2015, Digital Integrated Circuit Design Using Verilog and SystemverilogRonald Mehler Chapter Getting Started Example 1-24 Process Syntax <process name>: Process (sensitivity list) Begin <sequential statements>
In general, a SystemVerilog always statement is written in the form always @(sensitivity list) statement; The statement is executed only when the event specified in the sensitivity list occurs. In this example, the statement is q <= d (pronounced “q gets d”). Hence, the flip-flop ...
Verilog-2001 adds a new wild card token, @*, which represents a combinational logic sensitivity list. The @* token adds to the sensitivity list all nets and variables that are read by the statements in the always block.Example: always @(posedge Clk or negedge Reset) always @(negedge Reset...
The @( ) construct in the Verilog HDL is used to control the execution of procedural statements in a Verilog initial or always procedure. This construct delays the execution of the next statement until any signal in the list changes value. The list of signals is often referred to as a “...
20391 - XST - "ERROR:Xst:1468 - "file.v" line xx: Unexpected event in always block sensitivity list" Description The following error occurs when I try to use the Verilog 2001 combinational sensitivity list (always @*) when reading a two-dimensional array: "ERROR:Xst:1468 - "file.v" li...
