10、he cognizance of 32-44.1 Committee on Gate Arrays.) I 1.0 SCOPE 1.1 INTRODUCTION This JEDEC Standard defines a minimum set of macrocell standards for CMOS gate arrays. A total of 41 macrocell types are addressed, all of which are commonly used by gate array designers to implement Application Specifi
11、c Integrated Circuits. The logic types covered include: NAND NOR XOR/XNOR INVERTERS MULTIPLEXER 1/0 INTERFACE LATCHES FLIP FLOPS AND/OR/INVERT 1.2 RATIONALE With the advent of Computer Aided Design Tools on minicomputers and workstations, a number of gate array users are now doing logic netlist defi
12、nition and functional simulation on inhouse machines in order to optimize development time and costs. Once a correct functional simulation is obtained, the user is then ready ta transfer his design to a specific gate array vendor. However, unless come minimum set of commonly accepted macrocells exis
13、ts in the industry, it is entirely possible that the user may configure his logic in cells that may not be directly translatable to cells in the vendors library. As such, duplication of efforts and extra time spent on transferring a specific design to a vendor often happens, which affects the final
14、cost to the user, Alternatively, a user may want to configure his logic in advance of choosing a vendor and yet be able to map his logic over to several vendors libraries of cells with minimum difficulty. While CAD standards efforts such as EDIF address issues of translation of netlists between unli
15、ke CAD systems, they do not cover standard macrocell types. Hence, this Standard is meant to facilitate easy netlist transfer between vendors and users. .

18、 information directly from his vendor of choice at the time of design implementation. Vendar A 1.4 NAMING CONVENTIONS: Naming conventions are always a subject of high concern among semicustom XC designers. The following convention has been used successfully by several companies and is known to work
19、in the semicustom IC marketplace. macrocell standards is JXXXXXXn where the following rules were used in arriving at this convention: - Up to 8 fields may be used to define a macrocell name. name length will be kept to the minimum required to adequately name the macrocell. - The first character used
20、 will be a J to denote a JEDEC macrocell. The basic format for naming the The 7 EIA JESDL2-3 86 = 3234600 0004842 2 JEDEC Standard No. 12-3 Page 3 - The next letters (up to six) will be used to describe the type of macrocell. Experience has shown us that logic designers prefer names that are somewha
21、t descriptive of the logic type. Since this standard deals with a limited number of macrocell types, it makes such a convention possible. Thus, for example: ND = NR = xo = IV = AO1 = BI = BTB = BIS = BIT = BIC = BO = BTO = Mx= LD = LDR = LDS = FJKR = FDSR = FDR = FDS = FJKS = PSS = PDD = NAND NOR EX
