VLSI Implementation Media
Media requiring fabrication:
* Full Custom - design and physical layout at transistor level* Standard Cell - design and physical layout at gate/flip-flop level
* Gate Array - design and physical layout at gate level (like standard cell but with some prefabrication of wafer)
Prefabricated media:
* Field Programmable Gate Arrays (FPGAs) - design at gate/flip-flop or register transfer level
* Complex Programmable Logic Devices (CPLDs) - design at gate/flip-flop or register transfer level
* Programmable Logic Devices (PLDs) - design at gate/flip-flop level
* System-on-Chip (SoC) may incorporate several of these implementation media on a single chip
