clock and also selects the probes to be monitored. The

simulator will then clock through the specified number of

clock cycles and display the resulting time domain response.

Figure 5 shows a typical probe display.

Monarch 2.0 DSP Design Software

DECIMATE is fully integrated with Monarch 2.0 professional

DSP design software. Monarch is a full featured DSP

package with FIR lIR filter design and analysis, two

dimensional and three dimensional viewing, a

programmable signal/systems laboratory with 100 +

DSP/Math functions, extensive fixed-point support and

FFTs/IFETs Monarch is available separately from The

Athena Group, Inc.

When used with Monarch 2.0, DECIMATE becomes a full

feature design environment for a DSP system. Data can

easily be transferred from DECIMATE modules to the

Monarch modules for further analysis.
