From what we have learnt in digital design, we know that there could be only two types of digital circuits. One is combinational circuits and the second is sequential circuits. There are very few rules that need to be followed to get good synthesis output and avoid surprises. ...
Well this rule applies to combinational blocks (blocks with edge sensitive lists are sequential blocks); let's look at the following example. Bad Code 1 always @ (b or c) 2 begin 3 if (b) begin 4 a = c; 5 end 6 end You could download file latch_bad.v here In the code ...
Ideal for combinational logic Ideal for sequential logic 34. What are Verilog full case statements and Verilog parallel case statements? Verilog’s full case statements cover all potential input conditions, ensuring explicit definition and execution of associated statements for each match within the case...

Verilog has a single always block for the implementation of combinational and sequential logic. the system contains always_comb, always_ff and always_latch procedural blocks. Verilog supports a structured paradigm, whereas it supports structured as well as to object-oriented paradigms and artefacts. ...
