Xilinx produced the first commercially viable field-programmable gate array in 1985 [3] – the XC2064. [5] The XC2064 had programmable gates and programmable interconnects between gates, the beginnings of a new technology and market. [6] The XC2064 had 64 configurable logic blocks (CLBs), with two three-input lookup tables (LUTs). [7]
Field-programmable gate array prototyping (FPGA prototyping), also referred to as FPGA-based prototyping, ASIC prototyping or system-on-chip (SoC) prototyping, is the method to prototype system-on-chip and application-specific integrated circuit designs on FPGAs for hardware verification and early software development.
These computing platforms can follow either a purely spatial computing model, as in field-programmable gate array (FPGA), or a temporal computing model, where a function is evaluated across multiple clock cycles. The latter approach aims at reducing the overhead of programmable interconnect in FPGA by folding interconnect resources inside a ...

Place and route (also called PnR or P&R) is a stage in the design of printed circuit boards, integrated circuits, and field-programmable gate arrays.As implied by the name, it is composed of two steps, placement and routing.
Sinclair ZX81 ULA. A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory.
In computing, a logic block or configurable logic block (CLB) is a fundamental building block of field-programmable gate array (FPGA) technology. [citation needed] Logic blocks can be configured by the engineer to provide reconfigurable logic gates. [citation needed]
Field programmable gate arrays are often used as a support to partial reconfiguration. Electronic hardware, like software, can be designed modularly, by creating subcomponents and then higher-level components to instantiate them. In many cases it is useful to be able to swap out one or several of these subcomponents while the FPGA is still ...
