Mark the statements concerning Standard Cells which are true. FPGAS have better performances, in terms of speed and consumption, than Standard Cells. Gate Arrays have better performances, in terms of integration density, speed and consumption, than Standard Cells. In the Standard Cell approach, library cells are places in rows separated by routing channels. In some cases, cells cover the silicon surface completely and interconnection layers pass over them. Standard Cells use a library of cells where the layout of all cells has the same height and the same width. O Macrocells are special library cells that implement, in general, more complex functions than logic gates or bistables. In many cases, libraries contain configurable macrocells such that the designer can define some of their parameters (for instance, number of words and bit/word of a memory block, length of a shift register, etc.). Macrocells are special library cells such that the designer can define their height and width. 4.
