An apparatus and method for implementing synchronous triggers for waveform capture in a multiple FPGA system is described. The apparatus includes trigger net circuitry that has one or more trigger nets and an output. Furthermore, a plurality of programmable logic devices are provided with each logic device including logic circuitry that is programmable to correspond to a circuit design, a logic analyzer circuit that includes logic connections coupled to the logic circuitry to monitor operating signals of the circuit design, and a register with a data input that is coupled to the output of the trigger net circuitry and an output that is coupled to a control input of the logic analyzer circuit. The trigger net circuitry outputs a control signal that is applied to all registers such that each logic analyzer circuit is controlled to concurrently capture data waveforms.
