Can pow() be directly used as size of port during port declaration?

[acc_sysC]

For example,

#include <cmath>

template<int N, int M> class xyz: public sc_module

{

public:

sc_in<sc_int<pow(2,N)*M>  > IN;

..

..

};

Is this possible?

This question has nothing to do with SystemC. If you have a C++ class templatized on a numeric, can you pass a non-const parameter to it?
 

// Given:
template<int N>
class Foo { ... };

int bar() { ... };
int i;

// Is this legal?
Foo<bar()> f0;
// Or even:
Foo<i> f1;

For what you are trying to do, `pow(2, N)` can be replaced with `1<<N`

@karthickg Thanks! that makes sense. It works!
