The ability to update the functionality after shipping, partial re- configuration of a portion of the design. FPGAs can be used to implement any logical function that an ASIC could perform. ![]() Floor planning enables resource allocation within FPGAs to meet these time constraints. As FPGA designs employ very fast I/Os and bidirectional data buses, it becomes a challenge to verify correct timing of valid data within setup time and hold time. In most FPGAs, logic blocks also include memory elements, which may be simple flip- flops or more complete blocks of memory. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application- specific integrated circuit (ASIC). A field- programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence. Field- programmable gate array - Wikipedia.
