89 / 170 page 000-0046140-109 Page 88 of 169 SLG46140 12.5 4-bit LUT or Programmable Pattern Generator (PGEN) The SLG46140 has one combination function macrocell that can serve as a logic or timing function. This macrocell can serve as a Look Up Table (LUT), or Programmable Pattern Generator (PGEN). When used to implement LUT functions, the 4-bit LUT takes in four input signals from the connection matrix 0 and produce a single output, which goes back into the connection matrix 0. When used as a LUT to implement combinatorial logic functions, the outputs of the LUTs can be configured to any user defined function, including the following standard digital logic devices (AND, NAND, OR, NOR, XOR, XNOR). The user can also define the combinatorial relationship between inputs and outputs to be any selectable function. When operating as a Programmable Pattern Generator, the output of the macrocell with clock out a sequence of two to sixteen bits that are user selectable in their bit values, and user selectable in the number of bits (up to sixteen) that are output before the pattern repeats.See Figure 47.
