Yes, there is a difference :) “!” in Verilog represents the logical not operator and returns one if its input is zero and zero otherwise. “~” OTOH, is the *bitwise negation* operator and it performs a bitwise complement of its input. If you’re working with one bit, or one bit of a bit vector, then there is no difference, practically. The module counter has a clock and active-low reset (n) as inputs and the counter value as a 4-bit output.. The always block is executed whenever the clock transitions from 0 to 1, which signifies a positive edge or a rising edge..

The module counter has a clock and active-low reset (n) as inputs and the counter value as a 4-bit output.. The always block is executed whenever the clock transitions from 0 to 1, which signifies a positive edge or a rising edge.. The output is incremented only if reset is held high or 1, achieved by the if-else block. If reset is low at the clock's positive edge, then output is reset to a

Suppose ‘for i = 1 to N’ is a loop’, then, in software ‘i’ will be assigned one value at time i.e. first i=1, then next cycle i=2 and so on. Whereas in Verilog, N logics will be implement for this loop Verilog can be used at several levels automatic tools to synthesize a low-level gate-level model High-Level Behavioral Register Transfer Level Gate Level A common approach is to use C/C++ for initial behavioral modeling, and for building test rigs . Courtesy of Arvind L03-3 The verilog always block can be used for both sequential and combinational logic.

It provides the ability for the design to be built based on Verilog parameters. These statements are particularly convenient when the same operation or module instance needs to be repeated multiple times or if certa 1-2 Verilog-A Overview and Benefits Verilog and VHDL are the two dominant languages; this manual is concerned with the Verilog language. As behavior beyond the digital performance was added, a mixed-signal language was created to manage the interaction between digital and analog signals. A subset of this, Verilog-A, was defined. Verilog 2 - Design Examples 6.375 Complex Digital Systems Christopher Batten February 13, 2006 6.375 Spring 2006 • L02 Verilog 1 - Fundamentals • 18 Primary Verilog data type is a bit-vector where bits can take on one of four values Z High impedance, floating X Unknown logic value 1 Logic one 0 Logic zero Value Meaning An X bit might be a 0, 1, Z, or in transition.

Negative numbers are represented as 2’s compliment numbers !!!!! Use negative numbers only as type integer or real !!! Verilog Bitwise Operator There are four basic types of Bitwise operators as listed in the following table.

the top of a Verilog module parameter BITS = 32; I need a counter to count down from BITS to zero (inclusive) so the counter needs to be something like floor(log2(BITS)) + 1 wide. For example, if the parameter is 32 the counter needs to be 6 bits wide and if the parameter is 8 the counter needs to be 4 bits wide.

Verilog Modules I Modules are the building blocks of Verilog designs. They are a means of abstraction and encapsulation for your design.
