SparseMemoryStorage class - rohd_hcl library

Constructors

SparseMemoryStorage({required int addrWidth, required int dataWidth, LogicValue alignAddress(LogicValue addr)?, LogicValue onInvalidRead(LogicValue addr, int dataWidth)?, void onInvalidWrite()? = _defaultOnInvalidWrite}): Constructs a new sparse memory storage with specified addrWidth for all addresses.

addresses → List<LogicValue>: A list of addresses which have data stored in this memory.
no setteroverride
addrWidth → int: The width of addresses.
finalinherited
alignAddress → LogicValue Function(LogicValue addr): A function to align addresses when used for transactions.
finalinherited
dataWidth → int: The width of data.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
isEmpty → bool: Returns true if there is no data stored in this memory.
no setteroverride
onInvalidRead → LogicValue Function(LogicValue addr, int dataWidth): A function called if a read is made to an address that has no data.
finalinherited
onInvalidWrite → void Function(): A function called if an invalid write is made when not isEmpty.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

dumpMemString({int radix = 16, int bitsPerAddress = 8}) → String: Dumps the contents of memory to a verilog-compliant hex file.
inherited
getData(LogicValue addr) → LogicValue?: Returns the data at addr, or null if it is not present.
override
invalidWrite() → void: Triggers behavior associated with an invalid write, including calling onInvalidWrite and resetting all of memory.
inherited
loadMemString(String memContents, {int radix = 16, int bitsPerAddress = 8}) → void: Reads a verilog-compliant mem file and preloads memory with it.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
readData(LogicValue addr) → LogicValue: Aligns the address with alignAddress, then returns either the getData result in storage or else onInvalidRead's result.
inherited
reset() → void: Resets all memory to initial state.
override
setData(LogicValue addr, LogicValue data) → void: Loads data into addr directly into storage.
override
toString() → String: A string representation of this object.
inherited
writeData(LogicValue addr, LogicValue data) → void: Performs some validation on a write, aligns the address with alignAddress, and then calls setData.
