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 LA-ispMACH 4000V/Z automotive family is 4+1 (total
5) product terms. The software automatically considers the availability and distribution of product term clusters as it
ts 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 tim-
ing variability for increased performance.
The enhanced Logic Allocator of the LA-ispMACH 4000V/Z automotive family consists of the following blocks:
Product Term Allocator
Cluster Allocator
Wide Steering Logic
Figure 4 shows a macrocell slice of the Logic Allocator. There are 16 such slices in the GLB.
