An architecture disposed in an integrated circuit for in-application programming of flash-based programmable logic devices includes a processor coupled to a processor system bus. An I/O peripheral is coupled to the processor over the system bus and is also coupled to an off-chip data source. A programmable logic device fabric includes flash-based programmable devices. A program controller is coupled to the flash-based programmable devices. An in-application programming controller is coupled to the program controller and is coupled to the processor over the system bus.

Apparatus and methods for in-application programming of flash-based programmable logic devices

Apparatus and methods for in-application programming of flash-based programable logic devices

A method for performing on-chip spatial debugging of a user circuit programmed into a user-programmable integrated circuit includes halting an internal clock driving synchronous logic elements in the integrated circuit and reading the states of all synchronous logic elements programmed into the integrated circuit while the internal clock is halted. An interrupt to an embedded processor in the integrated circuit running a user application can also be generated. The output of at least one synchronous logic element can be forced to a desired state while the internal clock is halted. The clock can then be restarted or stepped.
