32 / 70 page  000-0046108-108 Page 31 of 69 SLG46108 10.0 Combination Function Macrocells The SLG46108 has seven combination function macrocells that can serve more than one logic or timing function. In six of these cases, they can serve as a Look Up Table (LUT), or as another logic or timing function. In the last case, it can serve as either a programmable delay or deglitch filter. See the list below for the functions that can be implemented in these macrocells: • Two macrocells that can serve as either 2-bit LUTs or as DFF/Latch; • Two macrocells that can serve as either 3-bit LUTs or as DFF/Latch; • One macrocell that can serve as either 3-bit LUT or as Pipe Delay; • One macrocells that can serve as either 4-bit LUTs or as 8-Bit Counter/Delay; • One macrocell that can serve as either a Programmable Delay or as a Deglitch Filter. Inputs/Outputs for the seven combination function macrocells are configured from the connection matrix with specific logic func- tions being defined by the state of NVM bits. 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). When used as a D Flip Flop/Latch, the source and destination of the inputs and outputs for the DFF/Latches are configured from the connection matrix. All DFF/Latch macrocells have user selection for initial state, and all have the option to connect both the Q and nQ outputs to the connection matrix. The macrocells DFF2, DFF3 have an additional input from the matrix that can serve as a nSet or nReset function to the macrocell. The operation of the D Flip-Flop and Latch will follow the functional descriptions below: DFF: CLK is rising edge triggered, then Q = D; otherwise Q will not change Latch: if CLK = 1, then Q latches D value 10.1 2-Bit LUT or D Flip Flop Macrocells There are two macrocells that can serve as either 2-bit LUTs or as D Flip Flops. When used to implement LUT functions, the 2-bit LUTs each take in two input signals from the connection matrix and produce a single output, which goes back into the connection matrix. When used to implement D Flip Flop function, the two input signals from the connection matrix go to the data (D) and clock (CLK) inputs for the Flip Flop, with the output going back to the connection matrix. |
