The following table shows the slice carry-chain timing parameters for a majority of the paths in Figure 1.

| Propagation Delays for Slice Configured as a Carry Chain | ||
|
TAXA/TAXB/TAXC/TAXD/ TBXB/TBXC/TBXD/ TCXC/TCXD/ TDXD |
AX/BX/CX/DX inputs to AMUX/BMUX/ CMUX/DMUX outputs | Propagation delay from the AX/BX/CX/DX inputs of the slice through the carry logic to the AMUX/BMUX/CMUX/DMUX outputs of the slice. |
| TAXCY/TBXCY/TCXCY/TDXCY | AX/BX/CX/DX inputs to COUT output | Propagation delay from the AX/BX/CX/DX inputs of the slice to the COUT output of the slice. |
| TBYP | CIN input to COUT output | Propagation delay from the CIN input of the slice to the COUT output of the slice. |
| TOPCYA/TOPCYB/TOPCYC/ TOPCYD | A/B/C/D inputs to COUT output | Propagation delay from the A/B/C/D LUT inputs of the slice to the COUT output of the slice. |
| TCINA/TCINB/TCINC/TCIND | CIN input to AMUX/BMUX/ CMUX/DMUX outputs | Propagation delay from the CIN input of the slice to AMUX/BMUX/CMUX/DMUX outputs of the slice using XOR (sum). |
| Setup and Hold Times for a Slice Configured as a Carry Chain(1) | ||
| TCINCK/TCKCIN | CIN input | Time before/after the CLK that the CIN input of the slice must be stable. |
