Unlike a register, it can save the current value until another value is assigned to it. In the process of maintaining the current value, there is no need for the drive source to act on it. If no value is assigned to the register variable, its initial value is x. The register type va...
Then we have another common type of code, where one reg variable is driven from more than one always block. Well it will surely cause synthesis error.Example - Initial Statement 1 module synthesis_initial( 2 clk,q,d); 3 input clk,d; 4 output q; 5 reg q; 6 7 initial begin 8 q ...
Hover a variable name to quickly see the runtime value in tooltip.Why choose DVT Debugger Debug from the same place where you write code. Commonly used debug operations like adding breakpoints, stepping, moving up and down the call stack, or changing values are just a click away in the DVT...
Inputs : internally must always be of type net, externally the inputs can be connected to a variable of type reg or net. Outputs : internally can be of type net or reg, externally the outputs must be connected to a variable of type net. Inouts : internally or externally must always ...
?? Property – a variable that holds data. In Verilog, this is a signal such as a register or wire. ?? Method – the procedural code that manipulates variables, contained in tasks and functions. Verilog modules have tasks and functions plus ...
In Verilog, when you create a variable inside a part of the code called an always block without saying if it’s a wire or a reg, it’s automatically seen as a reg. But if you make a variable outside of this always block, usually within the main module, without specifying if it’s...

It would appear as a “member variable” for the driver. A stream might also be created at the top level – a generic stream for example that contains all the error transactions from a test bench. Any error that is seen is immediately placed on the error stream at the top level. ...
