In VHDL, std_logic is a data type. It is assigned to input and / or output variables. It means that the variable is a standard logic type i. e. a logic bit which accepts or provides one bit data, either 1 or 0.

What is the difference between the FTD and STD's?
FTD = Florists' Transworld Delivery. STD = Sexually Transmitted Disease.
Why use process statement in vhdl?
Almost all programming languages are sequential in nature. But VHDL is a concurrent language. In an architecture for an entity, all statements are concurrent. So where do sequential statements exist in VHDL?. There is a statement called the process statement that contains only sequential statements. The process statement is itself a concurrent statement. A process statement can exist in an architecture and define regions in the architecture where all statements are sequential. A process statement has a declaration section and a statement part. In the declaration section, types, variables, constants, subprograms, and so on can be declared. The statement part contains only sequential statements. Sequential statements consist of CASE statements, IF THEN ELSE statements, LOOP statements, and so on.
What is an inference similar to?
An inference is a conclusion reached by logic, but it is also used to mean a guess which is loosely based on logic. Similar ideas are: speculation, conclusion, guess, "guesstimate," induction, supposition.
The z score for 78?
For z-score calculation, mean and std deviation must be given.
If you got a std from my boyfriend does that mean his cheating on me?
sexually transmited dissease! umm...probablly!..but..who knows! :)
What is the Difference between verilog and vhdl language?
C is a high level language that is compiled into machine language for specific system. The system implements some sort of state machine that can process the compiled machine language. In VHDL you have to design the statemachine itself. Furthermore VHDL is compiled into logic primitives that could be built by logic gates which itself could be realized with transistors. C is a programming language. VHDL is a hardware description language.
What is meant by an architecture in VHDL programming?
While implementing a system in VHDL, we consider two major aspects. One is the external view of the system and the other is the internal view. To represent these two, we have entity and architecture in VHDL programming. Hence, architecture in VHDL provides the internal structure (or functioning or logic) of the system to be designed.
Why 1164 used in encoder vhdl programming?
VHDL program follows IEEE library. This means that all the data types, commands, keywords etc. used in a VHDL program are stored in a library called IEEE library. This library will be available in the EDA tool which is executing the VHDL program. 1164 is a package where all the logic gates are defined. This is a sub part of IEEE library. As encoder program requires logic gates, we need to use 1164 package in the code.
What does the acronym VHDL stand for?
The acronym VHDL can have several different meanings depending on the subject you are discussing. Some of these meanings include; Very High Density Logic,Virtual Hardware Description Language and Very High Density Lipoprotein.
Full form of vhdl?
There is not any fullform of verilog.Infact the whole word is called "Verilog HDL" which is "Verilog Hardware Description Language".
What is VHDL calculators?
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.

Is VHDL text or graphic programmed?
VHDL is a text based programming language.
What is synthesis in VHDL?
A VHDL program is written to realize an electronic circuit, system or design. After simulating the code, one needs to dump it into an FPGA or CPLD. This programmable logic device, after dumping, act like the designed system. The inter connections of these devices need to be made as per the code. This means that that a program code which might be logic based now needs to be converted into a physically realizable structure. This involves building a physical structure within an FPGA or CPLD. This process involves converting the VHDL code into a format that can be understood by FPGA or CPLD. Converting our code into 1s and 0s that suit the FPGA or CPLD structure is called synthesis.
