//
|
|
// Description:
|
|
//
|
|
// RFNoC data record and playback block. This block has the ability to
|
|
// capture all of the data that is sent to it and store it into an attached
|
|
// memory using an AXI memory-mapped interface. It can then play back any
|
|
// part of the data on demand or continuously. Timed playback is also
|
|
// supported. See axis_replay.v for details of replay operation.
|
|
//
|
|
// Parameters:
|
|
//
|
|
// THIS_PORTID : Control crossbar port to which this block is connected
|
|
// CHDR_W : AXIS-CHDR data bus width
|
|
// MTU : Maximum transmission unit (i.e., maximum packet size in
|
|
// CHDR words is 2**MTU).
|
|
// NUM_PORTS : Number of replay instances to instantiate. Each one will
|
|
// have its own register set and memory interface.
|
|
// MEM_DATA_W : Data width to use for the memory interface.
|
|
// MEM_ADDR_W : Byte address width to use for the memory interface.
|
|
//
