MemoryStorage class - rohd_hcl library

Constructors

MemoryStorage({required int addrWidth, required int dataWidth, void onInvalidWrite()? = _defaultOnInvalidWrite, LogicValue onInvalidRead(LogicValue addr, int dataWidth)?, LogicValue alignAddress(LogicValue addr)?}): Constrcuts a MemoryStorage with specified addrWidth and dataWidth.

addresses → List<LogicValue>: A list of addresses which have data stored in this memory.
no setter
addrWidth → int: The width of addresses.
final
alignAddress → LogicValue Function(LogicValue addr): A function to align addresses when used for transactions.
final
dataWidth → int: The width of data.
final
hashCode → int: The hash code for this object.
no setterinherited
isEmpty → bool: Returns true if there is no data stored in this memory.
no setter
onInvalidRead → LogicValue Function(LogicValue addr, int dataWidth): A function called if a read is made to an address that has no data.
final
onInvalidWrite → void Function(): A function called if an invalid write is made when not isEmpty.
final
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.
getData(LogicValue addr) → LogicValue?: Returns the data at addr, or null if it is not present.
invalidWrite() → void: Triggers behavior associated with an invalid write, including calling onInvalidWrite and resetting all of memory.
loadMemString(String memContents, {int radix = 16, int bitsPerAddress = 8}) → void: Reads a verilog-compliant mem file and preloads memory with it.
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.
reset() → void: Resets all memory to initial state.
setData(LogicValue addr, LogicValue data) → void: Loads data into addr directly into storage.
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.
