Deductive reasoning is a mental process where a VHDL is compiled and mapped into AN implementation technology so much as an Field-programmable gate arrayA field-programmable gate array (FPGA) is an amalgamated circuit designed to be configured away a customer surgery a designer aft manufacturing – thu the term "field-programmable". The FPGA constellation is generally nominative using a computer hardware description language (HDL), similar to that used for a… or an ASIC. Not all constructs in VHDL ar suitable for deductive reasoning. For example, well-nig constructs that expressly deal with timing such as delay for 10 ns; are not synthesizable despite being sound for simulation.First appeared: 1980sParadigm: , , Stable release: IEEE 1076-2019, / 23 December 2019; 21 months agoTyping discipline:

Can a VHDL synthesis tool be too far away?
A synthesis tool infers the logic it synthesizes from the context in which specific constructs appear in a design description. If the VHDL code is physically meaningless or too far removed from the hardware it attempts to describe, it may not be synthesizable.

What is the definition of synthesis in VHDL?
Synthesis is a process in which a physical system is constructed from an abstract description using a pre-defined set of basic building blocks (e.g. logic gates, flip-flops, latches, small blocks of memory, LUTs in FPGA). Synthesis is the process of constructing a gate-level netlist from a model of a circuit described in VHDL.
Can a FPGA be used for VHDL synthesis?
In CS120b we will be writing VHDL code to be synthesized and mapped down to a Xilinx Spartan2 FPGA. Sometime in this class you will write a piece of code that will simulate correctly, but when you download to an FPGA things will go wrong.
