assign c = b; // c = 001 <-- bug my_module i1 (d,e); // d and e are implicitly one-bit wide if not declared. // This could be a bug if the port was intended to be a vector. 即assign语句将信号传递给一个没有声明的网络时会隐式声明一个1bit信号;尽管流向这根线的信号是多b...

Avoid unnecessary printing or other additional commands because the run-time context is automatically fetched from the simulator. The call stack and local variables are available to be analyzed anytime the simulator hits a breakpoint. Take advantage of all DVT Eclipse IDE's features that help navig...

常见的条件控制主要是指if-else,和case,if-else的用法也和C类似。case语句在verilog中经常用的,与C中有所不同,不需要在后面加break。 systemverilog中加入了unique-if和priority-if. module tb; int x = 4; initial begin // This if else if construct is declared to be "unique" ...
Add one space before type parameters, except when the type is part of a qualified name. A qualified name contains at least one scope :: operator connecting its segments. A space in a qualified name would break the continuity of a reference to one symbol, so it must not be added. Paramet...
Ans : this loop executes continuously and never completes until you break it intentionally. 39. When generate statements are used? Ans : Generate statements are used when the same operation or module instance is repeated for multiple bits of vector. 40. List out the different methods to create...
Only the statements in the first matching case-item are executed (remember there is an implied ‘break’ at the end of every case item). Thus, there is an implied priority - case items at the top have higher priority than the bottom ones. ...
• Case sensitivity: Verilog is case sensitive! Keywords must be typed with proper casing (lowercase) and any user named inputs, outputs, or other pieces of code must always be referred to as they were first declared. • Indentation: Although not as apparent in this example, indentation ...
