How to increment a sc bitvector of width > 32

[chetha]

Hi
I am trying to implement a 40 bit counter in systemC
I had ttried with the following code

sc_bv <40> counter;
............
............
counter = counter.to_ulong()+1;

Even I tried counter.to_uint64()+1 also
The issue I am facing is after FFFFFFFF the counter value is 0 but not 1FFFFFFFF

Is there any short cut other than splitting the counter into 8 and 32 bit wide vectors ans incrementing them separately

Regards
Chethan

Hi Chetan,

you declared the counter as ulong.
ulong is nothing but 32-bit.
Thats y u'r counter value become 0 after FFFFFFFF.
