Abstract
During compilation of a user logic design in a first type of programmable logic device (e.g., an FPGA), a log is kept of at least certain steps where choices are made. When that logic design is migrated to another type of programmable logic device (e.g., a mask-programmable logic device) the logged steps are taken into account to make sure that the same choices are made, so that the target device is functionally equivalent to the original device.
