rx_err (1 bit per port) - asserted to indicate an abnormal frame termination condition.

You can assume that rx_sof, rx_early_sof and rx_eof are always valid.

Due to the overhead of the 64b/66b encoding used in 10G Ethernet, there may be cycles intra-frame that do not contain valid data. rx_vld (1 bit per port) - asserted to indicate that receive data is valid.If it reads 0, then there are no more valid bytes in this cycle and the packet effectively finished in the previous cycle. As an example, if this reads 1, then only the bottom byte of data (bits 7 to 0) is valid.

rx_len (2 bits per port) - asserted on the same cycle as the EOF, indicates how many bytes in the final data signal are valid.The last bytes seen will include the four byte received CRC. rx_eof (1 bit per port) - asserted on the very last cycle of a received frame.rx_early_sof (1 bit per port) - a 'heads up' that the start of the preamble has been received and that rx_sof will be asserted in 2-3 cycles.

rx_data will contain the first byte of the destination MAC address. rx_sof (1 bit per port) - asserted on the same cycle as the first data word received from the wire.The first byte appears at byte 0 (bits 7 to 0). rx_data (32 bits per port) - packet data as received from the wire.The received data is provided via the following signals, all of which are inputs: This will also introduce an additional register stage for the 10G PCS/MAC TX path in order to achieve timing closure. Support for 100M & 1G: Specifies whether 100M and 1G PCS/MAC is included in the FDK.If this register is added, crc_flag is valid 2 cycles after eof, otherwise it's valid on the cycle after eof. This improves timing closure, but delays the assertion of the crc_fail flag. Extra CRC Reg: Specifies whether an additional register stage is added to CRC RX path.If this additional register is not included, the MAC latency will improve by 3.1ns, however it will make timing closure more difficult. This does not impact the user interface/timing diagrams. Extra RX Reg: Specifies whether an additional register stage is added to the internal MAC RX path.The minimum value is 8 and the maximum is 48. Number of Ports: Specified the number of ports that are enabled in Fusion.

FDK Type: Specifies whether this FDK is a Full or Demo.

Codi!! toggles Codi for the current buffer, using the provided filetype or the buffer's filetype.Ī nice way to use Codi is through a shell wrapper that you can stick in your ~/.There are several build options that are available for the FDK that Exablazeneeds to set at the FDK build time, rather than at the customer's build time.The file buildlog contains information as to what the build options were setto at the time the particular FDK was generated by Exablaze.

Codi! deactivates Codi for the current buffer.

Codi activates Codi for the current buffer, using the provided filetype or the buffer's filetype.

Haskell: ghci (be really careful with lazy evaluation!).

For example, if you only want to use the Python Codi interpreter, you will not need ghci.

If not using NeoVim, script (BSD or Linux, man page should say at least 2013)Įach interpreter also depends on its REPL.

Vim 7.4 (with +job and +channel for asynchronous evaluation) or NeoVim (still in its infancy - please report bugs!).

OS X or Linux (Windows support coming soon!).

Use your favorite package manager ( vim-plug, Vundle, pathogen.vim), or add this directory to your Vim runtime path.įor example, if you're using vim-plug, add the following line to ~/.vimrc: Note: without async support, evaluation will trigger on cursor hold rather than text change.įor more information, check out the documentation.

Pull requests for new language support welcome! Languages with built-in support: Python, JavaScript, CoffeeScript, Haskell, PureScript, Ruby, OCaml, R, Clojure/ClojureScript, PHP, Lua, C++, Julia, Elm, Elixir, TypeScript, Mathjs It's extensible to nearly any language that provides a REPL (interactive interpreter)! It opens a pane synchronized to your main buffer which displays the results of evaluating each line as you type (with NeoVim or Vim with +job and +channel, asynchronously). Using Codi as a Python scratchpad through the shell wrapperĬodi is an interactive scratchpad for hackers, with a similar interface to Numi.
