Detailed Description

template<typename axiCfg, typename rvCfg>
class AxiSubordinateToReadyValid< axiCfg, rvCfg >

An AXI subordinate that converts AXI requests into a simplified format.

Template Parameters

axiCfg	A valid AXI config.
rvCfg	A config for the ready-valid interface that is the output of the subordinate. The data and strobe fields are assumed to match the widths of their AXI counterparts.

Overview

This block converts AXI read and write requests into a simplified format consisting of a single ready-valid interface that has address, data, and write strobe fields, as well as a read/write indicator. Read responses are returned to the block via a second ready-valid interface (there are no write responses expected). AxiSubordinateToReadyValid handles all of the AXI-specific protocol, generating write responses and packing/unpacking bursts as necessary.

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/AxiSubordinateToReadyValid/run/while -PIPELINE_STALL_MODE stall

This may reduce area/power.
