Macrocell Architecture
Figure 5 shows the architecture of the macrocell used in the
CoolRunner XPLA3 CPLD. Any macrocell can be reset or
preset on power-up. Each macrocell register can be config-
ured as a D-, T-, or Latch-type flip-flop, or bypassed if the
macrocell is required as a combinatorial logic function.
Each of these flip-flops can be clocked from any one of eight
sources or their complements. There are two global syn-
chronous clocks that are selected from the four external
clock pins. There is one universal clock signal. The clock
input signals CT[4:7] (Local Control Terms) can be individu-
ally configured as either a PRODUCT term or SUM term
equation created from the 40 signals available inside the
function block.
There are two muxed paths to the ZIA. One mux selects
from either the output of the VFM or the output of the regis-
ter. The other mux selects from the output of the register or
from the I/O pad of the macrocell. When the I/O pin is used
as an output, the output buffer is enabled, and the macrocell
feedback path can be used to feed back the logic imple-
mented in the macrocell. When an I/O pin is used as an
input, the output buffer is 3-stated and the input signal is fed
into the ZIA via the I/O feedback path. The logic imple-
