class CCLO_BFM

Class providing a bus-functional model (at HLS Stream level) of the ACCL CCLO kernel.

Connects to the emulator/simulator.

Public Functions

CCLO_BFM(unsigned int zmqport, unsigned int local_rank, unsigned int world_size, const std::vector<unsigned int> &krnl_dest, hlslib::Stream<command_word> &callreq, hlslib::Stream<command_word> &callack, hlslib::Stream<stream_word> &data_cclo2krnl, hlslib::Stream<stream_word> &data_krnl2cclo, int target_ctrl_stream = 2)

Construct a new CCLO_BFM object.

Parameters:

  • zmqport – Number of port which connects to the ACCL emulator/simulator

  • local_rank – ID of local rank

  • world_size – Total number of ranks

  • krnl_dest – A vector of CCLO data port destination IDs to which to subscribe

  • callreq – HLS Stream for call commands issued by HLS functions

  • callreq – HLS Stream for call responses to HLS functions

  • data_cclo2krnl – HLS Stream for data provided by the (emulated) CCLO to HLS functions

  • data_krnl2cclo – HLS Stream for data provided by the HLS functions to the (emulated) CCLO

  • target_ctrl_stream – Control stream to use inside emulator/simulator. Do not change.
