发明名称 FPGA powerup to known functional state
摘要 A field programmable gate array (FPGA) device including a non-non-programming-based default power-on electronic configuration. The non-non-programming-based default power-on electronic configuration defines a default state to initial a first logic function. Upon power-up, the FPGA device would be enabled to enter the default state without having first to be configured via a conventional programming mode, thus saving precious processing time during power-up. Several embodiments are disclosed, such as a mask via circuit, an asynchronized set/reset circuit, an unbalanced latch circuit and a flush and scan circuit. A related method is also disclosed to reduce the memory size dedicated to the first logic function to facilitate further programming after power-up. In addition to time saving and further programming, the FPGA device can also allow partial or incremental programming to expand the full functionality to match customer's different needs.
