Perl 5 has built-in, language-level support for associative arrays. Modern Perl refers to associative arrays as hashes; the term associative array is found in older documentation but is considered somewhat archaic. Perl 5 hashes are flat: keys are strings and values are scalars.
In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
SystemVerilog for register-transfer level (RTL) design is an extension of Verilog-2005; all features of that language are available in SystemVerilog. Therefore, Verilog is a subset of SystemVerilog. Therefore, Verilog is a subset of SystemVerilog.
c = a + b In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also ...
The always keyword acts similar to the C language construct while(1) {..} in the sense that it will execute forever. The other interesting exception is the use of the initial keyword with the addition of the forever keyword. The example below is functionally identical to the always example above.
SystemVerilog DPI (Direct Programming Interface) is an interface which can be used to interface SystemVerilog with foreign languages. These foreign languages can be C, C++, SystemC as well as others. DPIs consist of two layers: a SystemVerilog layer and a foreign language layer. Both the layers are isolated from each other.
SA-C programming language; Cascade (C to RTL synthesizer) from CriticalBlue; Mitrion-C from Mitrionics; SPARK (a C-to-VHDL) from University of California, San Diego [4] VLSI/VHDL CAD Group Index of Useful Tools from Case Western Reserve University [5] MyHDL is a Python-subset compiler and simulator to VHDL and Verilog [6]
Many programming languages provide hash table functionality, either as built-in associative arrays or as standard library modules. In JavaScript , an "object" is a mutable collection of key-value pairs (called "properties"), where each key is either a string or a guaranteed-unique "symbol"; any other value, when used as a key, is first coerced ...
