Agilent Technologies 16760A manual Search Pattern, Offset By Option

Chapter 5: Reference

The Symbols Tab

	Offset By	Lets you add an offset value to the starting point of a
		symbol. This can be useful when compensating for
		microprocessor prefetches (see “Offset By Option” on
		page 196).
	Align to	Lets you mask the lower order bits of a symbol's value. This
		can be useful for triggering on odd byte boundaries (see
		“Align to x Byte Option” on page 197).
	Beginning/End/
	Range	When a symbol represents a range of addresses, you can
		choose the beginning address of the range, the end address
		of the range, or the whole range.

Search Pattern

Use this field to locate particular symbols in the symbol databases. To use this field, enter the name of a file or symbol. The system searches the symbol database for symbols that match this name. Symbols that match appear in the list of Matching Symbols. You can also use wildcard characters to find symbols.

Asterisk wildcard (*) The asterisk wildcard represents "any characters." When you perform a search on the symbol database using just the asterisk, you will see a list of all symbols contained in the database. The asterisk can also be added to a search word to find all symbols that begin or end with the same letters. For example, to find all of the symbols that begin with the letters "st", select the Search Pattern field and enter "st*".

	Offset By Option
	The Offset By option allows you to add an offset value to the starting
	point of the symbol that you want to use. You might do this in order to
	trigger on a point in a function that is beyond the preamble of the
	function, or to trigger on a point that is past the prefetch depth of the
	processor. Setting an offset helps to avoid false triggers in these
	situations. The offset specified in the Offset By field is applied before
	the address masking is done by the "Align to x Byte" option.
Example	An 80386 processor has a prefetch depth of 16 bytes. Assume functions
