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.
Properties
- 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.

Methods
-
getData(
LogicValue addr) → LogicValue? -
Returns the data at
addr, ornullif it is not present.override -
invalidWrite(
) → void -
Triggers behavior associated with an invalid write, including calling
onInvalidWrite and resetting all of memory.
inherited
-
loadMemHex(
String hexMemContents) → void -
Reads a verilog-compliant hex 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
dataintoaddrdirectly 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.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
