Detect Illegal Memory AccessesRequirement: Detect illegal accesses that fail in Hardware

MAP command allows to define access rights: read, write, executeOn illegal memory access you may display messages or stop simulation

// Un-aligned memory access create wrong values in Hardware// but are hard to detect during JTAG Debugging

typedef struct { struct {

COLOR Color; INPUT_EVENT Event;

unsigned short Level; unsigned char Buffer[10];

} LEVEL; } Input;

unsigned short SetStruct (void) {

LEVEL *pLevel;

pLevel = (LEVEL *)&Input.Buffer[0]; // set pointer

pLevel->Level = 0x1234; // UN-ALIGN ACCESS!
