IEEE defines both Verilog and VHDL as industry standards. Here’s a simple example of an AND gate in both languages. An AND gate has two inputs and one output. If the inputs are both equal to 1, the output is 1. If they are not equal or if both are set to 0, the output is...
In the world of FPGA design, understanding the components is crucial. Let’s dive into the intricate elements that make up an FPGA and how they contribute to its functionality. First and foremost, we have the programmable logic blocks (PLBs). These are like the brain cells of the FPGA, ...
In object-oriented programming (OOP), anobjectis essentially an instance of aclass. In OOP languages, a class is like a blueprint wherevariablesand methods are defined, and each time a new instance of the class (instantiation) is created, an object gets created -- hence the term object-or...
Types of EDA Tools Simulation Simulation tools take a description of a proposed circuit and predict its behavior before is it implemented. This description is typically presented in a standard hardware description language such as Verilog or VHDL. Simulation tools model the behavior of circuit ...
Most IP cores are developed using hardware description languages (HDLs), like VHSIC HDL, Verilog or SystemVerilog. An HDL is analogous to a computersoftwareprogram. A high-level specification language, likeC, can also be used to develop an IP core. ...
their data type specifications to quickly explore design tradeoffs. Using Fixed-Point Designer with MathWorks®code generation products, you can generate pure integer C code or bit-true Verilog®and VHDL®code from your fixed-point design. There are also cycle-true HDL optimized blocks ...
While the highest performance is typically provided by an SoC, this route is expensive and time consuming. Furthermore, any algorithms that are implemented in the fabric of the chip are essentially “frozen in silicon.” This inherent inflexibility becomes a problem given the considerations outlin...
The transport layer is responsible for end-to-end communication and provides error-free delivery of data. This layer can transport the data through a connection-oriented or connectionless layer. The two protocols used in the transport layer are user datagram protocol (UDP) and TCP. ...
An FPGA becomes a customized hardware device by configuring its PLBs and interconnects using a standard hardware description language (HDL) like Verilog or VHDL. Specific FPGA-based functions, as well as the interconnects between those functions, are “described” in an HDL. The description is com...
The initial design representing the desired functionality is described using a hardware description language like VHDL or Verilog or through schematics capture. Functional Verification Extensive simulations are run to verify logic functionality and that the design meets the specifications before synthesis. Log...
