ABSTRACT:
Systems and methods utilizing virtual input/output (VIO) modules in PLDS. One or more VIO modules are embedded in a PLD along with the user circuit to be controlled and monitored. The VIO module includes a control module that acts as a virtual input module for the user circuit, and can optionally include a status module that acts as a virtual output module for the user circuit. A bi-directional data interface is provided between the user circuit and the VIO modules, and between the VIO modules and a communication module. The communication module is coupled through input/output pads of the PLD to an external communication link, and hence to a host computer in which resides software that controls the communication link. Thus, by interfacing with the host computer, a user can control the user circuit via the control modules and monitor output signals from the user circuit via the status modules.
