7.1.2. Local Threshold

This design example has two identical NCOs—one is in a subsystem with a LocalThreshold block that is set to force soft rather than hard multipliers.

After simulation, in the resource table, you can compare the resources for NCO and NCO1. NCO1 uses no multipliers at the expense of extra logic. The resource table also contains resources for the ChannelViewer blocks—synthesizable blocks, that the design example uses outside the device system.

The model file is demo_nco_threshold.mdl.
