Identifying the Sources of FPGA Instability
The EP4CGX150CF23C8N FPGA, part of Intel's Cyclone IV GX series, is widely appreciated for its cost-effectiveness and versatility in a range of applications. However, like all complex digital systems, it can sometimes exhibit instability under specific conditions. Such instability can manifest in unexpected behavior, including glitches, incorrect outputs, system crashes, or even complete hardware failure. Understanding the common causes and how to approach debugging them is crucial for any FPGA engineer.
