Integer larger than 2147483648

--- Quote Start ---

Hello all,

As written in title, I want to know how to manipulate integers larger than 2147483648.

I am trying to realize 8th order IIR band pass filter whose transfer function has small coefficients in numerator compared to denominator and this causes calculation result to be larger than 2147483648.

So I want to know how to manipulate integers larger than 2147483648...

I heard verilog can cope with integers larger than 2147483648 but is it true?

Anyway, any helps are appreciated.

Sincerely,

Yukihiro

use signed type as wide as you wish. I don't know of limitations to that apart from resource.

Thank your for your quick reply, kaz!!

I am pretty surprised that "signed" (and resize function, in my case) is very useful...
