Assigning Cliques
You can define a group of logic functions as a single, named unit, called a clique. The MAX+PLUS® II Compiler attempts to place all logic in the clique in the same logic array block (LAB) to ensure optimum speed. If the project does not use multi-LAB devices, or if it is not possible to fit all clique members into a single LAB, the clique assignment ensures that all members of a clique are placed in the same device. In FLEX® 6000, FLEX 8000, FLEX 10K, and MAX® 9000 devices the Compiler also attempts to place the logic in LABs in the same row. Cliques therefore allow you to partition a project so that only a minimum number of signals travel between LABs, and to ensure that no unnecessary LAB-to-LAB or device-to-device delays exist on critical timing paths.

To assign a clique, use the following syntax:
