Automatically target a wide variety of devices and boards. Design and verify high-level hardware functionality and architecture in context of your mixed analog, digital, and software system.

Native floating point HDL code generation simplifies workflows for high-accuracy prototyping. Design and generate code for signal processing and controls applications that require the performance and efficiency of custom digital hardware.

Deploy to preconfigured software-defined radio SDR platforms or to custom target hardware. Simulate with plant models, deploy to prototype systems, and reuse models for production deployment. Connecting algorithm design to hardware implementation involves more than just HDL code generation. Learn the best practices used in prototyping and production workflows. Develop algorithms that work efficiently on streaming data.

Fixed-point quantization trades off numerical accuracy for implementation efficiency. Automate fixed-point quantization, synthesize using native floating point, or use a combination of each.

Apply shift-left verification to eliminate bugs early and ensure that the hardware functions as required in the system context. Select a Web Site.

Hardware Description Language Hardware description language HDL is a specialized computer language used to program electronic and digital logic circuits.

In the AND gate example, first the library definitions are given. Then the entity declaration. Here the data type of the input and output is bit type which represents 0 and 1 values. Generally in VHDL data types are classified as scalar, composite, access, standard logic and file types. The words in color are the generally known as reserved words in VHDL. After the entity description, the architecture is defined, which involves the design of the gate.

The relational, logical, adding, miscellaneous, sign and multiplying are generally the operators present in VHDL. The model will clearly define the interconnections also. Here each component in the circuit is modeled as an entity. In the structural AND gate example, after defining the library and the entity, the component is defined.

This model allows a hierarchical design. In this model, we can use if-else, for loops, while statements and case statements too. Verilog generally defines each circuit using a module. The module will generally involve the name of the design, its inputs and outputs and functionality. In Verilog we generally use wires and registers to define the variables.

Generally, Verilog involves arithmetic, logical, relational, equality, bitwise, reduction, shift, concatenation, replication and conditional operators.

Here we use always block were the statements are written. Reg is used to declare the variable. Benefits of HDL The major benefit of the language is fast design and better verification. User Review 0. Please login to add review.
