Abstract: Various approaches for tracing events in an electronic system are disclosed. In one approach, a circuit arrangement includes a bus, a random access memory (RAM), a plurality of programmable logic resources, and coupled configuration memory cells. A circuit arrangement is implemented in the programmable logic. The circuit arrangement receives a plurality of event indication signals from an application circuit and writes event data to the RAM in response to a change in the state of any one of the event indication signals. A bus interface circuit is coupled to the bus and to the read port of the RAM. Responsive to a read transaction on the bus for the RAM, the bus interface circuit reads data from the RAM and outputs the data on the bus in a reply bus transaction.
