MACH 5 TIMING MODEL
The primary focus of the MACH 5 timing model is to accurately represent the timing in a MACH 5
device, and at the same time, be easy to understand. This model accurately describes all
combinatorial and registered paths through the device, making a distinction between
internal
feedback and external feedback. A signal uses internal feedback when it is fed back into the switch
matrix or block without having to go through the output buffer. The input register specications
are also reported as internal feedback. When a signal is fed back into the switch matrix after having
gone through the output buffer, it is using external feedback.
The parameter, tBUF, is dened as the time it takes to go through the output buffer to the I/O pad.
If a signal goes to the internal feedback rather than to the I/O pad, the parameter designator is
followed by an “i”. By adding tBUF to this internal parameter, the external parameter is derived.
For example, tPD = tPDi + tBUF. A diagram representing the modularized MACH 5 timing model is
shown in Figure 7. Refer to the Technical Note entitled MACH 5 Timing and High Speed Design
for a more detailed discussion about the timing parameters.
