Constructor & Destructor Documentation

MemSegment()

MemSegment::MemSegment	(	etiss::uint64	start_addr,
		etiss::uint64	size,
		access_t	mode,
		const std::string	name,
		etiss::uint8 *	mem = nullptr,
		std::string	initString = "",
		bool	InitEleSet = false,
		uint64_t	randomRoot = 0
	)

Constructor of Memory Segment.

Parameters

start_addr	Start address of segment
size	Size in bytes
mode	Access Mode (R/W/X)
name	Segment name
mem	Pre-allocated Memory (not overwritten with initString)
initString	String for initialization with imple_mem_system.memseg_initelement_ value: hex_string with 0x... / string /random options
InitEleSet	Should self allocated MemSegment be initialized?
randomRoot	If initString==Random use this value as generator root
