The Component In Arx, the component is the basic building block of hardware, comparable to a module in Verilog or the entity-architecture combination in VHDL. Example 1: Register The code below shows one of the simplest components that one could describe in Arx (say, the

Simulation Guide for C++ Generated Code Suppose that you generate C++ code from Arx source file foo.arx. The result is a C++ class called foo the description of which is distributed across the files foo.h and foo.cpp. Hierarchy that may have been present in the original Arx description is not preserved. The execution model that has been chosen for simulation requires the design to be flattened.

Statements Statements are the Arx language elements that are found in a component description or a function declaration between the keywords begin and end. In this section, the different type of statements are presented. Assignment The assignment statement is used to specify a new value for a signal, where a signal is either a register or variable (see the page on

declarations - [Generic Declaration]

Declarations This section discusses all possible declarations that are allowed in an Arx component descripition. Declarations can be made in the first part of a component description, before the occerrence of keyword begin. There are two categories of declarations in Arx:

Instantiation The use of a component inside another component is called instantiation. The component that is instantiated, is the instance. A complex design becomes manageable by subdividing it into smaller subcomponents. Recursively subdividing these subcomponents results in a

syntax - added section on case sensitivity

The Arx Syntax and Semantics General The Arx language has a mainstream syntax comparable to the syntax of languages as C, Pascal, Matlab, or VHDL. The most deviant syntax feature is maybe that no semicolons are used at the end of statements. Case Sensitivity Arx is case sensitive. All keywords should be written in lower case. Identifiers can have upper and lower case characters. It is, however, not recommended to rely on case for distinguishing identifiers. VHDL, for example, is not case sen…

expressions - typography of shift operators fixed

Expressions and Operators Arx does not differ much from other mainstream languages in the way it deals with expressions and operators. Parentheses ( and ) can be used to override default precedence when grouping operands (“multiplication binds stronger than addition

Arx Manual Arx is a domain-specific hardware-description language intended for hardware design at the register-transfer level (RTL). Arx is also a toolset which currently consists of two code generators: * A C code generator on behalf of efficient, zero-delay simulation.

Simulation Guide for VHDL Simulating the VHDL generated from Arx is straightforward. As opposed to the generated C++, the hierarchy of the Arx source code is preserved in the VHDL. For source code in the file foo.arx, the VHDL file foo.vhd is generated. Top model
