1 Reasons Driving Change in FPGA Debugging Technology The reprogramming capability of FPGAs is a key advantage in the functional debugging of hardware designs. In the early days of using CPLDs and FPGAs, when a design was found to be malfunctioning, engineers would use the “debug hook” method. They would route the internal signals of … Read more
PROFIBUS is an international, open, fieldbus standard that is independent of device manufacturers. The transmission speed can be selected from 9.6 kbaud to 12 Mbaud, and when the bus system starts, all devices connected to the bus should be set to the same speed. It is used for factory automation at the workshop level for … Read more
