Can there be cases where an if else statement is outside an always block?

Re: if else statement outside the always construct

Many.

In an initial block, function or task, generate block, constraint, ...

Re: if else statement outside the always construct

How can an if-else be inside a constraint? Can you please provide an example?

We always see if-else statement to be present inside an always statement.

Can if-else statement be written without an always statement inside functions or tasks?

Can case statement be written without an always statement inside functions or tasks??

Can case statement be outside an always block?

Thank you for replies.

Regards

See section 18.5.7 if-else constraints if the 1800-2012 LRM

It might help to explain where your doubts are coming from?

Hello

Right now I do not have the LRM in front of me. Can you please yourself explain in that case?

Not prior to SystemVerilog.
But with SystemVerilog you can have

class A
rand bit [7:0] len;
rand enum {big,middle,little} mode;
constraint c {if (mode == little)
                    len < 10;
                   else if (mode == big)

                   len > 100;}
endclass
