hi,

Want to divide a number by 21 in verilog code, but it is giving an error saying, Second Operand should be power of 2.

you can use a division ip core for this .
how did you get that error ??
or else you can design a divider. but using division ip core is better(i mean not time consuming).

Yes,. Actually I don't know IP core, so either you can explain how to do division with IP core or you can help me design a Divider,.

dipih, division by shifting is only valid for division with denominators that are a power of 2.

sorry for the incomplete reply ads-ee. normally it is done by shifting followed by substraction.before shifting we need to arrange the dividend and divisor in proper manner.

may be other methods are also there...
