Detailed Description

template<typename Cfg, int ROBDepth = 8, int MaxInFlightTrans = 4>
class AxiManagerGate< Cfg, ROBDepth, MaxInFlightTrans >

An AXI manager that converts from a simple request/response interface to AXI with reordering support.

Template Parameters

Cfg	A valid AXI config.
ROBDepth	The depth of the reorder buffers.
MaxInFlightTrans	The number of independent AXI requests that can be in flight simultaneously.

Overview

This block takes as inputs RdRequest and WrRequest Connections. The block converts the requests into AXI format, sends them to AXI manager ports, and processes the responses into RdResponse and WrResponse ports. ReorderBuf and ReorderBufWBeats are used to allow reordering via use of the AXI ID field.

Usage Guidelines

This module sets the stall mode to flush by default to mitigate possible RTL bugs that can occur in the default stall mode. If you are confident that this class of bugs will not occur in your use case, you can change the stall mode via TCL directive:

directive set /path/to/AxiManagerGate/run_rd/while -PIPELINE_STALL_MODE stall

This may reduce area/power.
