Enhanced Logic Allocator
Within the logic allocator, product terms are allocated to macrocells in product term clusters. Each product term
cluster is associated with a macrocell. The cluster size for the ispMACH 4000 family is 4+1 (total 5) product terms.
The software automatically considers the availability and distribution of product term clusters as it fits the functions
within a GLB. The logic allocator is designed to provide three speed paths: 5-PT fast bypass path, 20-PT Speed
Locking path and an up to 80-PT path. The availability of these three paths lets designers trade timing variability for
increased performance.
The enhanced Logic Allocator of the ispMACH 4000 family consists of the following blocks:
Figure 4 shows a macrocell slice of the Logic Allocator. There are 16 such slices in the GLB.
