificing the pre-computation in \texttt{prepare()} stage, data can be stored in the core device cache.
+
+The following code snippets describe two experiments, in which the data from the first experiment is cached. The data is then retrieved and printed in hexadecimal form in the second experiment.
+
+\inputcolorboxminted{firstline=9,lastline=16}{examples/cache.py}
+\inputcolorboxminted{firstline=24,lastline=35}{examples/cache.py}
+
+Similar to DMA, cached data is no longer retrievable once the core device has been rebooted.

 \section{Configuring IO Direction \& Termination}
-The termination and IO direction can be configured by switches.
-The per-channel termination and per-bank IO direction switches are found at the middle-left and middle-right of both cards respectively.

-They do not exhaustively demonstrate all the features of the ARTIQ system.
-The full documentation for the ARTIQ software and gateware is available at \url{https://m-labs.hk}.
 
-Timing accuracy in the examples below is well under 1 nanosecond thanks to the ARTIQ RTIO system.
+Timing accuracy in these examples is well under 1 nanosecond thanks to ARTIQ RTIO infrastructure.
 
 \subsection{One pulse per second}
 The channel should be configured as output in both the gateware and hardware.

-\subsection{Sub-coarse-RTIO-cycle pulse}
-With the use of the ARTIQ RTIO, only 1 event can be enqueued per coarse RTIO cycle, which is typically 8ns.
-Therefore, to emit a pulse that is less than 8ns, additional delay is needed such that the \texttt{ttl.on()} \& \texttt{ttl.off()} event are submitted at different coarse RTIO cycles.
-The TTL pulse must satisfy the minimum pulse width stated in the electircal specifications.

+\newpage
-The channel should be configured as input in both the gateware and hardware.
+\subsection{Sub-coarse-RTIO-cycle pulse}
-\inputcolorboxminted{firstline=47,lastline=52}{examples/ttl.py}
+With the use of ARTIQ RTIO, only one event can be enqueued per \textit{coarse RTIO cycle}, which typically corresponds to 8ns. To emit pulses of less than 8ns, careful timing is needed to ensure that the \texttt{ttl.on()} \& \texttt{ttl.off()} event are submitted during different coarse RTIO cycles.
 
-This example code uses the software counter, which has a maximum count rate of approximately 1 million events per second.
+\inputcolorboxminted{firstline=60,lastline=64}{examples/ttl.py}
-If the gateware counter is enabled on the TTL channel, it can typically count up to 125 million events per second:
-\inputcolorboxminted{firstline=60,lastline=65}{examples/ttl.py}
 
-To count falling edges or both rising \& falling edges, use \texttt{gate\char`_falling()} or \texttt{gate\char`_both()}.
+\subsection{Edge counting in a 1ms window}
+The \texttt{TTLInOut} class implements \texttt{gate\char`_rising()}, \texttt{gate\char`_falling()} \& \texttt{gate\char`_both()} for rising edge, falling edge, both rising edge \& falling edge detection respectively.
+The channel should be configured as input in both gateware and hardware. Invoke one of the 3 methods to start edge detection.
+\inputcolorboxminted{firstline=14,lastline=15}{examples/ttl_in.py}
+Input signal can generated from another TTL channel or from other sources. Manipulate the timeline cursor to generate TTL pulses using the same kernel.
+\inputcolorboxminted{firstline=10,lastline=22}{examples/ttl_in.py}
+The detected edges are registered to the RTIO input FIFO. By default, the FIFO can hold 64 events. The FIFO depth is defined by the \texttt{ififo\char`_depth} parameter for \texttt{Channel} class in \texttt{rtio/channel.py}.
+Once the threshold is exceeded, an \texttt{RTIOOverflow} exception will be triggered when the input events are read by the kernel CPU.
+Finally, invoke \texttt{count()} to retrieve the edge count from the input gate.
+
+The RTIO system can report at most one edge detection event for every coarse RTIO cycle. In principle, to guarantee all rising edges are counted (with \texttt{gate\char`_rising()} invoked), the theoretical minimum separation between rising edges is one coarse RTIO cycle (typically 8 ns). However, both the electrical specifications and the possibility of triggering \texttt{RTIOOverflow} exceptions should also be considered.
 
 \newpage
+\subsection{Edge counting using \texttt{EdgeCounter}}
+This example code uses a gateware counter to substitute the software counter, which has a maximum count rate of approximately 1 million events per second. If a gateware counter is enabled on the TTL channel, it can typically count up to 125 million events per second:
+\inputcolorboxminted{firstline=31,lastline=36}{examples/ttl_in.py}
+Edges are detected by comparing the current input state and that of the previous coarse RTIO cycle. Therefore, the theoretical minimum separation between 2 opposite edges is 1 coarse RTIO cycle (typically 8 ns).
+
 \subsection{Responding to an external trigger}
 One channel needs to be configured as input, and the other as output.

 \subsection{62.5 MHz clock signal generation}
-A TTL channel can be configured as a \texttt{ClockGen} channel, which generates a periodic clock signal.
+A TTL channel can be configured as a \texttt{ClockGen} channel, which generates a periodic clock signal. Each channel has a phase accumulator operating on the RTIO clock, where it is incremented by the frequency tuning word at each coarse RTIO cycle. Therefore, jitter should be expected when the desired frequency cannot be obtained by dividing the coarse RTIO clock frequency with a power of 2.

+\subsection{Minimum sustained event separation}
+The minimum sustained event separation is the least time separation between input gated events for which all gated edges can be continuously \& reliabily timestamped by the RTIO system without causing \texttt{RTIOOverflow} exceptions. The following \texttt{run()} function finds the separation by approximating the time of running \texttt{timestamp\char`_mu()} as a constant. Import the \texttt{time} library to use \texttt{time.sleep()}.

+The 5518 BNC-IDC card is a 8hp EEM module; the 5528 SMA-IDC card is a 4hp EEM module. Both adapter cards break out analog signals from IDC connectors to BNC (5518) or SMA (5528). IDC connectors can be found on 5108 Sampler, 5432 DAC Zotino, 5632 DAC Fastino and 5568 HD68-IDC.
-Both adapter cards break out analog signal from IDC connectors to BNC (5518) or SMA (5528).
-IDC connectors can be found on 5108 Sampler, 5432 DAC Zotino, 5632 DAC Fastino \& 5568 HD68-IDC.
 
-Each card provides 8 channels, with BNC (5518) or SMA (5528) connectors.
+Each card provides 8 channels, with respectively BNC or SMA connectors. Breaking out all 32 channels of 5432 DAC Zotino, 5632 DAC Fastino or 5568 HD68-IDC requires four BNC/SMA-IDC cards. Breaking out all 8 ADC channels of 5108 Sampler requires only one BNC/SMA-IDC card.
-Breaking out all 32 channels from 5432 DAC Zotino, 5632 DAC Fastino or 5568 HD68-IDC requires 4 BNC/SMA-IDC cards.
-Only 1 BNC/SMA-IDC is required to break out all 8 ADC channels from a 5108 Sampler.
