Detailed Description

template<typename axiCfg, int numReg, int numAddrBitsToInspect = axiCfg::addrWidth>
class AxiSlaveToReg< axiCfg, numReg, numAddrBitsToInspect >

An AXI slave containing memory-mapped registers.

Template Parameters

axiCfg	A valid AXI config.
numReg	The number of registers in the slave. Each register has a width equivalent to the AXI data width.
numAddrBitsToInspect	The number of address bits to inspect when determining which slave to direct traffic to. If this is less than the full address width, the routing determination will be made based on the number of address LSBs specified. (Default: axiCfg::addrWidth)

Overview

AxiSlaveToReg is an AXI slave that saves its state in a bank of registers. The register state is accessible as an array of sc_out.

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/AxiSlaveToReg/run/while -PIPELINE_STALL_MODE stall

This may reduce area/power.
