Review the NCO_1MHz MegaCore Function Instance
To review the parameters for the NCO_1MHz MegaCore function, follow
these steps:
1. Double-click the NCO_1MHz block (see Figure 4) to launch IP
Toolbench for the NCO Compiler MegaCore function, as shown in
Figure 5.

2. Click Step 1: Parameterize to review the parameters for the
NCO_1MHz block (see Figure 6 and Figure 7 on page 10). The
NCO_1MHz block generates a 1-MHz sinusoidal signal and is
implemented using the multiplier-based architecture, which
reduces memory usage by using the hardware multipliers in the
Stratix II device.
