Detailed Description

template<typename axiCfg, int capacity, int fifoDepth = 8>
class AxiSlaveToMem< axiCfg, capacity, fifoDepth >

An AXI slave SRAM.

Template Parameters

axiCfg	A valid AXI config.
capacity	The capacity in bytes of the local SRAM.
fifoDepth	Depth of the input and output FIFO queues.

Overview

AxiSlaveToMem is an AXI slave with an internal dual-ported memory used for storage. The module only handles AXI addresses within the range of its internal memory, with a base address of 0. It does not support write strobes. It has internal queues to handle multiple simultaneous requests in flight, and can handle read and write requests independently, but it does not reorder requests.

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/AxiSlaveToMem/run/while -PIPELINE_STALL_MODE stall

This may reduce area/power.
