hwtLib.sim.abstractMemSpaceMaster module

class hwtLib.sim.abstractMemSpaceMaster.AbstractMemSpaceMaster(bus, registerMap)

Bases: MemorySpaceItemStruct

Abstraction over bus interface which converts it to memory space from where you can read or write

__init__(bus, registerMap)

_mask(start, width)

_read(addr, size, onDone=None)

Add read transaction to agent of interface :param addr: address value on bus to read froms :param size: size of data to read in bites :param onDone: on read done callback function(sim) -> None

_write(addr, size, data, mask, onDone=None)

Add write transaction to agent of interface

Parameters

• addr – address value on bus to write on

• size – size of data to write in bites

• data – data to write on bus

• onDone – on write done callback function(sim) -> None

parse_responses()

Parse responses after sim

class hwtLib.sim.abstractMemSpaceMaster.MemorySpaceItem(memHandler, transTmpl, offset=0)

Bases: object

Abstraction over place in memory, allows you read and write data to/from this space

__init__(memHandler, transTmpl, offset=0)

_add_read_resp(resp)

_add_write_resp(resp)

read(onDone=None)

read data from place in memory

write(data, onDone=None)

write data to place in memory

class hwtLib.sim.abstractMemSpaceMaster.MemorySpaceItemArr(memHandler, transTmpl, offset=0)

Bases: object

Abstraction over place in memory, allows you read and write data to/from this space

__getitem__(index)

class hwtLib.sim.abstractMemSpaceMaster.MemorySpaceItemStruct(memHandler, transTmpl, offset=0)

Bases: object

__init__(memHandler, transTmpl, offset=0)

_decorateWithRegisters(memHandler, structT)

Decorate this object with attributes from memory space (name is same as specified in register map)

Parameters

• memHandler – instance of AbstractMemSpaceMaster(subclass of)

• structT – instance of HStruct or TransTmpl used as template
