ispMACH 4A TIMING MODEL
The primary focus of the ispMACH 4A timing model is to accurately represent the timing in a
ispMACH 4A 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 from feedback 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 ispMACH 4A
timing model is shown in Figure 15. Refer to the application note entitled MACH 4 Timing and
High Speed Design for a more detailed discussion about the timing parameters.
SPEEDLOCKING FOR GUARANTEED FIXED TIMING
The ispMACH 4A architecture allows allocation of up to 20 product terms to an individual
macrocell with the assistance of an XOR gate without incurring additional timing delays.
The design of the switch matrix and PAL blocks guarantee a xed pin-to-pin delay that is
independent of the logic required by the design. Other competitive CPLDs incur serious timing
delays as product terms expand beyond their typical 4 or 5 product term limits. Speed and
SpeedLocking combine to give designs easy access to the performance required in today’s
designs.
