◆ access_batch()

EAccessBatchResult isys::CSoCCtrl::access_batch ( CAccessBatch & rAccessBatch )

Performs a batch memory access operation.

Parameters

rAccessBatch Reference to access batch structure containing the details of the batch operation. The data can be received by calling CAccessBatch::item(...) and reading from it's data member.

Returns: EAccessBatchResult Result of the access batch operation.

Exceptions

TException if the operation fails.

Python example: test_soc_ctrl_bus_access_batch.py

result = soc.access_batch(access_batch)

◆ attach()

void isys::CSoCCtrl::attach ( )

Python example: test_soc_ctrl_attach.py

>>> conn_mgr = ic.ConnectionMgr()
>>> conn_mgr.connect()
>>> sess_ctrl = ic.CSessionCtrl(conn_mgr)

Fills a memory region with a specified pattern via the specified bus.

Parameters

nBusIndex	Index of the bus to use.
nAddress	Address to start writing the pattern.
nNumMAUs	Number of Memory Access Units (MAUs) to write.
rvPattern	Pattern to fill the memory with. If shorter than nNumMAUs, the pattern repeats.

Exceptions

TException if the operation fails.

Python example: test_soc_ctrl_bus_fill.py

>>> conn_mgr = ic.ConnectionMgr()
>>> conn_mgr.connect()
>>> vect = ic.VectorBYTE([1, 2, 3, 4])
>>> sess_ctrl = ic.CSessionCtrl(conn_mgr)
>>> sess_ctrl.begin_reset()
>>> soc = sess_ctrl.get_SoC('')
>>> soc.bus_fill(0, 0x20000000, 4, vect)
>>> vect_read = soc.bus_read(0, 0x20000000, 4)
>>> [e for e in vect_read]
[1, 2, 3, 4]

◆ bus_read()

std::vector< uint8_t > isys::CSoCCtrl::bus_read	(	uint8_t	nBusIndex,
		uint64_t	nAddress,

		std::vector< uint8_t > *	pvAccess = nullptr )

Reads data from memory via the specified bus.

Parameters

nBusIndex	Index of the bus to use.
nAddress	Address to read from.
nNumMAUs	Number of MAUs to read.
