Like 1. A signal var (usually input) attached to a module instance inside a container module to a (valid) port (of instance) which has not been declared either as wire or reg in the container module. The tool probably will throw out error like object "" on left...
The error message from both VCS and nLint is that indentifiers x1 and y1 have not been declared. But they have been declared within previous generated if statements - what is the problem here? === The wiresx1andy1are defined outside of scope of the assignment. One solution is to add an...
We’ve not had a chance yet to fully explore all the reasons for the speedup, but initial research has turned up several reasons for this. First, in 64bit mode, about twice as many registers are available to the compiler, allowing commonly used varaiables to be kept inside the CPU longer...
verification of integrated circuit design can play a key role). When an instance calls a module, it is necessary to arrange the port connections in the order in which the module is declared. This top-level module does not need to be called by the outside world, so it has no input and...
This feature has been taken from VHDL with some modification. It is possible to use it for loops to mimic multiple instants. Below is an example of usage of Verilog 2001 generate statement. 1 module generate_example(); 2 3 reg read,write = 0; 4 reg [31:0] data_in = 0; 5 reg [...

Do not use the Verilog-95 list style. The port declaration in the module statement should fully declare the port name, type, and direction. The opening parenthesis should be on the same line as the module declaration, and the first port should be declared on the following line. The closing...
