These values are specified under the recommended operating conditions shown in
Figure 12
These values are specified for a PIA fan-out of one LAB (16 macrocells). For each additional LAB fan-out in these
devices, add an additional 0.1 ns to the PIA timing value.
This minimum pulse width for preset and clear applies for both global clear and array controls. The t
must be added to this minimum width if the clear or reset signal incorporates the t
path.
This parameter is measured with a 16-bit loadable, enabled, up/down counter programmed into each LAB.

Supply power (P) versus frequency (f
devices is calculated with the following equation:
P = P
The P
