This Technical Report gives recommendations, mainly to designers and manufacturers of integrated circuits, in order to arrive at symbols for devices with a consistent use of mnemonics and qualifying symbols. It is intended to serve two purposes, namely: - for white-box symbols, it gives a review of standardized designations; - for gray-box symbols, it is intended to limit the range of possible variations. White-box symbols are symbols in which the functional behaviour of an element is fully described by standardized means; the relevant rules and explanations are to be found in IEC 60617 in the application notes associated with the symbols S01463 S01730 (A00269 A00315) for binary logic elements, and with the symbols S01748 S01806 (A00281, A00296, A00321 A00330) for analogue elements. Gray-box symbols are symbols in which the functional behaviour of an element, mostly because of its complexity, is (partly) described by other means than those used for white-box symbols, particularly by referring to supporting documentation; the relevant rules and explanations are to be found in IEC 60617 in the application notes associated with the symbols S01731 S01747 (A00317 A00319). Where in the following tables the letter W is shown in the second column, this means that the designation concerned may be used in white-box symbols, as well as in gray-box symbols. A letter G in the second column means that the designation concerned may only be used in graybox symbols, or in white-box symbols between square brackets (e.g. [PDN] as additional information for "power down"). In these tables, the English descriptions appear in the third column and the French in the fourth, because in many cases designations are derived from terms in English. Where the letter m is used, it shall be replaced by the relevant value, identifying number, cycle length, number of bits or sequential number, as each case demands (with the exception of Am for gain adjust). Where m1 m2 is shown, m1 shall be replaced by the number of words and m2 by the number of bits per word. See symbols S01706 S01722.
