Detailed Description
template<typename axiCfg, int numControlReg, int numStatusReg, int numAddrBitsToInspect = axiCfg::addrWidth>
class AxiSubordinateToCSReg< axiCfg, numControlReg, numStatusReg, numAddrBitsToInspect >
class AxiSubordinateToCSReg< axiCfg, numControlReg, numStatusReg, numAddrBitsToInspect >
An AXI subordinate containing memory-mapped registers.
- Template Parameters
-
axiCfg A valid AXI config. numControlReg The number of control (local writable state) registers in the subordinate. Each register has a width equivalent to the AXI data width. numStatusReg The number of status (external read-only state) registers in the subordinate. Each register has a width equivalent to the AXI data width. numAddrBitsToInspect The number of address bits to inspect when determining which subordinate 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
- AxiSubordinateToCSnReg is an AXI subordinate that saves its state in a bank of registers. The register state is accessible as an array of sc_out. Access to read-only status registers is provided as an array of sc_in. The status register address range immediately follows the control (read/write) register address range
- 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/AxiSubordinateToCSReg/run/while -PIPELINE_STALL_MODE stall
