Chapter 4: Analysis & Synthesis Assignments 4–117<br />

MAX_LABS<br />

MAX_LABS<br />

Type<br />

Allows you to specify the maximum number of LABs that Analysis & Synthesis may<br />

use for a device. This option overrides the usual method of using the maximum<br />

number of LABs the current device supports, when the value is non-negative and is<br />

less than the maximum number of LABs available on the current device.<br />

This option is ignored when the value is greater than the maximum number of LABs<br />

available on the current device.<br />

You can use this option in incremental compilation to set different lab usage limits for<br />

different partitions.<br />

You can use this option as a project-wide option or on a specific partition by setting<br />

the assignment on the instance name of the partition root. The assignment on a<br />

partition overrides the global assignment, if any, for that particular partition.<br />

You can use this option for device migration.<br />

Integer<br />

Device Support<br />

This setting can be used in projects targeting any <strong>Altera</strong> device family.<br />
