How to Debug Microcontrollers and FPGAs

+ Essential Benchtop Waveform and Function Generator

Create Arbitrary Debug Stimulus

Microcontroller and field-programmable gate array (FPGA) debug often requires more than fixed square waves or simple clock outputs. Arbitrary waveform capability is used to create custom pulse patterns, timing offsets, voltage transitions, and repeated signal segments that match interface behavior, control-line activity, or abnormal edge cases observed during development.

A waveform generator applies those custom inputs to the device under test while an oscilloscope or logic analyzer captures the resulting response. Dual-channel operation can align related signals, compare timing relationships, or apply synchronized trigger and stimulus patterns during debugging of digital and mixed-signal behavior.

Embedded Debug Waveform Solution

Debugging microcontroller and FPGA behavior requires a controllable stimulus source that can reproduce nonideal timing, custom transitions, repeated segments, and edge-case patterns. Keysight Essential benchtop waveform and function generators support this workflow by generating arbitrary waveforms that can be edited, replayed, and aligned to match the signal conditions under investigation. Dual-channel synchronized output helps when two related signals must be stimulated together, and arbitrary waveform capability makes it easier to move beyond fixed-function patterns during bench debug. This supports practical validation of digital behavior, timing relationships, interface response, and event-driven signal handling under repeatable test conditions.
