problem with dcm_sp - doesn't recognize the change

[mersault]

Hello

I have a problem with this item.
I put one in my design and i put some values for the clkdiv variable.
Then I chaged that value but ISE doesn't recognize the change, the clock is the same as the first time that I ran the program.

Is this a bug from ISE?
Do you have a solution?

Greetings

problem with dcm_sp

thank you for your answer, but that's not the problem..
in simulation works well..

but when i download the .bit file to the fpga, the system has the same frequency no matter how many times i changed the frequency in the schematic with the dcm

Re: problem with dcm_sp

Sorry,

DCM_SP has been plagued with problems through several versions of ISE.

What versions are you using, including service packs?

Are you using a Dev Board, if so what the model?

Have you checked out the other postings in this forum for DCM_SP?

I maybe able to recreate the problem here, I have several Dev boards and a couple of ISE versions.
