Simple Timing Model
Figure 4
shows the CoolRunner Timing Model. The Cool-
Runner timing model looks very much like a 22V10 timing
model in that there are three main timing parameters,
including t
PD
, t
SU
, and t
CO
. In other competing architec-
tures, the user may be able to fit the design into the CPLD,
but is not sure whether system timing requirements can be
met until after the design has been fit into the device. This
is because the timing models of competing architectures
are very complex and include such things as timing depen-
dencies on the number of parallel expanders borrowed,
sharable expanders, varying number of X and Y routing
channels used, etc. In the XPLA architecture, the user
knows up front whether the design will meet system timing
requirements. This is due to the simplicity of the timing
model.
