A user logic design for a mask-programmable logic device ('MPLD') may be designed on a comparable or compatible user-programmable logic device ('UPLD') and migrated to the MPLD, or may be designed directly on an MPLD. If the design is designed on a UPLD, the constraints of the target MPLD&#x2014;i.e., differences between the devices&#x2014;are taken into account so that the migration will be successful. If the design is designed directly on an MPLD, constraints of a comparable compatible UPLD are taken into account if the user indicates that the design will be migrated to the UPLD for testing. This means that when a logic design is intended to be migrated back-and-forth between a UPLD and an MPLD, only the intersection of features can be used. To facilitate migration, fixed mappings between pairs of devices may be created.

Method for programming a mask-programmable logic device and device so programmed

A reconfigurable programmable logic system including a programmable logic device and an associated processor is configured using a configuration file including (a) instructions for configuring the programmable logic device as one or more peripherals to be used by the processor, and (b) a list of the peripherals to be configured in the programmable logic. The processor uses the peripheral data from the configuration file to load the appropriate drivers, create all necessary instances of the drivers and optionally to pass parameters for any necessary initial command after each driver is loaded. Optionally, each time the system is configured, any previously loaded drivers are first unloaded.
