Figure 8. XC7336 Timing Model
Timing Model
Timing within the XC7336 is accurately determined using
external timing parameters from the device data sheet,
using a variety of CAE simulators, or with the timing
model shown in Figure 8.
Fast Function Block (FFB) Internal AC Characteristics
Notes: 5. Specifications account for logic paths that use the maximum number of available product terms for a given Macrocell.

The timing model is based on the fixed internal delays of
the XC7336 architecture which consists of three basic
parts: I/O Blocks, the UIM and Fast Function Blocks. The
timing model identifies the internal delay paths and their
relationships to ac characteristics. Using this model and
the ac characteristics, designers can easily calculate the
timing information for the XC7336.
