A static array is one whose size is known before compilation time. In the example shown below, a static array of 8-bit wide is declared, assigned some value and iterated over to print its value. Static arrays are further categorized into packed and unpackedarrays. Unpacked arrays may be fixed-size arrays, … Visa mer A dynamic array is one whose size is not known during compilation, but instead is defined and expanded as needed during runtime. A dynamic array is easily recognized by its empty square brackets [ ]. Visa mer A queue is a data type where data can be either pushed into the queue or popped from the array. It is easily recognized by the $ symbol inside square brackets [ ]. Visa mer An associative array is one where the content is stored with a certain key. This is easily recognized by the presence of a data type inside its square brackets [ ]. The key is represented inside the square brackets. Visa mer WebbSystemVerilog has the array assignment operator '{...} in addition to the concatenation operator {...}. Concatentation is for packed arrays - basically you combine multiple signals into a single bus. wire [7:0] a = {4'd7, 4'd14}; You can nest concatenation operators too.
