ADVANCE INFORMATION
When used to implement LUT functions, the 3-bit LUT takes in three input signals from the connection mux and produces a single output, which goes back into the connection mux.
These LUTs can be configured to any 3-input user defined function, including the following standard digital logic functions: AND, NAND, OR, NOR, XOR, XNOR, INV.
Table 7-3 provides the truth tables for a 3-bit LUT.
IN2 | IN1 | IN0 | OUT |
---|---|---|---|
0 | 0 | 0 | User defined |
0 | 0 | 1 | |
0 | 1 | 0 | |
0 | 1 | 1 | |
1 | 0 | 0 | |
1 | 0 | 1 | |
1 | 1 | 0 | |
1 | 1 | 1 |
Each 3-bit LUT has 8 bits in the OTP to define their output function.
